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

Re: HP 5342A blowing fuses on switch on
Jack, I would check CR1 and CR2 (the bridge rectifiers) 1st. One might be shorted. Assume you have a DVM and know how to do this. (with the board removed of course) Mark

HP 5342A blowing fuses on switch on
My 5342A freq counter has started blowing fuses on switch on. I removed the A19 board which just left the filter, fan and oven transformer in circuit. No blown fuse and the fan runs. Replaced the A19

Re: 8566B attenuator removal
The sizes I¡¯ve seen for watches weren¡¯t 1/2mm cross section. They were thicker like 0.6mm (1.0 ID/2.2OD or something like that). The proper size isn¡¯t that hard to come by.

Re: 8566B attenuator removal
If the problem is with the o-rings (likely scenario), you will not be doing anything to the attenuator cards. You will not be removing them unless they have been overloaded. The cards are made of thin

Re: 8566B attenuator removal
Jinxie, I made a mistake, the 8566 attenuator has four sections, not three. I may have mixed it up with the 8568 attenuator. A 40dB attenuator card with good return loss to 22GHz is difficult to make,
