All,
I've come across a new (to me) oddity involving GPIB communication between
a Keysight/Agilent E5810A GPIB to ethernet bridge, and a Keysight/Agilent/HP
3458A DMM. I'm contacting Keysight support, but thought I'd see if someone
had already run across this issue.
It appears that the DMM is receiving commands which I send.
"BEEP" makes the DMM beep. If I send an invalid command I can
read the error message through its front panel.
However, valid commands which should send a reply (eg. "ID?") don't
trigger an error, but also timeout without sending back any reply string.
I see the same behavior with a second 3458A. Also when sending commands
directly through the embedded web server in the E5810A or a python vx11 client.
I tried two different GPIB devices (Keithley and Datron DMMs) with the same
E5810A and cable. Both send back replies and otherwise behave as I expect.
Thanks,
Michael
Also, a random fact for Friday. I was on a flight from JFK to LHR
which was listed as 3458 miles.
