INSTRUCTION MANUEL. PROMAX-8+
CABLE TV ANALYSER

Description
The PROMAX-8+ is six instruments in one, Level Meter, Data Logger, Scan,
Tilt, Spectrum Analyser and Transient Detector, which makes it an excellent tool for
the installation and maintenance of analogue and digital television signal
reception/distribution systems working in the 5 to 862 MHz range, which includes FM
radio, community TV systems (MATV) and cable TV (CATV) including the reverse
band (sub-band).
As a Level Meter, the PROMAX-8+ enables the following measurements:
Analogue channels:
Digital channels DVB-C, DVB-T, and DAB:
The Data Logger function allows up to 55 loggers or measurements to be taken
and stored, each with carrier levels, and C/N and V/A ratios of up to 140 channels. The
measurements obtained may be checked, transferred to a PC or printed at any time.
In Scan operating mode, the PROMAX-8+ indicates the level of all channels
present on the band in a bar-graph display. The span and reference level are user
definable. A moving marker shows the exact level of each specific channel.
In Tilt operating mode, the screen shows, both graphically and numerically, the
difference in levels between any four previously defined pilot channels, in order to
obtain a qualitative measurement on band equalisation.
As a Spectrum Analyser it provides the analysis of the entire band, with a
span defined by the user from 1 to 100 MHz. Furthermore, it is possible to alter the
reference level, and to detect and maintain the maximum and minimum values for
INGRESS measurements.
