Digital channels: >40 dB for input level >60 dBmV ±2 dB (45-862 MHz) ± 3 dB (5-45 MHz)
CSO-CTB Intermodulation (Analogue channels)
CSO: Ratio of the peak level of the video carrier to the peak of the distortion products of second order beat.
Measured at four frequencies user definable.
Measuring frequency : From -2.50 to - 0.50 MHz and from 0.50 to 2-50 MHz
(Default values-1.5, -0.5 + 0.5 y + 1.5 MHz). CTO: Ratio of the peak level of the video carrier to the peak of the distortion products of third order beat.
Measured at the earner frequency or, approximately mode, in a channel previously defined by the user.
