HP / Agilent 83595A RF plug-in provides a 10 MHz to 26.5 GHz broadband coaxial swept

The HP/Agilent 83595A is a broadband coaxial swept frequency source plug-in for the Agilent 8350B mainframe, delivering 10 MHz to 26.5 GHz coverage across five bands. This RF source excels in scalar network analysis, local oscillator applications, and standalone signal generation, combining wide frequency sweep capability with narrowband precision tuning.

## Key Features

• Single-plug coverage from 10 MHz through 26.5 GHz eliminates band-switching complexity
• Fine frequency resolution and CW accuracy support precision measurement and calibration tasks
• Integrated leveling maintains constant output across broadband sweeps
• Multiple modulation modes—AM, FM, phase lock, and pulse—enable diverse signal conditioning
• Low harmonic content <−20 dBc ensures clean spectral characteristics

## Typical Applications

• Scalar network analysis across S-parameters
• Down-converter local oscillator for superheterodyne receivers
• Stimulus source for broadband RF system characterization
• Signal generation for component and subsystem testing

## Compatibility & Integration

Operates exclusively as a plug-in module with the Agilent 8350B sweep oscillator mainframe, which provides power, control interface, and display functions.
