Driver Functions
agb1500_measureBdv
id_query VI_TRUE (to perform system verification), or
VI_FALSE (do not perform system verification).
do_reset VI_TRUE (to perform reset operation), or
VI_FALSE (do not perform reset operation).
vi Instrument handle. This is VI_NULL if an error occurred
during the init.
agb1500_measureBdv
This function triggers quasi-pulsed spot measurement to measure breakdown
voltage, and returns breakdown voltage data and measurement status data. Before
executing this function, the agb1500_setBdv function must be executed.
Syntax ViStatus _VI_FUNC agb1500_measureBdv(ViSession vi, ViInt32 interval,
ViPReal64 value, ViPInt32 status);
Parameters vi Instrument handle returned from agb1500_init( ).
interval Settling detection interval. 0 (interval short) or 1 (interval long).
value Breakdown voltage measurement result. Returned data.
status Measurement status. Returned data. See “Status Code” on page
2-14. To disable the status data output, set 0 (NULL pointer)
instead.
NOTE status value after normal measurement
When the measurement channel performs the breakdown voltage measurement
normally, the channel reaches its compliance setting. So, the agb1500_measureBdv
function returns status=8 after normal measurement.
agb1500_measureIleak
This function triggers quasi-pulsed spot measurement to measure leakage current,
and returns current measurement data and measurement status data. Before
executing this function, the agb1500_setIleak function must be executed.
Syntax ViStatus _VI_FUNC agb1500_measureIleak(ViSession vi, ViInt32 channel,
ViInt32 interval, ViPReal64 value, ViPInt32 status);
Parameters vi Instrument handle returned from agb1500_init( ).
