NI PXI-5600 Calibration Procedure 30 ni.com
niTuner_CalGetStepFrequency
Function Prototype
long niTuner_CalGetStepFrequency
(
unsigned int calHandle,
double startFrequency,
double stopFrequency,
unsigned int numberOfSteps,
unsigned int index,
double* stepFrequency
)
Purpose
This function starts a procedural loop and returns the frequency of the current loop iteration.
Use this function to adjust the temperature coefficient, IF frequency response, and RF
frequency response. Set the proper values for the inputs startFrequency, stopFrequency,
and numberOfSteps as specified in the calibration procedure.
Parameters
Name Description
calHandle The calibration session reference
startFrequency The start frequency (in Hz) of the loop
stopFrequency The stop frequency (in Hz) of the loop
numberOfSteps The number of frequency steps in the loop, including the start and
stop frequencies
index The current value of the loop; an index of 0 refers to the first
iteration of the loop
frequency The frequency of the current loop iteration
