  • Added gain and phase compensation option in Spectrum Analyzer Processing for transfer function measurement. This option can be used to compensate the gain and phase difference between the two input channels of the measuring device itself. The "Spectrum Analyzer Generate Frequency Compensation File (Flat)" option in the context menu of Spectrum Analyzer is enabled accordingly for Transfer Function mode.
  • Added "Convert to Impedance" and the related parameters in Spectrum Analyzer Y Scale to convert Amplitude Spectrum display to Impedance vs Frequency display using the single-channel method.
