Re: [volt-nuts] GPIB Issue with 3458A

2017-12-30 Thread Randy Evans

Todd,

Since the KE5FX NVRAM download software works, that would seem to indicate
the GPIB is working, wouldn't it (download completes and checksums OK)?

2017-12-30 Thread Randy Evans

Todd,

The minimal quick test would be greatly appreciated if you have the time.
I know this is above and beyond what I would expect but it would be really
useful to see if there is any hope for the GPIB on this unit.  I will do
the service note 13 procedure in the morning.

Thanks again,

Randy

Re: [volt-nuts] GPIB Issue with 3458A

2017-12-30 Thread Todd Micallef

Randy,

Short of swapping out the A5 digital board I have no other ideas. If you
don't have a NI or Agilent adapter, I am sure I can find a spare for you to
test.

There is a Service Note 3458A-13A that deals with GPIB communication
failures. There is a test within the document to see if a shorting jumper
needs to be installed.
I can try reducing the code to something minimal for a quick test if you
want. It will take some time in the morning.

Same as before.  Still not working.  All it does is print out "HP3458A" on

Randy,

I just remembered that I changed the duration from 30 minutes to 2 minutes
to speed up the test. I forgot to change it back.

Randy,

I have not written anything else for the 3458A using EzGPIB.  If you have a
National Instruments or Agilent adapters, I have a handful of Python code I
use to measure some of my standards.

If you are reading the temperature from the HP meter, I would think that
the problem lies in how the triggering is configured. The triggering has
been changed in this script so it may work for you. There was an additional
command added for disabling the buffer.
The code can be posted here, if possible or I can email it to you for
testing.

Todd, thanks for the help.  Where will you post the new code? 
BTW, do you have any very simple code that is likely to work.  I am interested 
in seeing if anything other than KE5FX's memory dump program will work on my 
HP3458A.
Thanks again,

I found the Prologix adapters and have modified the code in the original

Randy,

I found the Prologix adapters and have modified the code in the original
script. I am doing a test run now and will post the script when I am
certain I didn't make it worse.

Todd,

I have swapped cables, moved the Prologix adapter to both meters (Agilent
works, HP doesn't), tried Martins code as well as Xdevs's.  I have not
tried another PC yet, maybe the next step.

Here is the code that Martin modified for two meters, as well as the
modified Xdev's code per your directions (V1.02).

Thanks,

Randy

Re: [volt-nuts] GPIB Issue with 3458A

2017-12-30 Thread Todd Micallef

Randy,

I will continue to look for my adapter. I haven't used it for quite a while.

I have seen similar issues and swapped cables, moved the adapter to the
other meter, etc... One of my cables was bad from one side of the connector
to the other (on the same end of the cable) and caused me lots of wasted
time. Weird reading errors were happening.

Would you email me Martin's code so I can test it here and I will see if
anything can be done to replicate your issue.

Todd

You can add it after the last line with the OUTPUT_FORMAT

Re: [volt-nuts] GPIB Issue with 3458A

2017-12-30 Thread Todd Micallef

Randy,

I am the person that wrote that EzGPIB script. It was my first before I
moved on to Python and I have only written a couple for the different
meters I have on hand. Version 1.01 is the most current version I have for
the 3458A.
I see that I should have added at least one more command to the meter
initialization.  The additional init command is used in the scripts on
xDevs.

Add the following line in the Init_Device procedure
   EZGPIB_BusWriteData(gpib_address,'END ALWAYS');

This tells the meter to send an EOI on every read.

I am looking for one of my Prologix adapters or I would test this. When I
find it, I will also test it. I want to make sure there are no further
issues.
Also, do both meters run the same firmware versions? I wonder if the HP
meter is using a much older version.

Re: [volt-nuts] GPIB Issue with 3458A

2017-12-30 Thread Todd Micallef

Randy,

Is there a version number at the top of the file? I had two versions (1.00
and 1.01). I can't remember all that changed between the two since it has
been a while but I did find an additional timeout code that limited the
wait time for reading data to 1 minute. I am guessing I had a problem with
mine and added it.

I can email it to you if you want to try it. If it works for you, I will
have Illya update it on xDevs.
