RE: How to use the status model on a 3706A
Yes, the status.condition register still had some bits at logic 1.<br> I am not exactly sure what solved it, but I believe that I missed the <code>keithley.send_end = True</code><br> Now it is working as expected. Thanks for the help.<br> <br> Kind regards, <br> Lars -
RE: How to use the status model on a 3706A
Hello Andrea, <br> <br> I just tried your suggestion, and it seems that if I load my TSP script into the 3706A up front, using a separate python script and the command <code>write('loadscript filename')</code>, it does not work.<br> <br> If I instead write the TSP script to the instrument line by line in the same python script that also trigger the measurement, like your example, it seemed to work for awhile. Now, suddenly, it is not possible to reset the status registers by use of <code>status.reset()</code><br> <br> Is there any ways of completely reset the instrument to factory defaults (the <code>reset()</code> does not seem to fix anything either)?<br> <br> <br> Kind regards, <br> Lars -
RE: How to use the status model on a 3706A
Hello Andrea.<br> <br> thanks for the explanation and suggestions.<br> I will try this as soon as I am in the lab on monday, and report back to you.<br> <br> Your help is much appreachiated!<br> <br> Have a great weekend!<br> Kind regards, <br> Lars -
RE: How to use the status model on a 3706A
Hello Andrea, <br> thanks for you quick reply.<br> <br> This is not working for me.<br> Also, I would like to understand this a bit better, as I find the manual a bit confusing. There is no SRQ annunciator on the front panel when running this on my instrument.<br> <br> Kind regards, <br> Lars -

How to use the status model on a 3706A
Hi,<br> <br> I am currently trying to set up a python script to get the results of measurement sweeps using a 3700A, but I cannot seem to get a correct understanding on how to use the registers to do this.<br> <br> I want to use the OPC() command to check if the measurements are complete, before reading the measurement buffer.<br> <br> <br> Could anyone help me understand how to do this?<br> <br> Kind regards, <br> Lars
