Timeout Error when Reading Measurements from Impedance Analyzer Solartron 1260 via NI MAX using IEEE 488/GPIB

Abdul
Abdul over 1 year ago

Hi, 

 I'm working with a Solartron A1260 Impedance/Gain-Phase Analyzer and attempting to read measurements on the NI MAX interface connected through a PCI bus. The analyzer itself is functioning correctly and can receive "Write" commands, as you can see the measurements on blue screen, but when I try to "Read" these measurements using NI MAX, I encounter a timeout error, as illustrated in the attached screenshot.The only command I can read is `*IDN? `. but my goal is to "Read" that simple measurement data of impedance analyzer on NI MAX interface.

I have tried adjusting the timeout/Bytes settings and reviewing the connection, but the issue persists. It seems like the main challenge is that I'm not sure about the correct commands to read the measurement data. Here are the details of my setup:


- Device Model: Solartron 1260 Impedance/Gain-Phase Analyzer
- Connection: Interface through PCIB
- Software: NI MAX
- Issue: Timeout error EABO during GPIB read operation

- Troubleshooting Steps: Adjusted timeout settings, adjusted bytes, changed addresses, checked GPIB command syntax, changed GPIB

 I would greatly appreciate any advice on the proper GPIB commands for reading measurements from a Solartron 1260 or any troubleshooting steps that might resolve this timeout error.

Thank you in advance for your help!

    I read the paper. Very useful to learn / understand a working conversation for this brand. Warning to Abdul , at the end of the paper, the writer explains how one of his scripts damaged the instrument…

    You could also check for code for other Solartron products of that era, in case you can spot any difference. For instance, a student used a 1260A here: https://www.slideshare.net/JosephHaystead/enel301…

    What query do you send before the read attempt?

    • SI? ( stands for Single measurement) but gives me an error response.

    Launch NI IO Trace, set that running then send the command and see what the trace tells you.  I presume SI? Is from the manual?  If you don’t have that, here’s a link: https://mmrc.caltech.edu/Solartron/Solertron%20manual1260.pdf.  I suspect a handshake issue.

    Yes, SI command  is from the manual .Thank you for your prompt response and proposed solutions. I will thoroughly analyze them and provide an update tomorrow.
