Hello all!
I am looking for help troubleshooting an error I am dealing with characterized by an EDVR error and Ibcnt set to 0xE00A008B.
Background:
I am writing a program in C which calls to NI 488.2. The program is intended to read data from our HP 4155A, collect the data, and write it to a text file in csv format. I was successful in reading data strings from the HP 4155A using a read buffer of size 100000, but when I change the read buffer size to 1000000 ibdev fails to address the HP 4155A and I receive the aforementioned errors.
I referenced the NI 488.2 documentation page and found the entry on troubleshooting EDVR errors using Ibcnt but none of the Ibcnt values match mine.

0xE00A0047 is close (in numeric value) though I have no idea if that's relevant.

Thank you to any and all who have the knowledge to help here 🙂
