Re: HP8643A Displays Result Code 14.020122

Dear Mike,

I¡¯ve had that one.

It may be as benign as the back-up battery needs replacing.

When I first bought mine, which had not been used for at least some months, I would get this eror.

Then I found, after running it for some hours, I could switch off and then switch on a few days later and it would revert to previous settings, without going through the Calibrating¡­.. or producing an error.

It has settled down to going through calibration, but no error, if it is not used for more than a week.

Of course it is quite possible that there is a capacitor fault, but, for now, I am building up the enthusiasm for the weight lifting required to get the generator out of the rack, so that I can replace the back-up battery.

Regards,

Alwyn

Re: GPIB Adapter?

 

Yes. It was never intended for very high data rates as it polls the bus. Do you have the latest FW? There has been a number of improvements over the years. I have also been working on an updated FW that uses interrupts instead. It uses the same PCB, but a different processor
Re: HP8643A Displays Result Code 14.020122

 

Hey Mike,

My 8643A showed?14.020.116, which I deciphered to ¡°5.2V rail out of spec¡±. Turned out it was at 4.9V, and indeed out of spec. Recapping the PSU fixed it all up. Note that I looked for ripple and found none.

Re: GPIB Adapter?

 

AR488 has problems with EZGPIB and other software that wants full RS-232 handshaking rather than just XON/XOFF. There are workarounds documented in the manual. That's not a problem if you write your own software to drive it. But should be considered if you're not.

I am working with the author to add a number of features:

Real time clock
Temperature and humidity sensor
Relay control and in particular 44421A boards
External trigger output
Secondary addressing

He recently ported it to the ATMEGA 2560 and is now merging the two copies of the source. When he finishes that I'll start adding the features listed above which I am developing. I've got an Uno all set to read my pair of 34401As except for soldering the bus wires, but have been playing with various other toys, mostly an SD-24 head for my Tek 11801. I keep telling myself, "tomorrow I'll finish the AR488" but then I get to fooling with other stuff and at the end of the day it's still not done.

I will also be writing a Makefile with a test suite and verifying all the GPIB timing with my 16500. I'd viewed the ATMEGA with disdain for a long time, but it is 5 V TTL compatible and provides 40 mA of driver per pin. That's a bit short of the GPIB spec of 48 mA, but not by much. There's a lot to be said for a $3-9 board that will drive 10-12 devices using ribbon cable and IDC connectors. With several, a USB hub and a Pi or Beagle it becomes a pretty powerful T&M system.

I have two goals I'm trying to accomplish:

automate an annual full calibration of my electronics bench
monitor a bunch of voltage references for the purpose of studying aging behavior

Given my chronic ADD, I'm sure I'll find lots of other goals.

Have Fun!

Re: GPIB Adapter?

 



Hello, here I am using HP 82357B. it is very easy to use with HP's IO suite library. This libraries is free. This HPIB / USB adapter costs less than 80 euros and can drive more than ten devices. I use it in environment W7 and W10, if IO lib installed, eaysy to use with different languages. It works with HPVEE and Matlab automatically see HPIB interface. For C, C ++, C #, python, VBNet you need add librairies. Just a few lines of code to order and read a device. HP works with HP without problems and even with other manufacturers. I do not use LabView because I find it much more complicated than Matlab, especially for working in GPIB or RS232C.

Best regards and enjoys to drive old equipments...

Re: GPIB Adapter?

 

I also have two of and they work fine as long the data rate is low. I.e. I fail to get them working with my HP8753D and KE5FX VNA program. I suspect buffering could be improved in the PIC SW. But with other instruments like my frequency counter there is no issues.

HP 89410A (89441A) is stuck during bootup Help!

 

My trusty HP 89411A unit (rebadged 89410A) refused to start up today.?

It is stuck on the bootup screen with all keyboard indicator lights off and no response to keypresses. HP-IB connection is dead too.

Restarting with "Return" pressed does not seem to make any difference.

Any idea what the next test step would have been for a happy unit?

Re: HP 85044A T/R test set part - Cabinet Trim "zipper" - 08502-20007 - source or 3D printed copy?

This is *really* primitive, but I did make a clone of the 85044A zipper on tinkercad, and the export files are attached (tinkercad an Autodesk online service). I had a pair printed today at the university library (I'm a student there) at a cost for $3 for the pair, got them home, and pushed them into the 85044A case - they fit pretty well (just a little more insertion pressure needed than I expected, but still not too hard to adjust). The cabinet holds together without rattling and I suspect will be durable as long as I don't try to remove them again (at which point I suspect they'd break at the weak points described below.)

The design has a weak point along the length (every other tooth section in the zipper is a weak point, as using arrow keys to step-and-repeat the base pattern isn't accurate as tinkercad has no x,y,z coordinate editing capability so I had to do this visually). This weak point could be fixed by redoing the step-and-repeat perhaps to have each tooth section slightly overlap, but I'll leave that to a more experienced CAD designer.

The plastic the university library used wasn't as flexible as the original HP part (they had only one choice), but they do suffice to hold the cabinet halves firmly together, which was needed as the 85044A arrived without these parts at all.

The two files I attached are .stl and .zip (compressed .obj file); these appear to be the only export options on tinkercad, and I'm not sure if either of these files would allow one to import back into tinkercad and alter the design. I'm an absolute beginner at 3D printing and CAD (this is my first project); tinkercad (save for the absence of x,y,z coordinates for objects and object groups) is fully on-line (browser-based).

There are a lot of gaps in there. No coordinate entry capability?
Surely Autodesk knows better than that!

If you're of a programming mindset, you might look into OpenSCAD.
(it's free) Stuff like this would take just a couple of lines of code.

Re: GPIB Adapter?

 

When I started at NCR in 1988, my department (which was word rather than number intensive) had one of I think four in the world Convergent Systems "Worksaver" networked word processing systems.? There was a mainframe unit that provided shared file storage and a couple of back-end applications.

The server connected to 4 strings of up to 16 workstations which were 80186 or 80286 systems with floppy and sometimes small hard drives.?

This is related to the thread because I am pretty sure that network was GPIB, with fat multiconductor cables and daisychained connectors on each string of workstations.? At the time I wasn't familiar with instrument communications, so it didn't ring any bells with me.

The Worksavers were great word processors, with high resolution monochrome screens that could display attributes like bold, underscore, and italics.? It took a long time for PC word processors to become so nice to use.

Your story brought back an interesting thing that happened to me at U.S. Instrument Rentals. ?I got a call looking for a Fluke 8500 with GPIB. Not a strange request except the customer was Loveland Instrument division. I asked the engineer why did he wanted the Fluke and his answer was they wanted to test it on HP computers to see how it reacted. I think this why HP stuff always worked well

As many of you may know, HP started in the 60's with parallel bus interfaces of various types, like used on the 5055 recorder (and earlier 562 recorder, imagine a 4-2-2-1 nybble for the data instead of BCD 8-4-2-1) for data logging. As instruments began to have more "smarts" via SSI & MSI chips, custom bus structures for each instrument evolved to allow control. By the late 60's it got fairly sophisticated.
The HP 1000 Minicomputer (of which I have had several) had GPIO card to allow it to control instrumentation for data logging. (HP3490 DVM?? IIRC was one). I had a complete HP 8542A Vector Network Analyzer (.01-18GHz, $300K in 1968 dollars!) as well as an HP 8580 Automatic Spectrum Analyzer (same range) GPIO driven, custom interfaces on every box, many of the system components modified with H numbers for the custom digital interface (HP8410-H34 was the VNA M/F).
Living near the center of gov allowed me to attend surplus sales where I acquired a LOT of this early hardware, used it, now gone to gold scrap.

The desire for a standard instrument interface to facilitate software development and reuse of S/W led to the HPIB concept (1974 originally?) which became the IEEE-488 standard of 1978 after suitable evolution and IEEE committee agreement amount the various instrument makers. A 8 bit parallel, byte serial interface with dedicated control lines for handshaking. I remember having a lot of trouble making PC's with GPIB cards (BBB, NI, etc.) talk to various non-HP 488 stuff back in the eighties (Narda 2-18 GHz Sig Gen!). Once I bought my first of many 9826 Calculators ($1000.00 used, a princely sum then), all my problems went away. HP stuff spoke properly, right line terminators, etc.? Still love RMB to this day, although used HTB as well on PC platforms.? You guys have it much easier with "plug & play" these days. USB, wow!

I spent a lot of time with that old stuff as I couldn't afford new catalog items ! Made a bag of money using it to do real work though. Gave me capabilities that seemed like fantasy then, common now.? Learned a LOT. "Dems was the good ol" days!"

Brings back a lot of memories.
