Selecting the Difference Frequency Distortion and Measurement Standards
Use
You can select the display mode for the difference frequency distortion
according to the measurement standards:
d2 (IEC 268)
Measurement and display of the 2nd order intermodulation product
acc. to IEC 268
d3 (IEC 268)
Measurement and display of the 3rd order intermodulation product
acc. to IEC 268
d2 (IEC 118)
Measurement and display of the 2nd order intermodulation product
acc. to IEC 118
d3 (IEC118)
Measurement and display of the 3rd order intermodulation product
acc. to IEC 118
Note:
The intermodulation distortion (IMD) tones are not subjected to a level
testing case of measurement according to IEC 118. This means that a DFD
measurement is possible even if the IMD signal is severely distorted (e.g. as
a result of the frequency response of the DUT or of the transmission path). A
typical example is the measurement of earpieces.
Note:
The setting is always valid for both channels (Ch 1&2).
