agb1500_execOpenCorr
This function performs the CMU open correction for the specified measurement
frequency, and sets the correction data to the B1500. This function also returns the
execution results. This function initializes the MFCMU.
To execute this function, open the measurement terminals at the end of the device
side, or connect the open standard that has the reference value or calibration value.
If the standard is used, enter the values to the primary and secondary parameters to
set the reference value to the B1500. If you do not use the standard, set
primary=secondary=0.
The agb1500_forceCmuAcLevel function must be executed before this function.
Syntax ViStatus _VI_FUNC agb1500_execOpenCorr(ViSession vi, ViInt32 channel,
ViReal64 freq, ViInt32 mode, ViReal64 primary, ViReal64 secondary,
ViPInt16 result);
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.
freq Frequency (in Hz). 1000 (1 kHz, initial setting) to 5000000
(5 MHz). Setting resolution: 1 mHz (1 kHz to), 10 mHz
(10 kHz to), 0.1 Hz (100 kHz to), or 1 Hz (1 MHz to 5 MHz).
mode MFCMU measurement parameters. This value must be 100 at
this time.
primary Reference value of the standard. This must be the parallel
capacitance value. Numeric expression.
secondary Reference value of the standard. This must be the conductance
value. Numeric expression.
result Execution result of this function. Returned value.
0: Passed. No failure detected.
