Ive downloaded the drivers for the , im just programming the now and triggering the manually. I now know enough to know that I have no clue about anything at all. After exiting the loop, set the excitation to a safe value probably zero and do any other end of run housekeeping before ending the program. Im doing a current sweep from 0mA to. Next, have you actually verified that the instrument is set to address 14? My experience with Keithley GPIB Vis has been that they are useful in that they contain the code for most commands but their style and performance leave a lot to be desired. Message 3 of 8.

I do not have the instruments so I cannot actually test it. We apologize for any inconvenience.
Message 7 of Write in low current. A state machine architecture is an excellent way to handle test like this.
You did not give enough information. Government regulation, Tektronix is required to review all software download activity.
In any case, you should only two different GPIB addresses to choose between. It is supposed to be easy, but getting all the instruments to talk to each other and to the computer often takes patience and some detective work.
