Randy, Is there a version number at the top of the file? I had two versions (1.00 and 1.01). I can't remember all that changed between the two since it has been a while but I did find an additional timeout code that limited the wait time for reading data to 1 minute. I am guessing I had a problem with mine and added it.
I can email it to you if you want to try it. If it works for you, I will have Illya update it on xDevs. Todd On Sat, Dec 30, 2017 at 12:39 AM, Randy Evans <randyevans2...@gmail.com> wrote: > I am still unable to get my HP-3458A to work with the xdevs program > "HP3458A_Measure_DMM_Noise.488" (https://xdevs.com/article/dmm_noise/). > It > works fine with my Agilent 3458A and with a friend's HP-3458A and his > Agilent 3458A using the EZGPIB program.
