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 8590a spectrum analyzer
Thanks Alex , I'll try that when I get the power supply re installed tomorrow. I was wondering how to check that. What's the correct part number for that diode pack?. Hsms 2822 or something like that.

Connect the input to the calibration output and turn the corrections off. Is the main tone about -20 dBm? if it is significantly lower (say, -30) then most probably the mixer diodes in the first

Re: HP 5086-7906 YTO
A lot of them tune at 20 MHz/mA, so 100 mA may not have been enough. I'd crank the main coil current up to 200 mA and see if that makes a difference. -- john, KE5FX Sent: Monday, August 29, 2022 10:09
