Re: How to display installed options screen on a HP 8920A

 

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 owners.

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 email to the seller.

What options would you recommend that the 8920A be fitted with if you wanted to work on HAM transceivers and homebrew items.

The one I have purchased comes with the following options :-

001 (High stability reference)
003 (GPIB / RS232 interface)
004 (Audio Signaling)
005 I believe this is a 512K memory upgrade
011 (CCITT Filter)
102 (Spectrum Analyzer)

In time, I'm thinking of swapping out 003 for 103 (GPIB / RS232 interface / Parallel)
Possibly also swapping 011 for one of the other filters, not sure which one yet.
The final thought would be up the power i/p from the standard 60W to 100W with opt 016.

For the moment I just happy I'll get my hands on a HP8920A

Best Regards

PS: I'll now have to look for "HP 11807A opt 100 (RF Tools)", instead of the "HP 11807E opt 100 (RF Tools)" I bought the other week thinking that I'd buying a 8920B later on.

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 the included options on the screen


If necessary I can dig out my HP8920A and photograph the procedure

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 options could
have been removed and the label left unchanged.
To be on the safe side, I want to see a photo of the installed on the
instruments display.

How do I instruct someone remotely on how to get display installed
options screen on a HP 8920A? (see attached photo of a different 8920A
from an ebay auction)
I just need to know the correct chain of key presses on the instrument
to get to that screen.

Best Regards
