PCL SPECTRUM ANALYSER
PROPOWER-5
1 GENERAL
1.1 Description
The PROPOWER-5 is six functions in one instrument, Level Meter , Datalogger ,
Scan , Tilt , Spectrum Analyser and Transient Detector which makes it an excellent
tool for the installation and maintenance of Power Line Communications (PLC)
systems working in the 1 to 50 MHz range.
As a Level Meter , the PROPOWER-5 enables the following measurements:
Digital PLC channels :
Channel power measurement by integration
Carrier / Noise ratio measurement (C/N)
Level measurement in a frequency
The Datalogger function allows up to 55 loggers or measurements to be taken
and stored, each with C/N ratios and channel power 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 PROPOWER-5 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 50 MHz. Furthermore, it is possible to alter the reference
level, and to detect and maintain the
maximum and minimum values for INGRESS
measurements.
The
Transient Detector mode, permits to count the number of impulsive
interferences and with a level higher than a threshold defined by the user. The
maximum frequency range is from 1 to 50 MHz.
In designing the PROPOWER-5 , special attention was given to building a
multi-purpose, accurate, yet easy-to-use instrument. A simple keyboard gives direct
access to the various operating modes and, once in them, any measurement parameter
can be easily changed using the rotary selector/button.
In addition, it has an RS-232C terminal for connecting to a printer or computer for
producing reports on the measurements obtained.
