Agilent / HP 8644A

HP 86448 Synthesized Signal Generator

The HP 8644A Synthesized Signal Generator is a high performance, 252 kHz to 1030 MHz generator that provides excellent spectral purity for confidence in RF measurements. For R&D or stringent testing of communications equipment, the low phase noise and low spurious provide the measurement margin necessary for repeatability and accuracy. The HP 8644A uses a modular platform that allows you to configure the instrument for your application.

High Performance Modulation

For receiver measurements the HP 8644A offers AM, FM, and pulse modulation. FM deviations up to 20 MHz combined with specified rates to 100 kHz can test most communication receivers. AM performance includes 0-100% depth and rates to 100 kHz.

Advanced Internal Modulation Source

An optional internal modulation synthesizer provides four sources each with a frequency coverage of 0.1 Hz to 400 kHz and and sine, square, sawtooth, and white gaussian noise waveforms. Two of these sources can be summed together to provide two-tone capability, and one of these sources call be modulated by up to three of the sources with AM/FM/BM, and pulse. This source can also generate signals for testing VOR and ILS receivers.

Lowest Specified Leakage of Any Signal Generator

'The standard HP 8644A has typical leakage of < 1 uV induced in a two-turn loop, which is sufficient for most R&D or production testing.
