© National Instruments Corporation 27 NI PXI-5600 Calibration Procedure
niTuner_CalGetCurrentTemperature
Function Prototype
long niTuner_CalGetCurrentTemperature
(
unsigned int calHandle,
double* temperature,
double* correctionFactor
double* temperatureCoefficient
)
Purpose
This function returns the temperature of the NI PXI-5600 downconverter in °C, the correction
factor in dB, and the temperature coefficient in dB/°C. Retrieving the downconverter
temperature causes a momentary disruption in the IF output signal, which may cause invalid
IF data.
Parameters
Name Description
calHandle The calibration session reference
temperature The current temperature of the NI PXI-5600 in °C
correctionFactor The correction factor in dB based on the current temperature
(normalized to 40 °C and multiplied by the calibrated temperature
coefficient dB/°C)
temperatureCoefficient The temperature coefficient in dB/°C used to calculate the
correctionFactor based upon the current temperature
