Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
To the best of my knowledge, this is the only time this particular piece of software has shown up. Now is not the time to be experimenting.

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
I'd try and get hold of a parallel floppy.drive and if still no joy try and
use an old.tool called spinrite on it back in the day I had success
recovering data from floppy drives when all was lost.

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
No, this is NOT an option. A USB-connected floppy drive does not allow register-level access to the floppy controller; in fact the required registers aren't even present. Such access is generally

Re: E5071C Port Coupler Issue?
For future reference if anyone is interested, the part that was bad causing the wavy response (S11, S22) on these units was a burnt out switch a little further down in the chain ( *1GC1-6234* ).? It

Re: What kind of chip is this?
I looked up that HP83732A. Looks like only the rough info is included in the manual, but from the specs and block diagram it seems to be a very nice instrument. It covers the whole 1-20 GHz range with

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
The disk is most likely in LIF format so your Windows machines won¡¯t recognize it. Best recommendation is to get it to Dave McGuire as he¡¯s volunteered to make it available to the public.

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
Two things come to mind:
1. One can purchase USB-connected 3.5" floppy disk drives; if any of your
XP boxes have USB ports, this is an option.
B. If you have access to a *UX box (Linux, Solaris,

Re: What kind of chip is this?
I¡¯m thinking it¡¯s a directional coupler with a diode detector in the
coupled leg.
You should be able to inject RF power into the line with the transmission
line and see a proportional dc voltage

Re: Test Set Program Development Tool DEV_PL on 3.5" floppy
Wow. It is definitely worth pursuing. I hope Windows didn't do anything to the disk. A USB floppy drive won't work for something like this. If you are willing to send it to me, I can image it

Re: What kind of chip is this?
Do you know if it's actually bad? It should be easy to test - just put some in-band RF power (say +13 dBm) through it into a terminator, and look for some DCV at the detector output pin. Then swap the

Re: What kind of chip is this?
I only need the small opened part, not the rest. It simply unplugs from the rest of the module.
