I have HP3456A and 3458A Multimeters. The AD card is AX5488, They worked very well before I moved their positioin. I checked the connection cable and I found that the 3456A worked well when it was connected to computer directly, but it did not work when connected with3458A ,even the 3458A was closed . Other devices connected to 3458A have the SYNTAX ERROR, include 3458A itself. The program did not change and worked well before I have moved them. Did you meet the problem and How to deal with this problem? Thank you!
