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

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"
the output console and then just sits there.

I have not written anything else for the 3458A using EzGPIB. If you

If you are reading the temperature from the HP meter, I would think
the problem lies in how the triggering is configured. The triggering

additional
command added for disabling the buffer.
The code can be posted here, if possible or I can email it to you

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
interested in seeing if anything other than KE5FX's memory dump
will work on my HP3458A.

Randy,
I found the Prologix adapters and have modified the code in the
script. I am doing a test run now and will post the script when I

Todd,
I have swapped cables, moved the Prologix adapter to both meters
works, HP doesn't), tried Martins code as well as Xdevs's. I
tried another PC yet, maybe the next step.
Here is the code that Martin modified for two meters, as well as
modified Xdev's code per your directions (V1.02).
Thanks,

I will continue to look for my adapter. I haven't used it for
while.
I have seen similar issues and swapped cables, moved the
other meter, etc... One of my cables was bad from one side of
to the other (on the same end of the cable) and caused me lots
time. Weird reading errors were happening.
Would you email me Martin's code so I can test it here and I
anything can be done to replicate your issue.

Does it matter where I put the line in the Init_Device
procedure Init_Device;
begin;
EZGPIB_BusWriteData(gpib_address,GET_ID);
if EZGPIB_BusWaitForData(gpib_
address,meter_id,Timeout)
EZGPIB_ScreenWriteLn(meter_id);
EZGPIB_BusWriteData(gpib_address,TRIGGER_SOURCE);
until meter can be setup
EZGPIB_BusWriteData(gpib_address,'INBUF ON');

EZGPIB_BusWriteData(gpib_address,OUTPUT_FORMAT);

Randy,
I am the person that wrote that EzGPIB script. It was my
moved on to Python and I have only written a couple for
meters I have on hand. Version 1.01 is the most current
the 3458A.
I see that I should have added at least one more command
initialization. The additional init command is used in
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
find it, I will also test it. I want to make sure there
issues.
Also, do both meters run the same firmware versions? I
meter is using a much older version.

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

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.

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.

I will continue to look for my adapter. I haven't used it for
while.
I have seen similar issues and swapped cables, moved the
other meter, etc... One of my cables was bad from one side of

time. Weird reading errors were happening.

I am the person that wrote that EzGPIB script. It was my
moved on to Python and I have only written a couple for
meters I have on hand. Version 1.01 is the most current
the 3458A.
I see that I should have added at least one more
initialization. The additional init command is used in
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
find it, I will also test it. I want to make sure there
issues.
Also, do both meters run the same firmware versions? I
meter is using a much older version.

Since the KE5FX NVRAM download software works, that would seem to indicate
the GPIB is working, wouldn't it (download completes and checksums OK)?
Randy,
I think you need to consider electrical issues now.
GPIB buffer chips live a tough life, and they can fail or go frail
in so many weird ways that it is not even funny any longer.
The bad thing is that the problem may not even be the buffer chip
in the instrument you are talking to :-(

Randy,
Check that your firmware version on the Prologix is up to date. The latest
USB version is 6.107. You can see it in the Prologix GPIB Configurator
utility that can be downloaded from a link on their website.
http://prologix.biz/resources.html
I have uploaded a pic of my settings shown in the utility.
