I have an HP3330B and 3570A under GPIB control user an original program and an NI GPIB card.
This program operated properly until the cmos battery died when the computer was not used for 12 years.
The computer is up and running (Win 95) and the program ran properly one time. But I had no drive voltage because
of a missing cable, so the data was garbage. Now the program gets as far as setting the frequency of the 3330B and then
says 3570 type mismatch, the message is a little longer but I don't have my note and my memory is poor.
I have went through a section in the original program manual, ( by original, I mean we had a company write software to run the machines and collect data)
"Verifying Communication"
ibdev 0 4 0 11 0 0
Turns on the Remote lights both machines
and it presents with a ud0 : Prompt
Entering; ibwrt "L12.3=" causes the display on the 3330B to read 12.3 Hz
entering exit causes the remote lights to turnoff.
So Far So Good. The next commands test the HP3570A
Type ibdev 0 15 0 11 0 0 (enter)
This presents the ud0 : prompt
ibwrt "%" should TURN ON the Amplitude Offset light
It Does Not.
It returns [8100] (err cmpl)
error : ENOL
count : 0
The next command is to TURN OFF the Amplitude Offset light
Returns the same error.
Now just like the original program, these tests worked one time out of 25 or 30 tries.
Any ideas how to approach this problem?
