- ;- This assumes that you have instrument set to GPIB address 3.
- ; If you have an instrument in a different address change "GPIB::3::0" to the
- ; corresponding descriptor. Do the same for the call to _viOpen
- ; It shows how to use the _viSetAttribute. In this example we use _viSetAttribute
- ; instead of _viSetTimeout to set the GPIB timeout of a _viExecCommand operation.
