Re: [SOLVED] HP 8594E - AMPTD CAL : GAIN FAIL FOLLOWED BY "CAL SIGNAL NOT FOUND"
Without knowing, I was using a 75 Ohm N to BNC adapter which was ALSO defective. CAL routine is now successful.

Re: What would happen if I let the battery in my HP 54622D oscilloscope run down?
I understand that bit. On the HP 3478A DMM replacing the battery without maintaining voltage in the circuit caused loss of calibration and you have an inaccurate meter. If I just remove and replace

Re: HP Diode ID Help
Just some additional information The individual diodes for this pair are found under part number 5082-2303. H P crosses that diode directly to a 1N5167. 5082-2303 diode specifications: Minimum

Re: HP 8510 C with HP 8511B
Because control boards are same, it must be configured by switches at the A3 board. You can find proper settings there, at block diagrams (pages 49-51)

Re: Dead 54720D
Mike, could you explain how did you figure out that checksum bytes are at 0x48 and 0x7a ? Do you have any knowledge what thay represent ? Im preparing HW to get flash content from my 75412A and 75421A

Re: HP 8592B: 0hz peak is not @ 0Hz !
Hi Joel, were you successful ? I have a very similar issue with a known working 8594E. I reset the default CAL, ran the CAL with -37Hz, but the CAL routine never finishes and stay stuck at "CAL: EMI

HP 8594E - AMPTD CAL : GAIN FAIL FOLLOWED BY "CAL SIGNAL NOT FOUND"
Hi group ! I will start by saying that I really messed up here. I hope I will find help. I noticed one day that my Analyzer was not reading the right amplitude in the 100Mhz range. It did read the

Re: 8640B Scruffy and does jot tune Frequency
This fellow specializes in the 8640 and he rebuilds the frequency range gear assemblies. I don¡¯t have any connection with him except for buying a gear range assembly.

Re: What would happen if I let the battery in my HP 54622D oscilloscope run down?
If the battery runs down it will eventually leak and ruin the scope or DMM. I suggest you replace it.

Re: HP Diode ID Help
I think your memory is pretty good -- it's mine that is untrustworthy! But if the -2803 is indeed a matched pair of 1N5711 or 1N6263 Schottkys, it would serve well in those probes. --Tom -- Prof.

Re: HP Diode ID Help
I wonder if those are the diodes used in the 8405A Vector Voltmeter probes?? I used to change these out when they got zapped. -hp- supplied a little kit. Its been a lifetime since I saw any so my

Re: HP Diode ID Help
Those are Schottky diodes. Lots of uses for matched Schottky pairs, as you can imagine. IIRC those are basically 1N5711s. --Tom -- Prof. Thomas H. Lee Allen Ctr., Rm. 205 350 Jane Stanford Way

James bonjour, BRAVO, 8640B is a classic cavity resonator and still the lowest spurious and emission generator. We have three of these. Varios fine options: Add 512...1024 MHz band Add output reverse
