Preamplier Modes

The preampliers have two modes: preamplier and bypass. (See Figure 1-1, Figure 1-2, and

Figure 1-3.) When used with the HP 70000 spectrum analyzer, the mode is \bypass." When the

preamplier is used without the 70900 LO master module, it's default mode is preamplier on.

Modes can be selected using either a softkey or a remote command. Information about using

the softkey to select the mode is given below. Refer to the system master's Programming

Manual for remote-operation information.

This option is available only for the HP 70620B. This option combines the

HP 70621A capabilities with the HP 70620B capabilities, extending the

module's low-end frequency range to 100 kHz. This results in a total frequency

range of 100 kHz to 26.5 GHz. PIN diode switches allow full-band sweep.

This option adds the latest controller-board/rmware upgrade kit for the HP

70900A Local Oscillator. This option is required if the existing system HP

70900A contains rmware version 850730 or 860203.

This option adds the latest RAM/ROM upgrade kit for the HP 70900 local

oscillator. This option is required if the existing system HP 70900 contains a

rmware version earlier than 900314. (Option 099 is not necessary if Option

098 is ordered.)

This option adds another set of the manuals that normally ship with the

Examples of Congurations Using Preampliers

The HP 70620B and HP 70621A preampliers can be used in a variety of congurations

depending on your application needs. If overload or multiple responses are a concern, an

HP 70600A or HP 70601A preselector can also be added to the system. Spur searching that

involves a carrier signal requires a preselector to eliminate analyzer image and multiple

responses. See Table 1-2 for examples of congurations for the following applications:

A system with a preamplier provides the highest sensitivity for testing low-level signals.

(See Table 1-2, example A.)

The preamplier precedes a preselector for best sensitivity. (See Table 1-2, example B.)

A preselector precedes the preamplier to minimize chances of the preamplier being

overloaded. The preamplier can be overloaded if the spur searching involves many

high-level signals or if a low-level signal of interest is in an environment containing

high-power signals. Because there is some insertion loss through the preselector, optimum

sensitivity is not achieved in this conguration. (See Table 1-2, example C.)

Bracketing a preselector with preampliers allows a large amount of gain for maximum

improvement in noise gure in a preselected receiver.(SeeTable 1-2, example D.)

Accessories

The HP 70620B and HP 70621A preampliers are available separately or as part of a

precongured system (which is assembled in a specic conguration in the factory).

Preampliers in precongured systems come with the RF cables that are needed for that

specic conguration. For a list of available system cables, refer to the Installation and

Verication Manual for the system master.

When a preamplier is ordered separately, it is shipped with a group of accessories that

allow the most common system congurations.Table 1-3 lists the accessories shipped with

preampliers when they are ordered separately.Table 1-4 lists accessories that are available,

but are not shipped with the preamplier. The accessories in these tables are those available at

the print date of this manual.

In Table 1-3 and Table 1-4 below, the information in the \L/R" columns refers to signal ow

\out" to \in" as viewed from the front panel. For example, if the signal source is to the left of

the signal destination when viewed from the front panel, a \L to R" cable is needed. Bends in

the semirigid cables make this distinction necessary.

Preparing a Static-Safe Work Station

Electrostatic discharge (ESD) can damage or destroy electronic components. Therefore,

all work performed on assemblies consisting of electronic components should be done at a

static-safe work station.

Figure 1-5 shows an example of a static-safe work station. Two types of ESD protection are

shown:

a conductive table mat and wrist strap combination

a conductive oor mat and heel strap combination

Figure 1-5. Static-Safe Work Station

These two types of ESD protection must be used together. Refer to Table 1-5 for a list of

Preparing a Static-Safe Work Station

Reducing ESD Damage

To help reduce the amount of ESD damage that occurs during testing and servicing use the

following guidelines:

Be sure that all instruments are properly earth-grounded to prevent buildup of static charge.

Personnel should be grounded with a resistor-isolated wrist strap before touching the center

pin of any connector and before removing any assembly from a piece of equipment.

Use a resistor-isolated wrist strap that is connected to the HP 70000 Series modular spectrum

analyzer system mainframe's chassis. If you do not have a resistor-isolated wrist strap, touch

the chassis frequently to equalize any static charge.

Before connecting any coaxial cable to an instrument connector for the rst time each day,

momentarily

short the center and outer conductors of the cable together.

Handle all PC board assemblies and electronic components only at static-safe work stations.

Store or transport PC board assemblies and electronic components in static-shielding

containers.

PC board assembly edge-connector contacts may be cleaned by using a lintfree cloth with a

If You Need to Contact Hewlett-Packard

Before calling Hewlett-Packard or returning your preamplier, please read your warranty

information. Warranty information is printed at the front of this document.

In any correspondence or telephone conversations, refer to the preamplier by its full model

number and full serial number. With this information, the Hewlett-Packard representative can

determine whether your unit is still within its warranty period.

Determining Your Preamplier's Serial Number

When a module is manufactured by Hewlett-Packard, it is given a unique serial number. This

serial number is attached to a label on the front frame or front panel of the module. A serial

number label is in two parts. (Refer to Figure 1-6.) The rst part makes up the serial number

prex and consists of four digits and a letter. The second part makes up the serial number

sux and consists of the last ve digits on the serial number label. The serial number prex is

the same for all identical modules; it only changes when a change in the electrical or physical

functionality is made. The serial number sux, however, changes sequentially and is dierent

for each module.

This chapter contains information needed to congure an HP 70620B or HP 70621A

preamplier in an HP 70000 Modular Measurement System and then check basic module

operation. Although the examples in this chapter show an HP 70620B, the same sequence can

be used to congure an HP 70621A in an HP 71100C system. For more detailed information

about system conguration and addressing, refer to the Installation and Verication Manual for

the system master (for example, HP 70900B).

Addressing the Module

Modules need an appropriate Hewlett-Packard Modular System Interface Bus (HP-MSIB) address

to be able to communicate with the master of the HP 70000 Modular Measurement System. The

HP-MSIB address is set using the module's ROW and COLUMN address switches.

Note

The module can be used in most system congurations without changing the

factory-preset address.

Determining the HP-MSIB Address

Both the HP 70620B and HP 70621A preampliers have a factory-preset HP-MSIB address of

3, 19 (row 3, column 19). Figure 2-1 shows the address map for a preamplier congured in

front of the preselected RF section in an HP 71210C system. The addresses in this gure are

the factory-preset addresses for the modules. If the preamplier is going to be used in an HP

70000 Modular Spectrum Analyzer System where the modules all have their factory-preset

addresses, the preamplier probably will not need to have its factory-preset address changed.

However, the preamplier's factory-preset address may need to be changed if the preamplier

Checking Module Operation

The operation of the preamplier in an HP 70000 Modular Spectrum Analyzer system is

checked by examining the front-panel LEDs, checking for error messages after the module's

power-on self-test has run, and measuring the +28 VDC OUT voltage.

Examining the Front-Panel LEDs

The power-on self-test runs automatically when power is rst applied to the module.The

front-panel LEDs ash on and then o during the self-test. Immediately after the self-test has

run, the ERR LED should beo. Refer to Chapter 5, \Troubleshooting," if the ERR LED is on.

Verication

This chapter contains the test necessary to verify the +28 VDC OUT voltage specications.

The system-level performance specications for the preamplier are in the Installation

and Verication Manual for the system master (for example, HP 70900B Local Oscillator).

System-level testing of systems controlled by an HP 70900 local oscillator can be accomplished

in two ways:

Run the system operation-verication tests, using revision C.00.01 or greater.(For system

operation verication, refer to the Installation and Verication Manual for the system's

master.)

Run the HP 11990A system tests, using revision C.00.01 or greater. The HP 11990A software

and documentation are available through Hewlett-Packard Sales Oces.

Troubleshooting

This chapter contains information about HP 70620B and HP 70621A front-panel LEDs and a

listing of the error codes for the HP 70620B and HP 70621A. The information in this chapter is

designed to help determine whether an error is being caused by the preamplier (HP 70620B

or HP 70621A). For more detailed preamplier troubleshooting information, refer to the

HP 70620B/HP 70621A Preamplier Service Manual
