Notice
Hewlett-Packard to Agilent Technologies Transition
This documentation supports a product that previously shipped under the Hewlett-
Packard company brand name. The brand name has now been changed to Agilent
Technologies. The two products are functionally identical, only our name has changed. The
document still includes references to Hewlett-Packard products, some of which have been
transitioned to Agilent Technologies.

Safety Notes The following safety notes are used throughout this manual.
Familiarize yourself with each of the notes and its meaning before
operating this instrument.
Glution The caution sign denotes a hazard. It calls attention to a procedure
which, if not correctly performed or adhered to, could result in
damage to or destruction of the instrument. Do not proceed beyond a
caution sign until the indicated conditions are fully understood and
met.
Warning The warning sign denotes a hazard. It calls attention to a

result in injury or loss of life. Do not proceed beyond a warning
sign until the indicated conditions are fully understood and met.
General Safety Considerations
Warning Before this instrument is switched on, make sure it has been
properly grounded through the protective conductor of the ac
power cable to a socket outlet provided with protective earth
contact.
Any interruption of the protective (grounding) conductor, inside
or outside the instrument, or disconnection of the protective
earth terminal can result in personal injury.
Warning There are many points in the instrument which can, if contacted,
cause personal injury. Be extremely careful.
Any adjustments or service procedures that require operation
of the instrument with protective covers removed should be
performed only by trained service personnel.
Caution Before this instruct is switched on, make sure its primary power
circuitry has been adapted to the voltage of the ac power source.
Failure to set the ac power input to the correct voltage could cause
damage to the instrument when the ac power cable is plugged in.

Introduction This chapter describes the HP 85620A Mass Memory Module, provides
specifications and characteristics, and illustrates accompanying
accessories. The serial numbers covered by this document are also

HP 86620A Mass Memory Module Description
Note The spectrum analyzer save-trace registers 5, 6, and 7 are overwritten
when the module is connected to the its rear panel OPTION MODULE
CONNECTOR. These registers are used for module data and are not
available for spectrum analyzer operation. If you attempt to store
data to these registers while the module is attached, module operating
memory is corrupted.
The mass memory module is an optional memory package that is
attached to Hewlett-Packard portable spectrum analyzers. It provides
substantially greater user memory than other spectrum analyzer
products. This general-purpose memory may be used to store trace
data, downloadable programs (DLPs), limit lines, and variables. The
module memory is battery-backed. The battery needs to be checked
at least annually. Refer to Chapter 5, "Service," for information on
how to check the battery voltage.
The module is attached to the OPTION MODULE connector (53)
on the spectrum analyzer rear panel and locked into place with a
l/4-turn fastener. The module interface with the spectrum analyzer is
established through this connector.
Installation 1-l
Caution You must turn the spectrum analyzer OFF before attaching or
removing the mass memory module. Connecting the module while the
spectrum analyzer is ON can damage both the spectrum analyzer and
the module circuitry.
The connector pins on the module and on the spectrum analyzer are
electrostatic discharge (ESD) sensitive. Do not touch the pins on
either instrument unless you are adequately protected against ESD.
You may also store data on memory cards that are compatible with
the module. Memory cards contain lithium batteries which must be
checked at least annually. Refer to Chapter 5, "Service," for how
to check the battery. Instructions for installing memory cards and
batteries are in "Installing Memory Cards" in this chapter. (Option TO1
does not include memory card capability.)

Modules Covered by This Manual
Serial Numbers The serial-number label is on the rear cover (connector side) of the
mass memory module. The first five characters make up the serial
number prefix; the last five are the suffix. The only time the serial
prefix changes is when there are substantial changes to the module.
Suffix numbers are different for each module.
Firmware Revisions Mass memory module operation is controlled by ROM (read-only
memory) firmware. The module firmware version is displayed
after pressing the [MODULE) key on the spectrum analyzer. Refer to
`Pable l-l for firmware versions of the module that are compatible
with the different portable spectrum analyzers
It is possible to get a different set of functions from a given mass
memory module, depending on the firmware revision of the host
spectrum analyzer. In spectrum analyzers with firmware revision
960401 and later, the firmware that controls the mass memory module
actually resides in the host spectrum analyzer and contains a more
recent set of features and functionality. If that same mass memory
module is installed on a host spectrum analyzer with firmware
revision 941028 or earlier, the firmware that resides in the mass
memory module (revision A, B, or C) will control the features and
functionality of the module.

Auxiliary Interface Connector
The auxiliary interface connector allows the user, by way of the
spectrum analyzer, a method of providing minimal power to external
devices and to control or receive inputs from external devices. This
interface is to provide an alternative to HP-IB in the control of simple
switches in "Logic" mode and to control external devices in "Serial
Bit" mode. The "Serial Bit" mode is especially useful for Automated
Test Equipment (ATE) applications.
The Auxiliary Interface Connector has four output control lines
and one input line. In the "Serial Bit" mode one of the outputs is
designated as the serial line and another as the strobe. There are
actually two serial modes: "OUTPUT 99" sends out the data most
significant bit (MSB) first, and "OUTPUT 98" sends out the least
significant bit (LSB) first.
As implemented the Auxiliary Interface Connector runs open loop.
The serial data is clocked out as fast as the software can toggle the
data lines as illustrated in Figure l-3.
