agb220xa_compenC
This function compensates capacitance/conductance data measured by the Agilent 4284A
LCR meter, and returns compensation results. Before this function is executed, a
compensation data file must be specified by using the
agb220xa_selectCompenFile
function. The file must contain the appropriate compensation coefficients for your
measurement environment. For obtaining the compensation coefficients for your
environment and creating the compensation data file, see
“To Create Compensation Data
File” on page 5-22.
Syntax agb220xa_compenC(ViSession vi, ViReal64 frequency, ViReal64 raw_c, ViReal64 raw_g,
ViPReal64
compen_c, ViPReal64 compen_g);
Parameters vi Instrument handle returned from agb220xa_init( ).
frequency Measurement frequency (in Hz). 1E3 (1 kHz) to 1E6 (1 MHz).
raw_c Capacitance (in F) measured by the 4284A.
raw_g Conductance (in S) measured by the 4284A.
compen_c Capacitance compensation result (in F). Returned value.
compen_g Conductance compensation result (in S). Returned value.
agb220xa_selectCompenFile
This function specifies the compensation data file used by the agb220xa_compenC
function. The file must contain the appropriate compensation coefficients for your
measurement environment.
For obtaining the compensation coefficients for your environment and creating the
compensation data file, see
“To Create Compensation Data File” on page 5-22.
Syntax ViStatus _VI_FUNC agb220xa_selectCompenFile(ViSession vi, ViString file_name);
Parameters vi Instrument handle returned from agb220xa_init( ).
file_name Compensation data file name. Use absolute path. If the value is NULL
string, the default data is used.
