Verifying a Successful Configuration
An example C-SCPI (Compiled-SCPI) program source is shown on the
previous pages. This program is included with your C-SCPI driver tape (file
name verif.cs). The program uses the
*IDN?
query command to verify the
HP Scanning A/D Converter module is operational and responding to
commands. The program also has an error checking function (check_error()).
It is important to include an instrument error checking routine in your
programs, particularly your first trial programs so you get instant feedback
while you are learning about the HP E1313/E1413. After you run the C-SCPI
preprocessor and then compile and load this program, type verif to run the
example.
