1-2 General Information
Initial Inspection
Inspect the shipping containers for damage. If a shipping container or cushioning material
is damaged, it should be kept until the contents of the shipment have been checked for
completeness and the module has been checked mechanically and electrically. To determine
what accessories should have been shipped with the module, refer to \HP 70900B Local
Oscillator Source Accessories". Run the operation veri cation tests to check electrical
performance. (Refer to Chapter 4.)
If the shipping contents are incomplete, or the module does not satisfy the veri cation
procedures, notify the nearest Hewlett-Packard Sales and Service Oce. Hewlett-Packard will
arrange for repair or replacement of the equipment without waiting for a claim settlement.
Retain the shipping materials for the carrier to inspect.
Undamaged shipping materials should be kept. Original Hewlett-Packard shipping materials, or
equivalent, are required for system or module reshipment. Substandard packaging may damage
the instrument. For more information, refer to \If You Need to Contact Hewlett-Packard".

HP 70900B Local Oscillator Source
The HP 70900B local oscillator source (LO) is a 1/4-width module that ful lls three functions:
local oscillator, controller, and video processor.
The local oscillator circuitry supplies a swept signal that has a frequency range of
3.0 to 6.6 GHz. This signal is used by various modules and devices, including front-ends (RF
sections), tracking generators, and the external mixer interface module. For spans that are
less than or equal to 10 MHz, the sweep is fully synthesized using fractional-N techniques;
for spans that are greater than or equal to 10 MHz, lock-and-roll tuning is used.
The controller circuitry contains the system rmware. This rmware controls and coordinates
measurements between other system modules which are slave modules to the LO module.
Examples of slave modules are the RF sections, IF sections, and tracking generator modules.
The video processor circuitry digitizes the video signal received from the IF section and
processes this signal using normal (rosenfell), positive peak, negative peak, or sample
detection.
If the HP 70900B local oscillator source was ordered separately, not as part of a precon gured
system, refer to Chapter 2 for addressing and installation information and examples of rear
panel cable connections. Refer to the HP 70004A Color Display User's Guide for instructions
on installing the spectrum analyzer instrument keypad into the HP 70004A color display. Then,
refer to \Preparing an HP 70000 System for Use".

HP 70900B Local Oscillator Source Front-Panel Features
Note It is normal for the ERR and ACT LEDs to ash on, then o, during the module
self-test. Self-test occurs each time the instrument is turned on.

The numbers in the \Item" column of Table 1-1 refer to the callouts in Figure 1-1.
Table 1-1.
HP 70900B Local Oscillator Source Front-Panel Feature Descriptions
Item Description
1 The RMT LED lights if the analyzer is addressed by a computer. In addition,
depending on the instructions received from the computer, the LSN, TLK, or SRQ
indicators will also light.
2 The LSN LED lights when the analyzer is receiving data or instructions over
HP-IB.
3 The TLK LED lights when the analyzer is sending data or instructions over HP-IB.
4 The SRQ LED lights when the analyzer has requested computer service.
5 The ACT LED lights when a module is making a measurement and its master has
keyboard control of the display. The ACT LED of a module is only operative when
there is a display in the system and when the instrument is performing a
measurement.
6 The ERR LED lights when there is a problem (error) related to one or more
modules in the system. To learn the nature of the error and its source, press
4DISPLAY5, 4REPORT ERRORS5. The screen displays the error code and identi es the
module where the error originated.
7 The MEASURE LED lights as the analyzer sweeps each band and blanks during
retrace and between frequency bands.
8 The SELF TEST LED lights whenever the analyzer is testing itself.
9 The YTO Loop Unlock LED lights when a YTO hardware failure occurs.
10 IDL Loop Unlock LED lights when an idler hardware failure occurs.
11 FFS Loop Unlock LED lights when a fractional-N hardware failure occurs.
12 The 300 MHz CALIBRATOR Output provides a 010 dBm signal for the use as a
reference during spectrum analyzer calibration. Using this signal and internal
calibration routines the analyzer can correct for frequency errors in the resolution
bandwidth circuits and amplitude errors throughout the signal path.
13 The module hex-nut latch secures the module in an HP 70000 Series mainframe.
When the module is being installed or removed from a mainframe, an 8 mm
hex-ball driver is used to turn the module latch. For information on module
installation, refer to Chapter 2.

HP 70900B Local Oscillator Source Rear-Panel Features
The numbers in the \Item" column of Table 1-2 refer to callouts in Figure 1-2.
Table 1-2.
HP 70900B Local Oscillator Source Rear-Panel Feature Descriptions
Item Description
1 300 MHz OUT 1 and 2 provide 300 MHz, 0 dB signals that are used by other
modules in the system for reference and phase-locking.
2 EXT TRIG IN is a TTL input that is used for the external trigger functions of the
spectrum analyzer. When in external trigger mode, the spectrum analyzer begins a
sweep upon receipt of this signal.
3 HSWP IN/OUT has a TTL signal that is high any time the LO is sweeping. This port
works both as an output and an input, allowing other modules in the system to
interrupt the sweep.
4 100 MHz IN receives the 100 MHz, 0 dB signal input that is used by the LO for all
frequency synthesis and phase-locking. If this signal is not present, the LO will use
an internally generated 100 MHz signal which will result in reduced performance.
5 VIDEO IN receives a 0 to 2 V signal input that is the post-detected signal that will
be displayed on the screen. This signal is processed by the LO.
6 SWEEP provides a signal that is a linear 0 to 10 V ramp corresponding to the
sweep of the analyzer. There is no tuning information available from this signal.
It represents the x-axis of the display.
7 LO OUT provides the 3.0 to 6.6 GHz swept LO signal that is used for RF
conversion (heterodyning). The signal amplitude can vary from +7 to 15 dBm.
8 TUNE + SPAN OUT provides a signal that is proportional to the frequency of the
LO signal. The tune span signal varies 1.5 V per GHz with a range of 4.5 to 9.9 V.
9 The mainframe/module interconnect is a multiple-pin connector that plugs into
the mainframe when the module is installed in the mainframe. This connector
provides power-supply voltages and HP-MSIB connections for module
communication and control.

Initial System Power-On
The HP 70000 Series modular spectrum analyzer system is shipped as a precon gured system
model (for example, HP 71100C modular spectrum analyzer), with most rear panel inter-module
cables connected. (Some cables are removed for shipping.) The following procedure may be
used to ensure that proper initial conditions exist at power-on.
1. Locate the cables shipped with the system.
2. Inspect socket ends and cables for damage.
3. If the loose inter-module cables are intact, connect them. For information on rear panel
cabling examples, refer to Chapter 2. Make sure each rear panel inter-module cable is
connected securely.
4. Make sure the system line-voltage selectors are set to the same voltage as the power source.
5. Connect the power cables to the instruments rst, then plug the cables into the power
outlet.
6. If the LO module is located in the HP 70004A color display, perform the steps below in the
order shown. If the LO module is located in the HP 70001A mainframe, perform Step b rst
and then Step a.
a. Set the HP 70001A mainframe line switch to the on position and listen to verify that the
ventilation fan starts up.
b. Set the HP 70004A color display line switch to the on position and listen to verify that
the ventilation fan starts up.
7. Observe that the indicator lights ash on the front panels of each module. (Refer to
\HP 70900B Local Oscillator Source Front-Panel Features".)
8. Check to see that the STATUS indicator light labeled ACT on the modules in the selected
system remain lit. When two IF sections are in the system, only the one that is selected will
have its ACTive light on.
If the system responds properly, make sure that the system is allowed to warm-up before
running any system veri cation tests. Refer to \System Calibration Certi cation" and Chapter 3
for warm-up time requirements.

System Calibration Certi cation
To qualify a modular spectrum analyzer for calibration certi cation, allow the instrument
to warm up for at least 1 hour, then load and run the HP 11990A system performance test
software. The HP 11990A system performance test software is available through your local
Hewlett-Packard sales or service oces.
If all tests pass, a certi cation label may be applied to the front panel of the modular spectrum
analyzer system. The certi cation label indicates that the system has met certain speci cations.
All test routines must be passed before the system can qualify for a certi cation label. The
customer's own label may be applied, or an Hewlett-Packard service oce may perform the
calibration and apply a Hewlett-Packard certi cation label to the front panel of the system.
