Information 1-1

Module Description

The HP 70620B and HP 70621A preampliers are 1/8-width modules designed to plug into an

HP 70000 Series mainframe. The preampliers are low-noise, high-gain amplication stages

to use in front of the RF section of any HP 70000 Series RF or microwave spectrum analyzer.

Refer to Table 1-1 for information about preamplier frequency ranges.

Table 1-1. Frequency Ranges

Preamplier Frequency Range

HP 70620B Option 001 100 kHz to 26.5 GHz

HP 70621A 100 kHz to 2.9 GHz

The front-panel +28 V dc output provides a noise-source drive voltage. This allows the

spectrum analyzer system to be used to make noise-gure measurements. Refer to Application

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.

\Module Options"

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

module. The preampliers are shipped with this Installation and Verication

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.)
