Bill, I measured the time between SMPL symbols with NPLC set to 1000 and it is approximately 33 seconds. It takes an hour to complete 100 readings. Randy On Mon, Aug 25, 2014 at 10:01 PM, Bill Gold wpgold3...@att.net wrote: Not that I know of. Just wait and when you don't see a SMPL on the

hi randy, just for curiosity, why doing 100 measurements at nplc 1000. is this to sample a changing value? when i am doing 10 measurements from a stable signal at nplc 100 (only there many subsequent measuremnts with statistics make sense) I am already getting a stanard deviation below 0.1ppm.
