Yves Hi again, I'm amateur electronic engineer (Hobby engineer) so In my work time I'm thinking manual case's of working conditions etc. So I forgoted the A8TP11 at 10MHz A8TP6 is 2.363Vdc A8TP11 is?

Hi Yves, I have made some measurements Q1 is not sorted or defective, R1 ( 155 Ohm power resistor) is ok too. The temperature in the A9 heat sink is 43 C in 15 min of working. A8TP6 of the not working

Any ideas?

Hi John, Here are some measurements on the Yig Oscillator PCB. It is possible that the YIG of 83595A and 83592A is the same. Setup: PRESET, start 2.3GHz/stop 7GHz. Oscilloscope triggered with signal

Thanks for the time you have spent on my problem The correction loop my produce extra heat on A9 heat sink ? Because it is extra hot after some time.

I recall there was more to it than just the capacitors. I reversed the design, quite a long time ago, and this is what I came up with... I cannot remember if I got any clues from the internet, but I

No, they are simple BNC that are bolted to a common faceplate. No transformers on the output, no isolated BNC etc. Wilko

Hi, I have some experience with the 8350B, as I have three plug-ins including an 83595A that I have repaired with some difficulty. There is the YIG OSC signal that is coupled and outputs on the rear

Thanks i'm gonna try that, i did not check that. I'm actually from France, where those are even rarer. I've been looking at spectrum analysers online for more than a year and i never came across a

Here is a video of the 100MHz calibrated signal going into the input of the attenuator. Does this look correct? https://youtu.be/Irq7qqfU4XA

New attenuators in use and unless I totally misunderstand how the 8566B is running things, that's not a constant step in attenuation. Thoughts? https://youtu.be/RpouDlm22IY

Hi Dave, Sorry, I was rushing to dinner earlier and missed part of your question. Settings on the SA (8566B) were 3 GHz center frequency, 2 MHz span, RBW 30 kHz, VBW 100 kHz, sweep 20 msec, 10 dBm

Yes, having a spare parts box may not be a bad idea. Here in the U.S., the 8568A/B is almost unwanted. It seems from your posts that you are in the UK, AU, or NZ. It may be harder to find a cheap

Hi Dave, Thanks for your reply, and great question! The span was approximately 170 KHz between spurs. I did the MW Calibration and no change. I took the A14 assembly (GaAs divider, MW Loop,

I 100% agree with you, that's not something i'd like to do, i personally wouldn't have thought of doing that. That's what the seller told me so i tried it too. Pushing on the INSTR PRESET button can

I guess that refers to a past topic/thread in this groups archive. The "Reference" is the neon tube, replaced by solid state parts. Dave B (UK)
