We have owned several GPIB-USB-HS for about 10 years.
Recently (around October 2022), I purchased two more.
A communication error (GPIB bus error) occurs between these two units.
Power supplies and measuring instruments work normally, but only communication using SRQ results in an error.
We have used over 30 units (GPIB-USB-HS and GPIB-USB-HS+) and have never had an error like this before.
The "PART NO" is different for the two units that cause the error.
Originally I was using 187965H-01L.
The two units with the error are 187965G-01L.
I think the SRQ of 187965G-01L is defective.
Could this problem be the two GPIB-USB-HS being faulty?
We would like your advice.
GPIB-USB-HS is purchased from a trusted distributor in Japan.
PART NO: 187965G-01L
