I am using power supplies series E3610x with LAN Interface and trying to display a message on the display using the DISP:TEXT command. I've tried DISP:TEXT "Keysight" and DISP:TEXT 'Keysight'. However, all I'm getting back is the error message -151,"Invalid string data". Otherwise the communication with the power supply works fine, I can set voltage and read current.
This DISP command should be simple, what am I doing wrong here?
Thanks, Guenther
Hi Yves
thank you for your reply
There is a space after the :TEXT command
After your suggestion, I tried with USB and DISP:TEXT works just fine. Going back to LAN with the same syntax and I'm getting the same error message -151. Then I tried adding a CR/LF, but to no effect.
All other commands I'm using (APPL, MEAS, OUTP, STAT, SYST and also DISP:STAT) work just fine with the LAN Connection. Could it have something to do with the quotation marks, which are not needed for any other command I'm using? Is it possible they get changed along the way? Is there be any special interface setting I have to be aware of?
Thanks Guenther
Hi,
Unfortunately, I have no E3610x, I did a test on an E3634A that does not have a LAN connection.
I used the LAN to an E5810A interface (LAN to GPIB), then from there in GPIB to E3634A and it works well.
However I have a 34410A that has a LAN interface and uses the same TEXT command, and it works well there too.
I used IOmonitor (a utility that comes with IOlibraries) to see what is being transmitted over the network.
I can not see what the problem is, sorry.

Hi Yves
thank you for your support. I am beginning to suspect that this might be a firmware bug. I tried the only other command using a string CAL:STR. Same behavior, error -151
I hope Keysight is monitoring this forum. Any input from your side?
Thanks Guenther
Hi,
you have the right syntax, did you try with the USB connection. There must be a space between the :TEXT command and the first " or ' character. Do you use "Connection Expert" with IOlibraries to do the test?
