result[ ] Response from instrument.
count Count of valid items in result[ ]. Returned data.
agb1500_cmdInt32_Q
This function passes the cmd_str string to the instrument. This function expects a
response that can be returned as a 32 bit integer.
Syntax ViStatus _VI_FUNC agb1500_cmdInt32_Q(ViSession vi, ViString cmd_str,
ViPInt32 result);
Parameters vi Instrument handle returned from agb1500_init( ).
cmd_str Instrument command (cannot exceed 256 bytes in length).
