Hi Danny, You got that one for a good price. Our friends across the pond pay a lot more than $1025 :-) You should run the IODIAG2 test from the ROM tests list if it is present in your test set's

Glad you got it going.

Hi Daniel I should also say that the ONLY way that you can be absolutely certain of the frequency range of a HP8920A or a HP8920B is to measure it, so many changes to then have been made by past

Oh, it worked! It was a problem with the LM1881 supply. Thanks a lot, Ralph! ---8<---Corte aqui---8<--- http://www.tabajara-labs.blogspot.com http://www.tabalabs.com.br ---8<---Corte aqui---8<---

The SA and signalling option are the only ones I consider required. The high stability means longer warm up time to come on frequency and with the cheap availability of GPS locked references not sure

Hi Danny Do you know the first five characters of the serial number, Generally 8920A's manufactured before 1999/2000 have an electro-mechanical input assembly (attenuator) and will work down to

Hello George Thank you, you've saved me from heaps of digging through pdf's I think the instructions are fairly straight forward, so no need to dig out your 8920A. I'll just cut and paste them into an

Try this To check your installed options: 1) Press the “TESTS” button, 2) Select “ROM” under procedure location 3) Select LIST_OPTS under procedure 4) Select RUN 5) The HP8920A will now list

Here is what I did. ?While it does not have anything to do with it working, I used one of the DC to DC ?converters that takes any reasonable voltage and will lower it to a value set by a pot on the

Hello HP8920 hive mind :-) I am asking a seller to get me a photo of the installed options/firmware screen of an 8920A i have just bought. He has given me the options from the rear label, but the

Tried the GBS 8200 V4.0, CDMA service monitor E8285A. My results: - Composite video into the Y input...No signal - Composite video thru a LM1881 sync separator, video as G, HSync as Sync...No signal -

I'm waiting for my GBS card to arrive and test it. By the photos you need a sync separator, so I connected a LM1881 chip to extract h-sync and v-sync, and I'll test it on RGB input (as a MDA signal,

Hi, I see some very interesting photos? of the HP8924C with GBS8220 Video Converter. (mostly from wb7dmx and others, transferred from the old Yahoo! group) In some of them it seems the GBS8220 was

My experience with SRAM and Flash cards: I used an old Gateway laptop with WinXP. I could read/write an SRAM card just the same as if it were a drive. I could also read/write a Flash card that came

Hi Robert I think that we are both making the same point but using slightly different language. Somewhere I have an advertising flyer for the 8920A with splashed on the front page "New electronic

To repeat myself from the other group--- I have an 8935 RF gen goes down to 100KHz Wally

I made a longer post earlier but it does not seem to have been approved by the moderator yet. The A23 extended option list is in IODIAG2 (my not yet approved email said LISTOPT in error.) I've put a

Yes, that confirms that you have to check the individual instrument to be 100% sure. The information in catalogs indicate the 8920A should always have had a mechanical A23 module from new. I can find

The units with the relay based attenuator should also have the .4-1Ghz label on the front ..this is true for the A's and B's the early 8920A only had the relay based RF I/O? standard and the later

Hi Robert As I said I have little experience with the 8920B. The really confusing issue with the 8920A is the front panel which gives the range as 400KHz to 1GHz even when option 055 is not fitted. My
