Re: HP 3457A FET Transistors
Sure. But while I own a 3457A, I've never had to repair it, so I can't help you with your FET issue. It was frustrating, actually. I bought it on eBay as "broken", wouldn't power on, and got it very

Re: 8340B with apparent phase lock problem #photo-notice
Hello, Not even a cent perhaps, but I had intermittent phase lock issues on my 8341A. It turned out to be a bad cap within the 200-300 MHz VCO (C13 on A36). This was not immediately obvious from quick

After checking all voltages once again and connected the spectrum analyzer to the YIG output directly - the delivered YTO is definitly bad. Alltest will replace it. That's the good news. Alex
