HP 8657B RF Signal Generator 100kHz-2060MHz +13dBm-143dBm 001 Kinda Works-Parts

Manufacturer: Hewlett Packard HP

Model: 8657B

Condition: For Parts or Not Working. Comes in non-original packaging.  This unit is in fair cosmetic condition with lots of minor scuffs/scratches/residues from prior use.  The feet and one of the carry handles are missing.  The plastic tabs that cover the screws to hold the handle are missing also.
The photos show the exact item(s) the buyer will receive.

Notes: This generator is in PARTIAL working condition.  We were able to verify output from 10kHz (the limit of the generator) to 1.3GHz (the limit of our counter).  The keyboard responds to inputs, and the displays are clear and bright.  At high output amplitudes (especially >10dBm) the waveforms fall apart at low frequencies.  The sine starts to squish on top by 4MHz, and by 1Mhz there is a distinct shoulder on top.  By 100kHz the sine wave is more of a ramp, and at 10kHz it is both very badly distorted, and the output falls away to almost no amplitude.  The distortion goes away at lower amplitudes.  This unit can do both FM and AM modulation, but again these are badly distorted at low freuqueny/high amplitudes.   No other testing was done.

No manuals, cords/cables, or additional items are included if not listed or shown.
