Safety Precautions
The following safety precautions should be observed before using this product and any asso-
ciated insrmmentation. Although some instmments and accessories would normally be used
with non-hazardous voltages, there are situations where hazardous conditions may be present.
This product is intended for use by qualified personnel who recognize shock hazards and are
familiar with the safety precautions required to avoid possible injury. Read the operating ins
formation carefully before using the product.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of
equipment, for ensuring that the equipment is operaled within its specifications and operat-
ing limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety
procedures and proper use of the insmnncnt. They must be protected from electric shock and
contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating. for
example, setting the line voltage or replacing consumable materials. Maintenance procedures
are described in the manual. The procedures explicitly state if the operator may perform them.
Otherwise, they should be performed only by service personnel.
Service personnet are trained to work on live circuits, and perform safe installations and re-
pairs of products. Only properly trained sewice personnel may perform installation and ser.
vice procedures.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on
cable connector jacks or test fixtures. The American NationaJ Standards Institute (ANSI)
states that a shock hazard exists when voltage levels greater than 30" RMS, 42.0 peak, or
60VDC are present. A good safety practice is to expect that hazardous voltage is present
in any unknown circuit before measuring.
Users of this product must be protected from electric shock at all times. The responsible body
must ensure that WWFare prevented accessand/or insulated from every connection point. In some
cases, connections must be exposed to potential human contact. Product users in these circum-
stances must be trained to protect themselves from the risk of elecnic shock. If the circuit is ca-
pable of operating at or above 1wO volts, no conductive part of the circuit may be exposed.
As described in the lntemational Electrotechnical Commission (IEC) Standard IEC 664, dig-
ital multimeter measuring circuits (e.g., Keitbley Models 175A, 199. 2000, 2001. 2002, and
2010) are installation Category II. All other instruments' signal terminals are Installation Cat-
egory 1 and must not be connected to mains.
Do not connect switching cards directly to unlimited power circuits. `Ibey are intended to be
used with impedance limited sources. NEVER connect switching cards directly to AC mains.
When connecting sources to switching cards, install protective devices to limit fault current
and voltage to the card.
Before operating an instrument, make sure the line cord is connected to a properly grounded
power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear,
cracks, or breaks before each we.
For maximum safety, do not touch the product, test cables. or any alher insbunents while pow-
er is applied to the circuit under test. ALWAYS remove power from the entire test system and
discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or
removing switching cards, or making internal changes, such as installing or removingjumpers.
Do not touch any object that could provide a current path to the common side of the circuit
under test or power line (earth) ground. Always make measurements with dry hands while
standing on a dry, insulated surface capable of withstanding the voltage being measured.
The instrument and accessories most be used in accordance with its specifications and op-
erating instructions or the safety of the equipment may be impaired.
Do not exceed the maximum signal levels of the insuuments and accessoties. as defined in
the specifications and operating information. and as shown on the instrument or test fixture
panels, or switching card.
When fuses arc used in a product. replace with same type and rating for continued protection
against fire hazard.
Chassis connections most only be used as shield connections for measuring circuits, NOT as
safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under
test. Safe operation requires the use of a lid interlock.
1fa @ scow is present, connect it to safety earth ground using !he wire recommended in
tic user documenmtion.
The/& sy mblo on an insb'ument indicates that the user should refer to the operating in-
structions located in the manual.
The A symbol on an instmmcnt shows that it can sowce or measure loo0 volts or more, in-
cluding the combined effect of normal and common mode voltages. Use standard safety precau-
tions to avoid personal contact with these voltages.
The WARNING heading in a manual explains dangers that might result in personal injury or
death. Always read the associated information very carefully before performing the indicated
procedure.
The CAUTION heading in a manual explains hazards that could damage the instrumem.
Such damage may invalidate the warranty.
instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains cir-
cuits, including the power uansfomxr, test leads, and input jacks, most be purchased from
Keithley Instruments. Standard fuses, with applicable national safety approvals, may be used
if the rating and type are the same. Other components that are not safety related may be pur-
chased from other suppliers as long as they are equivalent to the original component. (Note
that selected parts should be purchased only through Keithley Insnuments to maintain acco-
racy and functionality of the product.) If you are unstxe about the applicability of a replace-
ment component, call a Keithley lnsouments office for information.
To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior
of the instrument only. Do not apply cleaner directly to the insounent or allow liquids to
enter or spill on the instrument. Products that consist of a circuit board with no case 01chas-
sis (e.g., data acquisition board for installation into a computer) should never require clean-
ing if handled according to instructions. If the board becomes contaminated and operation
is affected, the board should be returned to the factory for proper cleaning/servicing.

SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
The Model 7063 is an RF scanner card that switches RF signals (up to
500MHz) from one channel to another. All channels switched are
terminated into 5011when not selected. When a channel is closed, the
RF signal is routed from the input to the output. The Model 7063
works in conjunction with a scanner mainframe such as the Keithley
Model 705 or Model 706.
The Model 7063 incorporates two 1 X 5, switches on each card.
Each switch has a separate common (ground). This allows two
signals to be switched at the same time. One 1 X 5 switch could be
cascaded with the other 1 X 5 switch (on the same card) for a 1 X 10
switch configuration. Thus, the Model 7063 is configurable for
several different switch configurations.
Specified relay life is greater than 100,ooO closures. Cables are routed
from the rear of the card. The front plugs into the mainframe (e.g.
Model 705 or Model 706). The mainframe must be in the matrix
mode or 2-pole mode to operate the channels on the Model 7063
card. BNC connectors allow easy connections to input/output signal
paths.
1.2 WARRANTY INFORMATION

SECTION 2
OPERATION
2.1 INTRODUCTION
This section provides the information necessary to use the Model
7063 with an appropriate Keithtey scanner mainframe such as the
Model 705 or Model 706. Once the card is configured and placed in
the appropriate slot in the scanner mainframe, refer to the scanner
mainframe's instruction manual for complete operating details. This
section is divided into five parts: Safety Precautions, Wiring, In-
stallation, Operation and Switch Terminology.
2.2 SAFETY PRECAUTIONS
1. Make sure the scanner mainframe is grounded through a properly
earth grounded receptacle before operation.
2. Inspect all test lead connections for wear and defects such as
cracks, exposed wires, (etc). Correct any defect found before
operating the scanner card with the mainframe.
3. Do not exceed the Model 7063's maximum allowable signal level
as defined in the specifications.
4. Turn off all power supplies and discharge any residual power
before installing or removing the Model 7063 from the scanner
mainframe.
5. Turn off all power supplies and discharge any residual power
before installing or removing any wires from the Model 7063.
2.3 WIRING
Each channel on the Model 7063 consists of two siogle pole. Form C
relays and a 5011 terminating resistor. The 5On terminating resistor
consists of two lOOn resistors in parallel. Having two resistors in
parallel reduces the overall inductance of the resistors at higher fre-
quencies. Input/output connections should be made using a high
quality 5Ofl coaxial cable with a standard mate RNC connector on
the Model 7063 end. Wiring diagram nomenclature is contained on
schematic diagram 7063.106 located at the end of this manual.
Cables are routed to the rear of the card, while the front plugs into
the scanner mainframe (e.g. Model 705 or Model 706). The main-
frame must be in the matrix mode or the Z-pole mode to operate the
3
channcts on the Model 7063 card. Refer to Tables 2-I and 2-2. To
configure a card for operation. it must have a minimum of two con-
nections. `These two connections are listed as follows:
I. Input
2. output
In general:
1. The input is the signal path that is switch to one of several points.
The selected output is the path (channel) to which the input is
switched.
2. The output is the selection of one of several sources. Any of seven
inputs selected can be routed to the output for measurement or
processing. The 1 X 5 switch has six inputs which consist of five
channel selects and a through connection. The through connector
may be left open or connected to a source or terminator.
NOTE
Keep in mind that when a channel is open it is terminated
through 500 to ground.
2.3.1 1 x 5 Switch
With a 1 X 5 switch, the Model 7063 can switch one signal to any
one of five signal paths. Also, any one of five channels can be
switched to one signal path. Using the through connection as a sixth
channel (1 of 6) any one of six inputs can switch to one output. Also,
one input can be switched to any of six outputs. For example: Switch
1 OUT/IN can switch a signal to channels l-l, 2-1, 3-1, 4-l and 5-l.
Also, channels l-l, 2-1, 3-l. 4-l or 5-l can switch to SWITCH 1
OUT/IN. Only one channel will switch at a time on a 1 X 5 switch.
The Model 7063 incorporates two 1 X 5 switches so that two signals
can be switch at the same time. Each of the 1 X 5 switches incor-
porates a separate common (ground). For example: SWITCH 1
OUT/IN can switch a signal to channels l-l, 2-1, 3-1, 4-1 or 5-l;
while SWITCH 2 OUT/IN switches another signal to channels 1-2,
2-2, 3-2, 4-2 or 5-2. Refer to Figure 2-1.
The advantage of using the 1 X 5 switch is that one channel will ac-
cess any one of five outputs. Also, one of five channels will access
one output. There are two separate 1 X 5 switches on each Model
7063. This allows two separate signals to be switched simul-
taneously.

To operate the channels (open or close) once they arc configured,
plug the scanner card into the scanner mainhme and consult the
scanner mainframe's instruction manual for complete details.
CAUTION
Do not exceed the voltage and frequency apecifics-
tions of the Model 7063 scanner card. Instrument
damage may occur.
2.3.2 1 of 11 Switch
The Model 7063 can be configured as a 1 of 11 switch. To configure
the I of 11 switch, SWITCH 1 THROUGH IN/OLJT must be con-
nected to SWITCH 2 OUT/IN (I1007 connected to J1008). Another
possible I of ~1~1 switch is SWITCH 2 THROUGH IN/OUT con-
nected to SWITCH 1 OUT/IN (J'lo14 connected to JlOOl). In either
of these configurations one channel can be switch to any one of 11
signal paths. Also. any one of 11 channels can be switched to one
signal path. For example; SWITCH 1 OUT/IN will switch toany one
of the following channels:
1. CH~l-1
2. CH2-1
3. CH3-.I
4. CH4-1
5. CHW
6. W-2
7. CHZ-2
8. CH3-2
9. CH4-2
10. CH5-2
11. CHb-2
Refer to Tables 2-l and 2-2. Refer to schematic diagram 7063-106 at
the end of this manual.
In another example, if SWITCH 1 OUT/IN is connected to SWITCH
2 THROUGH IN/OUT (JlOOl connected to J1014), then SWITCH 2
OUT/IN will switch to any one of the following channels:
6
1,. CHl-1
2. CH2-1
3. CH3-1
4. CH4-I
5. CH5-1
6. CH6-1
7. w-2
8. CHZ-2
9. CH3-2
10. CH4-2
11. CH5-2
The advantage of cascading the two 1 X 5 switches is that one chan-
nel can access any one of 11 channels instead of one of five channels.
Refer to Pigure 2-2.
To operate the channels (open or close) once they are configured,
plug the Model 7063 into the scanner mainframe and consult the
mainframe's instruction manual for details. The mainframe must be
in the matrix mode or the 2-pole mode to operate the channels on the
Model 7063 card.

equipment from the acenner card before instal-
ling/removing the card.
before installing the Model 7063 into the scanner mainframe, it must
be wired with the desired configuration. Refer to paragraph 2.3.
Once the card is configured, install it into the scanner mainframe.
Plug the scanner card into the appropriate slot in the rear panel of the
mainframe. In some mainframes, the scanner card is placed horizon-
tally into the unit. The cards are labeled top or bottom. In other
mainframes, the scanner cards are placed vertically in the unit and
numbered l-10. The scanner card is placed in the mainframe with the
card edge first. Align the card with the grooves in the slot and insert
the card to its full depth into the mainframe. Make sure the card is
properly seated into the connector in the mainframe. When the card
is fully inserted, the locking tabs should be pushed forward to the
center of the card to lock it in the mainframe.
NOTE
Refer to the scanner mainframe's instruction manual for
complete details.
2.4.1 Removal
To remove a scanner card, first turn off the mainframe and all other
equipment connected to the card. Unfasten the locking tabs on the
card by pulling the tab outward. Grasp the end of the card and
carefully pull it out of the mainframe.
2.6 OPERATION
Model 7063 operation consists of two parts:
1. Wiring the Model 7063 for the desired configuration
2. Mainframe control of the channels.
Refer to paragraph 2.3 for wiring information. Refer to the scanner
mainframe for information concerning the control of the channels.
Refer to Table 2-l for Model 7063 connector/mainframe relation-
ship. The scanner mainframe must be in the matrix mode (Program
6. pole 0) or the Z-pole mode (Program 6. pole 2) to operate the chan-
nels of the Model 7063 card.

The preceding connector/channel assignment is for slot 1 of the
Model 706 and top card slot of the Model 705. More channels are
available when connecting several Model 7063 cards and several
mainframes together. The Model 705 has two card slots. This meam
that for every Model 706 a matrix of 1 of 21 could be constructed.
With a maximum of five Model 70% daisy chained, a switch of 1 of
101 could be constructed.
9
NOTE
The frequency response for the larger switching schemes
is not as good as a single 1 X 5 switch.
The Model 706 has 10 card slots. This means that for every Model
706 a switch of 1 of 101 could be constructed. With a maximum of
five Model 706s daisy chained, a switch of `I of 100'1 could be con-
structed.
NOTE
Refer to the mainframe's instruction manual for informa
tion concerning daisy chain operation.
To construct such a large switching scheme, 50 Model 7063 cards
and five Model 706 mainframes are required. Connections between
the cards and mainframes is accomplished using the following for-
mat.
Connect card 1, CH6-I to SWITCH 2. To connect one card to
another, connect card 1, CH6-2 to card 2, SWITCH 1. The rest of the
cards are wired in the same manner. The connector/channel assign-
ment for the larger configurations are described in Tables 2-2 and
2-3.
2.6 SWITCH TERMINOLOGY
Throughout this manual the terminology Form C is used. The term
Form C is used in switch terminology and is described as follows:
1. Form A is a single pole normally open (SPNO) switch. Refer to
Figure 2-3. Example: A 2-pole switch normally open is classified as
a 2 Form A.
2. Form B is similar to Form A except that its contacts are normally
closed. Refer to Figure 2-3. Example: A 2-p& switch that is nor-
mally closed is classified as a 2 Form B.
3. Form C is shown in Vigurc 2-3 as a single pole double throw
switch. It could also bc a multiple switch such as a 2-p& This
would be classified as a 2 f:orm C.
