In this video we take a look at an HP 8904A Synthesized function generator. I have been looking to grab a few of these for the lab to assist with alignment and calibration of FM tuners. This was also an incredibly stable function generator for the time and still to this day. With some of the built in modulation abilities it will be a welcome addition to the bench….. Once we fix the display issues.

** Repair exposes the Tech to mains electric and should only be done by trained personnel. Errors can be fatal. **
