CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

HP 140A and 141A oscilloscope power supply issues
Hi folks, I'm in the process of attempting to repair two older oscilloscopes - one is an HP 140A and the other is an HP 141A (its storage tube "brother" version). My 140A frame has serial prefix 546

Yes, my conclusion also (unfortuantely). I did find a replacement YIG (not cheap) but I still have the original question regarding the pretune constants setup when I replace it.

That makes sense. I would assume that at least early LCD panels used a CCFL lamp as a backlight. It may be possible to retrofit LEDs on such a unit.

Re: HP8753C Source Pretune after YIG replacement
The voltages are OK but there is NO outut from the YIG. I see the 3.8 GHz signal (+10dbm) from the cavity oscillator but absolutely nothing from the YTO.? If it's no the YTO what else could it be?
