Analogue and digital

PROMAX-10 Premium is a multi purpose CATV Analyser ideal for all size MSO's and contrac-tors as a service and installation tool. The most outstanding feature of this unique meter is its
capability to measure MER and BER on QAM digital channels but it is not missing any of the
measurements a meter of its class must have. Also it allows to check a possible input saturation
of some broadband demodulators by means of the power detection function.As a signal level meter it can be tuned by frequency or by channel. Various channel tables areavailable on board and they are all customer definable. Operating as much by means of the
channel tuning as of frequency tuning mode can offer several advantages such as:- Detection of the total power. This parameter indicates the total power that is being transmittedthrough the connected coaxial cable to the PROMAX-10 Premium in the band from 5 to 862 MHz.- Automatic selection of analog or digital measurement mode.
- Faster tuning via rotating tuning knob.
- No need to type-in channel number or frequencies.
- Combined multi-measure display (video, video/audio, carrier/noise). >

Multifuntional Display

The PROMAX-10 Premium displays with each ofthe measurements all the information required for
the evaluation of the quality of signal under test. It
has a GRAPHIC BAR for the interpretation,
adjustment and convenient optimization of any
cable television system , microwave link or terres-
trial aerial. >

Scan

In this mode we can see all the channels ofthe selected channel plan graphically repre-
sented with their associated signal levels. A
MARKER can be placed on any of the chan-
nels displayed on the screen in order to find
their frequency or their signal level.The SPAN and the REFERENCE LEVEL can
be changed in order to adapt the presentationto the users test require ments. >

Digital channel power

It is also possible to tune the audio carrier,
allowing demodulation to listen to the sound
via a built-in loudspeaker.

Just pressing a button, the channel power
measurement (using an integration method),
carrier/noise, BER and MER can be carried
out. It has been demonstrated that measure-ments as MER, are useful to determine the
digital signal quality, reason why is essential
to have them available in the measurement
instruments. >

Carrier to Noise (C/N)

To evaluate the signal quality, the
Carrier/Noise Ratio with a sensitivity level of
2 dB is also fundamental as parameter to eva-luate the signal quality, both in analogue and
digital transmission. In the menu this C/N ratio
is displayed together with Signal Level or
Channel Power, Audio Level and Video /
Audio Ratio. >
