VISA Write and Read taking a long time in-between Loops

Hi All,

So I'm having a really basic issue here, VISA Write and Read are taking a long time in-between loops. Setup: I am communicating with a Keithly 6485 Picoammeter using LabView, using a NI USB to GPIB adapter cable, using SCIP (488) commands.

Here's the measurement goal. Take 100 measurements, send them over, save them, rinse and repeat.

I mean the code is stupid simple at this point. The VI sets up the meter, Writes 'take a measure', then Reads the measurements sent, and then Loops over 'take a measure' and Read.

HERE'S THE PROBLEM: The meter takes 100 measurements in about 70 milliseconds, great, but time between loops is crazy long, in this case 60+ milliseconds.

I've tried so much. And read so so much. Please send help 🙂

Thanks!!!
