The APSIN6000 portable RF signal generator specifies a phase noise -128 dBc/Hz at 1 GHz and a 20 kHz offset, harmonics of less than -40 dBc, and a resolution of 0.001 Hz from 9 kHz up to 6.4 GHz. An ...

This project originated from the need to produce a linear crystal-controlled ramp signal for an HP 8620C RF sweep oscillator. It is inspired by a previously published ramp generator design [1]. That ...
