Timing Issue - Waveform/XY Graph Data from Keithley 2100 Multimeter

[cstorey]

Hi Megan,

Have a look at the following example.  Before running it make sure the VISA resource is correct for your instrument.

The program poles the instrument for a single measurement, then waits a specified interval and repeats.  That interval can be 0s, then you will know how fast the instrument is capable of repeating measurements with the given setup.  I've made no attempt to look at instrument settings that would speed things up, you'll need to do some reading of the manual to see what the K2100 has in terms of settings.  There should be an auto-range, auto-zero, settling time, NPLC, etc.. that can be modified to make a measurement faster at the expense of accuracy.  Unfortunately, I don't have a K2100 for testing.

Note there are 3 termination conditions; stop button pressed, error from instrument, or a maximum time has elapsed.  You could remove any of those you don't want to use.

Let me know how it works.

Craig
