Driver Functions

agb1500_setCv

Syntax ViStatus _VI_FUNC agb1500_setCmuInteg(ViSession vi, ViInt32 mode,

ViInt32 value);

Parameters vi Instrument handle returned from agb1500_init( ).

mode Integration/averaging mode. 0 (auto) or 2 (PLC).

value Coefficient for a reference value to set the integration time or

number of averaging samples. 1 to 1023 for auto mode, or 1 to

100 for PLC mode.

The reference value depends on the mode settings:

• For auto mode:

The reference value is the number of averaging samples that

is automatically set by the B1500. You cannot change it.

• For PLC mode:

The reference value is the averaging time (1/power line

frequency).

agb1500_setCv

This function specifies staircase sweep voltage source and sets the parameters. The

sweep source is used for the CV sweep measurement.

Syntax ViStatus _VI_FUNC agb1500_setCv(ViSession vi, ViInt32 channel, ViInt32 mode,

ViReal64 start, ViReal64 stop, ViInt32 point, ViReal64 hold, ViReal64 delay,

ViReal64 s_delay);

Parameters vi Instrument handle returned from agb1500_init( ).

channel Slot number of the slot that installs the MFCMU to be used. See

Table 2-2. channel=-1 detects the slot automatically.

mode Source output mode. 1, 2, 3, or 4. For the log sweep mode, start

and stop must be the same polarity.

1: Single-Linear sweep

2: Single-Log sweep

3: Double-Linear sweep

4: Double-Log sweep

start, stop Start or stop voltage (in V). Numeric expression. start and stop

must have the same polarity for log sweep.

0 (initial setting) to ±100 V
