11.3 Intermodulation (IMD) Measurement
Figure 8. Intermodulation (IMD) Measurement
Intermodulation (IMD) frequencies are all frequency combinations coming from the two input carriers F1
and F2: F2–F1, 2
F1–F2, 2
F2–F1 and F1
+
F2, fall in the 40MHz–900MHz range.
F1 and F2 input levels are set to 90dBuV at the input of the BALUN. F1 and F2 frequency generator levels
(50W internal load) take into account a 50 to 75Ohm load difference (1
.
8dB), plus losses in the 3dB
coupler and the 50 to 75Ohm transformer.
Intermodulation measurement is the difference (in dBc) between the F1 or F2 level at the Output (VCRTU
or TVOUT) and the frequency combinations level, for the following cases:
Intermodulation specification is the IMD measurement’s worst case.
F1=50MHz and F2=60MHz
F1=300MHz and F2=310MHz
F1=600MHz and F2=610MHz
F1=100MHz and F2=110MHz
F1=400MHz and F2=410MHz
F1=700MHz and F2=710MHz
F1=200MHz and F2=210MHz
F1=500MHz and F2=510MHz
F1=800MHz and F2=810MHz
