agb1500_setAdc
This function sets the integration time or number of samples that is taken or
averaged for the measurement. See also “agb1500_setAdcType”.
Syntax ViStatus _VI_FUNC agb1500_setAdc(ViSession vi, ViInt32 adc,
ViInt32 mode,ViInt32 value, ViInt32 autozero);
Parameters vi Instrument handle returned from agb1500_init( ).
adc A/D converter type. 0 (high-speed) or 1 (high-resolution).
mode Integration/averaging mode. 0 (auto), 1 (manual), or 2 (PLC).
value Coefficient for a reference value to set the integration time or
number of averaging samples. 1 to 1023.
The reference value depends on the adc and mode settings:
• For high-resolution ADC:
The reference value is the initial value for auto mode, 80 μs
for manual mode, or 1/power line frequency for PLC mode.
• For high-speed ADC:
The reference value is the initial value for auto mode, 1
sample for manual mode, or 128 samples for PLC mode.
where initial value is the value automatically defined by the
instrument, and you cannot change.
autozero ADC zero function. 0 (off) or 1 (on).
agb1500_setAdcType
This function selects the A/D converter type for the measurement channel.
Syntax ViStatus _VI_FUNC agb1500_setAdcType(ViSession vi, ViInt32 channel,
ViInt32 adc);
Parameters vi Instrument handle returned from agb1500_init( ).
channel Slot number of the slot that installs the SMU used to perform
measurement. See Table 2-2. Set 0 to select all SMUs.
adc A/D converter type. 0 (high-speed) or 1 (high-resolution).
