CABLE TV ANALYSER

Description
The PROMAX-10 is seven functions in one instrument, Level Meter ,
Datalogger , Scan , Tilt , Spectrum Analyser , Transient Detector , and Cable Digital
Analyser 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), cable TV
(CATV) and wireless cable TV (MMDS) including the sub-band (return path).
As a Level Meter , the PROMAX-10 enables the following measurements:
Analogue channels :
Digital channels DVB-C, DVB-T, and DAB :
The Datalogger function allows up to 55 loggers or measurements to be taken
and stored, each with carrier levels, C/N and V/A ratios, channel power or MER 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-10 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 frequency 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.
