Hi guys, just scored a cheap working 3478A. And after failing to write program to talk to the gpib I stumble to this program. Now I need some help because it seems that the gpib is only somewhat working (this is definitely the reason i fail to write the program... not my programming skill....
)
If I use this beautiful program, and set my gpib address at 6 (seems to be the value of the setting for the software as downloaded), it can somehow connect to the multimeter. I need to press the reset button, and then i can press the start button and get it to read the measurement and display it on the software.
During start up the software recognize the com port and set it correctly but will fail at detecting gpib.
If I press reset, it will say comm failure, but I can hear clicking in the multimeter, and after this if i press start button it will display correct measurement.
If I try to read cal data it will say comm fail.
If I set my gpib address to anything other than 6 I can still hear the multimeter responding when I click reset, but it will not allow my to start and will only show comm fail.
Any pointer as to where I should look at ? Or way to test the gpib ?
Thanks a bunch...
