Operating instructions

PROMAX-8
The
The CHANNEL-FREQUENCY operating mode measures the video carrier
level, the Carrier/Noise ratio (C/N), the Video/Audio ratio (V/A) and activates
audio carrier demodulation for analogue channels; as well as measuring the
channel power and the Carrier/Noise ratio (C/N) for digital channels. It also
permits to measure the CSO and CTB intermodulation distortion.
The DATALOGGER operating mode enables multiple measurements to be
performed and memorised for subsequent checking, transfer to PC or
printing. It can perform and store up to 55 obtained measurements or loggers
in the memory. Each logger carries out level, C/N, V/A or channel power
measurements on the channels activated in the channel plan (up to a
maximum of 140 channels).
The SCAN operating mode shows the signal level of all channels present on
the chosen frequency band in a bar-graph display. The span and the
reference level may be selected through the rotary selector. In addition, a
moving marker shows the numeric level of any specific channel. This mode
also permits to define the pilot channels, used for the TILT measurement
(only in the forward band).
This key permits to accede to 2 operating modes:
The SPECTRUM ANALYSER mode provides a spectrum analysis over the
entire band in two parts: return path or sub-band (5 to 80 MHz) and forward
band (5 to 863 MHz). The span is user definable between 1 and 100 MHz. In
addition, it is possible to change the reference level, and maximum and
minimum levels may be detected and held for INGRESS measurements.
In the TRANSIENT DETECTOR mode, the
transitory counter in the return path. The level detection threshold and the
frequency margin are user definable.
