4.2 Operating instructions
The PROPOWER-5 has 6 independent operating modes:
The CHANNEL-FREQUENCY operating mode measures the signal level for
a tuned frequency as well as the channel power and the Carrier/Noise ratio
( C/N ) for digital PLC channels. Press this key to change between channel
tuning mode and frequency tuning mode.
The DATALOGGER operating mode enables multiple measurements to be
performed and memorised for subsequent checking, transfer to PC or
printing. It can perform and store up to 55 obtained measurements or loggers
in the memory. Each logger carries out, C/N and channel power
measurements on the channels activated in the channel plan (up to a
maximum of 140 channels).
The SCAN operating mode shows the signal level of all channels present on
the chosen frequency band in a bar-graph display. The span and the
reference level may be selected through the rotary selector. In addition, a
moving marker shows the numeric level of any specific channel. This mode
also permits to define the pilot channels, used for the TILT measurement.
This key permits to accede to 2 operating modes:
The
SPECTRUM ANALYSER mode provides a spectrum analysis over the
entire band. The span is user definable between 1 and 50 MHz. In addition, it
is possible to change the reference level, and
maximum and minimum
levels may be detected and held for INGRESS measurements.
In the TRANSIENT DETECTOR mode, the PROPOWER-5 operates as a
transitory counter in the return path. The level detection threshold and the
frequency margin are user definable.
The TILT operating mode shows on the display, both graphically and
numerically, the level difference between any four channels, previously
defined as pilot channels, in order to obtain information about band
equalisation.
