HP3335A Synthesizer/Level Generator


My 27 year old HP3335A fails the spurious specification (-75 dBm) at +/- 60 Hz by about 5.5 dB. Probably needs power supply work.
It still meets the harmonic distortion specifications by at least 7 dB. ( <-45 dBm between 200 Hz and 10 MHz; <-40 dBc between 10 MHz and 80 MHz)
