Description
The PROMAX-26 is seven functions in one instrument, Level Meter,
Datalogger, Scan, Test Generator, Spectrum Analyser, Cable TV and DOCSIS /
EuroDOCSIS Data Systems Analyser which makes it an excellent tool for the

and
maintenance
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), and also to test DOCSIS and
EuroDOCSIS data transmision systems.
The PROMAX-26 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-26 enables the following measurements:
Analogue channels:
-
-
-
Digital channels:
-
-
-
The Datalogger function allows up to 100 loggers or measurements to be taken
and stored, each with carrier levels, C/N and V/A ratios, channel power, BER and MER
of up to 140 channels in cable TV analyser mode as web as the measurements
obtained working as data system analyser . The measurements obtained may be
checked, transferred to a PC or printed at any time.
In Scan operating mode, the PROMAX-26 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.
