The HP8642A and HP8642B synthesized signal generators are high performance programmable signal generators intended for the most demanding out-of-channel RF receiver measurements and other stringent RF applications. The HP8642A covers the frequency range from 100 kHz to 1057.5 MHz and the HP8642B covers the frequency range from 100 kHz to 2115 MHz. The two generators are otherwise very similar.
Low SSB Phase Noise
The HP 8642A/B improve the state-of-the-art in SSB phase noise at typical receiver adjacent channel spacings over the cavity tuned HP8640B signal generator. This improvement is made possible through the use of high-Q Surface Acoustic Wave resonator oscillators operating near 800 MHz. SSB phase noise 20 kHz offset from a 1 GHz carrier is -134dBc/Hz, approximately 6 dB lower than the HP 8640B. The HP 8642A/B are an ideal choice to characterize selectivity on high performance receivers up to 1GHz or 2GHz. Furthermore, their advanced control features simplify measurements on the bench and in ATE systems.
-100 dBc Spurious
Nonharmonic spurious are held to below -100 dBc on the HP8642A/B above 1GHz and to below -94 dBc on the HP 8642B above 1GHz. These two generators allow receiver spurious rejection tests to be fully automated with the utmost confidence in test results. In the HP8642A/B design, high performance mixers reduce typical synthesizer spurious, and rigid die castings with resilient RF gasket-ing provide up to 140 dB of circuit isolation to ensure low spurious content on the output.
Up to +20 dBm is available from the HP 8642A/B to perform a variety of high level measurements, often eliminating the need for external amplifiers. In receiver design, there is sufficient output power to drive high level mixers and perform receiver blocking tests. Intermodulation measurements can be made with high confidence since intermodulation distortion products on the HP 8642A/B are specified.
