File Format for Mixer Delay Calibration Files
The analyzer uses a simple ASCII format to export mixer delay correction data. By default, the mixer delay
calibration file has the extension *.mcal and is stored in the directory shown in the Save Correction Data
and Load Correction Data dialogs. The file starts with a preamble, followed by a list of stimulus values
(frequencies or power levels) and group delays.
Reset Freq Conv and Mix Dly
This softkey disables the mixer delay measurement mode and switches back to normal (non frequency-
converting) mode.
A Mix label in the channel list indicates that a frequency-converting mode is active. A MixDly label in the
trace list indicates an active mixer delay measurement.

Harmonics
The Harmonics submenu controls the measurement of arbitrary harmonics or ratios between harmonics
and the fundamental wave. Together with the Mixer measurement and the arbitrary configuration of
generator and receiver frequencies (Port Configuration), the harmonics measurement is included in option
R&S ZVA-K4.
Harmonics Measurements
Harmonics are signals at an integer multiple of the fundamental frequency. The fundamental is the first
harmonic, the nth harmonic is n times the frequency of the fundamental. The production of harmonic
frequencies by an electronic system when a signal is applied at the input is known as harmonic distortion.
The purpose of the Harmonics menu is to measure the harmonic distortion of a DUT. To this end the
source remains at the fundamental frequency whereas the receiver is set to n times the fundamental
frequency. Two different types of results are provided:
 In the direct measurement, the nth harmonic of the stimulus signal is measured. The result is
displayed as a wave quantity but can be modified and converted using the functions in the Trace
menu.
