Help! Does anybody have any information on the ITC SA500 scope adapter that converts a oscilloscope to a spectrum analyzer.  They were produced in the early 90s Any help would be appreciated  Thanks

Hi Joe,
Can't help you out on that one but it brought back memories of an earlier kit I saw.  I think the name of the firm was maybe Science Workshop.  I remember seeing them at Dayton back in the early 80's.  I believe it used old TV tuners or something.

Old VHF TV tuners are good for about 45-450MHz, with the UHF tuner covering the most of rest pretty well. In the 1980's I built a complete instrument with the tuners from a VCR in an old logic analyzer cabinet and re-purposed the magnetic deflection CRT by turning the yoke so that the vertical coil gave horizontal sweep, subbing an inductor for the H coil, and driving that coil with the video signal (pips) through a current amplifier. It's not calibrated in any meaningful way but has its uses and was a fun thing to make.
