How quickly are you triggering it?  If it is 10Hz or less you may be able to just have a periodically processed record to read the value.   That forward links to the record that clears the buffer.  You don't do this in the protocol file, but rather in the database.

With StreamDevice you can also set the record that reads the value to SCAN=I/O Intr.  Then it will poll for a new reading and whenever it gets one it will process your records.

If the triggering is very fast then you may need read a block of values into a waveform record.

Subject: stream device with Keithley 2410

Hello all,

I am trying to perform source (I or V) sweeps  and measure the sense values. The sweep needs to run an infinite amount of times (for the keithley source max is around 1e38 times ). This I can do by setting the trigger arm count. However I need to perform measurements during the sweep which I am having trouble with. Also I need to clear the buffer during this sweep cycle.

So my question is this. Is there something similar to  goto or an if/else that i can use in the protocol file to achieve this i.e read measurement-> clear buffer-> repeat, after the sweep has started.

Any help would be greatly appreciated.

Thank you

Regards,
Ali
