Thanks for the responses, y’all.
I’m pretty new to this area of test equipment, and this is a hobby for me, not a profession, so my requirements could certainly be misinformed.
Budget is $200ish. Would prefer no computers be involved. I like the tactile interface of dedicated lab gear and the whole reason I need it is testing/calibrating/aligning other analog test equipment and older radio gear which I have gotten into because it’s NOT computerized or excessively automated.
Output level probably no more than 10-15dBm, don’t have a spec for phase noise, harmonic suppression as good as I can afford (I have a Tek spectrum analyzer that needs some attention).
Modulation AM/FM 1kHz tone, don’t need arbitrary waveforms or anything fancy like that.
I’m not sure I know what frequency agility means in this context. Like sweep generation?
I have been offered an HP 3325A, which probably exceeds my requirements for modulation/phase noise/harmonic suppression but only goes up to 20MHz, so my idea was to use it to modulate and sync an external likely DDS oscillator.
