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( ).
