Hello,
Im using an Agilent 34461A and connecting to my laptop via USB and using Labview 2018 on a Windows 10 machine. I downloaded the Plug and Play driver and using the example code for single measurement I timeout when I query. In NI max the same result. I downloaded the IVI driver and attempted to use it with my device. Timeout error after initial connection with NI Max and the example code. It is only when I restart the DMM with the USB connected that I can query successfully. There is a Windows 7 device running Labview 2017 that interfaces perfectly with the PnP driver and runs on initial connection with this device and I have unsuccessfully taken the driver from that computer and try to use it on mine.
I also have access to an Agilent 34405A that I use with a PnP driver on my machine that I have no problems with. I have looked across the forum and tried everything I could find concerning this specific device with no luck. I would ideally want the PnP driver to work but can also use the IVI driver. My USB ports are not turning off and stopping connection with the DMM. Any help would be greatly appreciated. I have attached a file with I/O traces and successful query results.
Note: I am using NI Visa 18.5 and the most recent PnP and IVI for Labview drivers for the Agilent 34461A
Also, recently I would connect after restart and it would go into a simulate mode where on measurement query it
would output very large values.
I would appreciate any help as to why this may be happening and thanks in advance
