Modulation type 16/32/64/128/256 QAM ITU J1 annex A/C and
64/256 QAM ITU J1 annex B.
Bandwidth 8 MHz.
Frequency tuner 62.5 kHz.
VIDEO / AUDIO RATIO MEASUREMENT (ANALOGUE CHANNELS)
Measurement Ratio of video to audio carrier levels.
Measurement range From 0 to 40 dB.
Audio subcarrier frequency
Variable
4-9 MHz.
Accuracy ± 3 dB (from 5 to 40

CARRIER / NOISE RATIO MEASUREMENT
Measurement
Analogue channels Ratio between carrier level and the channel's noise
level.
Digital channels Ratio between the channel power and the noise
level. The frequency where noise is measured is
user definable in absolute or relative value. In the
relative mode, the unit takes as default frequency
offset the value BW/2 + 0.5 MHz.
Measurement range
Analogue channels 40-50 dB for input level between 60 and 70 dBµV.
> 50 dB for input level > 70 dB

CSO & CTB INTERMODULATION PRODUCTS MEASUREMENT
(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 frequencies User definable from -2.50 to 2.50 MHz. (Default
values -1.50, -0.50, 0.50 and 1.50 MHz).
CTB Ratio of the peak level of the video carrier to the
peak of the distortion products of third order beat.
Measured at the carrier frequency or, approximately
mode, in a channel previously defined by the user.
DATALOGGER FUNCTION
Max. number of loggers 55.
Number of channels/logger 140.
Measurements
Analogue channels Level, C/N and V/A.
Digital channels Channel power and MER. (BER for data dumping to
printer or transfer to PC).
