Note:
The measurement of higher-order intermodulation products must be enabled
explicitly in the "Define Intermodulation" dialog, see
Chapter 5.5.4.3, "Define Intermo-
dulation Distortion Measurement Dialog"
●
The "Lower IM3 Product at DUT Out" is the third-order lower intermodulation prod-
uct at the output of the DUT. This quantity corresponds to the outgoing wave quan-
tity (b wave) at the output of the DUT, measured at the frequency of the lower tone
minus the tone distance.
The lower and upper IM<n> frequencies are also displayed in the "Frequencies
and Powers" dialog, see
Chapter 5.5.4.4, "Frequencies and Power Dialog"
●
The "Upper IM3 Product at DUT Out" is the third-order upper intermodulation prod-
uct at the output of the DUT. This quantity corresponds to the outgoing wave quan-
tity (b wave) at the output of the DUT, measured at the frequency of the upper tone
plus the tone distance.
●
The "Major IM3 Product at DUT Out" is the lower or upper IM3 product at DUT out,
whichever is larger. The "Major IM3 Product" reveals the worst-case performance
of the DUT.
●
"Major IP3 at DUT Out" is the third-order major intercept point at the output of the
DUT. This quantity corresponds to the fictitious DUT output level (Lower Tone at
DUT Out), measured at the lower tone frequency, where the major third-order inter-
modulation suppression (the ratio of the Major IM3 Product at DUT Out to the
Lower Tone at DUT Out) reaches 0 dB.
●
"Lower Tone at DUT In", "Lower Tone at DUT Out", "Upper Tone at DUT In",
"Upper Tone at DUT Out" is a measurement of the two fundamental waves that are
used for the intermodulation measurement.
●
"Noise at DUT Out" is a measure for the noise level and therefore the dynamic
range of the intermodulation distortion measurement. The noise level is measured
at the frequency of the lower tone minus half the tone distance.
