ViStatus IviSpecAn_ConfigureFrequencyOffset (ViSession vi, ViReal64 frequencyOffset);
Purpose
This function configures the frequency offset of the spectrum analyzer. This affects the setting of the spectrum analyzer's absolute frequencies, such as start, stop, center, and marker. This function does not modify the settings for differences of frequencies, such as span and delta marker.
