Hp 70000 system 50KHZ-22 ghz spectrum analyzer 70905A
This item has TESTED by our on-site Lab Technician and it works well. Please review the lab photos
below for additional information.
Lab Notes: Frequency coverage 50 kHz to 22 GHz, no preselection. The precision frequency reference
10 and 20 GHz frequency response checks were performed using a leveled generator and a 4 foot long
semi-rigid cable. The 300 MHz test was performed using the calibrator signal from the 70900A with a 6
inch cable. The system passes self test and self cal.
System consits of the following:
HP 70905A RF Spectrum Analyzer Plug in
HP 70900A Reference Oscillator
HP 70902A IF Section Res BW 10 Hz to 300 KHz
HP 70310A Precision Frequency Reference
Various Interconnect cables and Jumper for this configuration
The 70905A RF Section provides broadband input conversion for spectrum analyzers, lightwave signal analyzers
and other systems. It is a broadband low noise mixer for high dynamic range of 70 dB with a 10-dB-step attenuator.
It has a frequency range of 50kHz-22 GHz. It occupies 1 slot of the 70000 Modular Measurement System (MMS).
The 70905A RF section contains an input attenuator and a mixer. The RF mixer converts the incoming RF signals
to the intermediate frequency (IF) for further processing. The broadband, low noise mixer offers the performance
needed to make high dynamic range measurements. The input attenuator can be automatically coupled either to
the reference level for mixer protection or to the highest mixer level to maximize dynamic range. The input attenuator
varies from 0 to 70 dB in 10 dB steps. 50kHz-22 GHz broadband input conversion.

Probe connection on the front panel
The HP / Agilent 70900A Local Oscillator Module provides a swept LO signal of 3.0 to 6.6 GHz, processes video
signals, and acts as master controller for the spectrum analyzer. It contains the system firmware to control and coordinate
measurements and to output data. The 70900A has a minimum 32K bytes of memory for DLPs. For use with the 70000
series modular spectrum analyzer mainframes.
The HP / Agilent 70205A Graphic Display is a 3-slot wide module that is ideally suited for applications in which space,
size, and weight requirements are stringent. It is small yet gives full control of the modular instruments in your system.
Softkeys organized in a menu structure establish an interactive front panel for the modular instrument. Results from up
to four independent measurement systems may be shown and simultaneously updated on a single display, and one
display may be used to control multiple systems. Without a display in the system, a computer must be used to control
the instruments. The display can be separated from the MMS instruments by up to 1 kilometer of MSIB cable for use

The HP 70902A provides narrow resolution bandwidths, from 10 Hz to 300 kHz and can be used in any of the
The HP / Agilent 70902A IF Section I cmaximizes measurement speed using 10% incremental bandwidths. Wide
bandwidths offer the most speed, whereas narrow bandwidths offer more resolution and sensitivity. The 10% incremental
bandwidth steps offer you the best choice of bandwidth sizes. The bandwidths can also be changed in a 1, 3, 10 sequence.
Calibrated logging amplifiers provide superb amplitude accuracy for the analyzers. The 3 MHz IF output on the Agilent
70902A allows connection to other instruments such as demodulators, digitizers, and oscilloscopes.

The HP / Agilent 70310A Precision Frequency reference, a 1-slot wide plug-in module for the Agilent 70001A
mainframe, provides precision reference signals for use by Agilent 70000 systems and other instruments. System
frequency accuracy is enhanced because the 10 MHz and 100 MHz reference signals provided by the Agilent 70310A
are phase-locked to an internal ovenized oscillator, resulting in excellent stability over both time and temperature. With
a highly accurate and stable reference in your system, you can find signals more quickly by tuning to very narrow spans.
Option 002 deletes the ovenized oscillator and the accessory power pack from the Agilent 70310A, but retains the
external reference input capability. This is a good low cost solution if you plan to connect a house standard or other
external reference permanently to your Agilent 70000 modular spectrum analyzer.
The HP / Agilent 70001A provides the structural environment for MMS plug-in modules as well as cooling, power, and
digital communication interface buses (MSIB and GPIB). It has eight slots available for single or multiple-slot modules.
It is compatible with standard EIA racks, and its integral bails and handles make benchtop use easier. The mainframe
has good EMC performance and rugged structural design, making it suitable for sensitive measurements in tough industrial
environments. The modular system interface bus (MSIB) provides high speed digital communication between MMS
instruments, modules, and displays connected in the same system. The MSIB allows simultaneous communication
between all modules on the bus. The Agilent interface bus (GPIB) is used to provide computer control and communication
between MMS instruments and other GPIB instruments, including VXIbus products.
