CABLE TV ANALYSER
PROMAX-10
Premium
1 GENERAL
1.1
Description
The PROMAX-10
Premium
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).
The PROMAX-10
Premium
incorporates the power level measurement function
in the whole frequency band, very useful to check a possible input saturation of some
broadband demodulators.
As a Level Meter, the PROMAX-10
Premium
enables the following
measurements:
Analogue channels:
-
Video carrier level measurement
-
Carrier / Noise ratio measurement (C/N)
-
Video / Audio ratio measurement (V/A)
-
CSO and CTB Intermodulation distortion measurement
Digital channels DVB-C, DVB-T and DAB:
-
Channel power measurement by integration
-
Carrier / Noise ratio measurement (C/N)
-
Bit Error Rate (BER) measurement
-
Modulation Error Ratio (MER) measurement
-

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
Premium
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.
