HP 85685A RF Preselector Need CLIPS and Software

(1/3) > >>

rastro:
I just acquired a HP 85685A RF Preselector for my HP 8566B spectrum analyzer.  I have located 2 documents on line but I'm looking for additional information. 

It appears that a portion of the system verification and almost all adjustments must be done via GPIB.  The PDF copy of the operations/test/adjustments  manual refers to BASIC program that is on a software disk in the front of the manual to run most of the procedures.  Unfortunately since my only manuals are PDF's I don't have the software disk.

I found 2 PDF Manuals:
1. 85685-90003   85685A Preselector Operations, Tests, and Adjustments Manual (missing software disk)
2. 85685-90098   85685A RF Preselector Operating and Programming Manual (Does not have any GPIB commands for maintenance)

What am looking for:
1. The software disk or BASIC program that goes with the 85685-90003 manual.
2. The schematics and/or service manual for the unit.
3. A more comprehensive list of GPIB commands that cover accessing internal functions or registers.

What I have done to date:
- Checked HP/KS site but the is little there.
- Checked http://artekmanuals.com/.  They didn't have anything; left a message but haven't heard back.

Any help is always appreciated.

rasto,
The basic program was contained on a LIF floppy disk  written in HPBasic and was intended to be used in a HP instrument controller system (i.e. HP9825).  The floppy can not be read by any modern computer system and so would not do you much good if you could obtain one.  The floppy was also protected such that a hard copy of the program could not be printed out.

Hello Herb,

Thanks for the insight.
I suspected that the floppy containing the BASIC program might be in LIF format. 
However I don't completely agree with you that I a pointless effort; I would still like to get a copy or image. 

My basic approach:
Try the LIF to DOS format conversion to see if can glean any information.
Investigate an HP9825 emulator which may solve the problem altogether.
Find an old controller so I can eves drop on the GPIB communications to derive commands to the preselector.

LIF to DOS Please refer to:

HP9825 emulator:

Ultimately I need to get is a print out of the BASIC program service routine so I can understand how to access and control the internals of the unit via GPIB. 
I suspect that I'm not the only person looking to extract software/GPIB service routines for checkout and maintenance on other vintage HP equipment.

Have you posted to the HP-Agilent-Keysight-equipment group on groups.io? If not I'd recommend asking there , hopefully someone has an image of the floppy stored.

I'm a member under the yahoo groups.  You just motivated me to finally logon to the new system to post.  Done.

I wish the new site had filter for only unread threads.
