1. Response and return loss characteristics are tested and guaranteed for the full 5.0 - 200 MHz frequency range.
2. Freescale 100% distortion and noise figure testing is performed over the 5.0 - 175 MHz frequency range. Cross modulation and composite
triple beat testing are with 22 - channel loading; Video carriers used are:
T7 - T13
7.0 - 43.0 MHz

2 - 6 55.25 - 83.25 MHz 5 - Channels
A-7
121.25 - 175.25 MHz 10 - Channels
3. Video carriers used for 12- Channel typical performances are T7 - 6; For 26- Channel typical performance, Channels 8, 9, 10 and 11 are added
to the 22 - Channel carriers listed above.
