Re: [volt-nuts] GPIB Issue with 3458A

Todd, The routine looks like this on the Output Console: HP3458A 24.4 0 1 The 0 pops up after several seconds and the 1 after even more seconds later. No other output after the 1. The temperature reading is OK but no voltage readings. Thanks for the assistance but I likely have a

Re: [volt-nuts] GPIB Issue with 3458A

Randy, Check that your firmware version on the Prologix is up to date. The latest USB version is 6.107. You can see it in the Prologix GPIB Configurator utility that can be downloaded from a link on their website. http://prologix.biz/resources.html I have uploaded a pic of my settings shown in

Randy, I found the Prologix adapters and have modified the code in the original script. I am doing a test run now and will post the script when I am certain I didn't make it worse. Todd On Sat, Dec 30, 2017 at 7:15 PM, Randy Evans wrote: > Todd, > > I have swapped

Re: [volt-nuts] GPIB Issue with 3458A

Todd, I have swapped cables, moved the Prologix adapter to both meters (Agilent works, HP doesn't), tried Martins code as well as Xdevs's. I have not tried another PC yet, maybe the next step. Here is the code that Martin modified for two meters, as well as the modified Xdev's code per your

Re: [volt-nuts] GPIB Issue with 3458A

Randy, I will continue to look for my adapter. I haven't used it for quite a while. I have seen similar issues and swapped cables, moved the adapter to the other meter, etc... One of my cables was bad from one side of the connector to the other (on the same end of the cable) and caused me lots

Re: [volt-nuts] GPIB Issue with 3458A

Randy, I am the person that wrote that EzGPIB script. It was my first before I moved on to Python and I have only written a couple for the different meters I have on hand. Version 1.01 is the most current version I have for the 3458A. I see that I should have added at least one more command to

Re: [volt-nuts] GPIB Issue with 3458A

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

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. The SW versions are identical with my

I am hoping some of you experts might be able to assist with a strange problem i am having trying to make automated measurements using EZGPIB with an Agilent and an HP 3458A. I have a program given to me by Martin Reynolds, which is a variant on the Xdevs noise measurement program. Martin's
