TELECOMMUNICATIONS TEST EQUIPMENT - Promax

PROLINK-7
TV & SATELLITE ANALYSER
The PROLINK-7 is a revolutionary signal analyser, designed for the installation and maintenance of television and data systems.
Its functions have been designed to achieve optimum performance in the reception and distribution of terrestrial, cable TV and satellite TV, microwave networks
(MMDS)and radio signals.
It enables the user to analyse the quality of both analogue and digital TV transmissions. The features also meet the strict technical requirements needed to install
VSAT (Very Small Aperture Terminals) systems.
Its frequency range covers from 5 MHz up to 2150 MHz. Therefore, it is suitable for taking measurements in the return path in cable TV applications as well as
in the satellite IF band.
All functions can be accessed by a single selector located on the front panel and associated menus which allow for a quick and intuitive instrument operation.
Types of measurements Analogue-Digital
It accepts any analogue TV standard and any TV
system. Signal measurements can be made within
the satellite IF band, with positive or negative video
modulation. It allows the following measurements:
Level, Video to Audio ratio and Carrier to Noise
ratio. The display of the sync pulse signal and the
teletext are extremely useful to achieve optimum
performance for analogue TV signals.
For digital signals it provides the channel Power and
also the Bit Error Ratio (BER), the last by means of
the appropriate option.
The graphic bar representation and the acoustic
level tone are ideal for the maximum signal adjustment.
It also provides an audio demodulator.
Spectrum mode. Variable resolution.
The equipment includes a spectrum analysis
function, which permits to identify any signal in
real time with the maximum easy. It has different
resolution filters: 1 MHz (only terrestrial bands)
4 MHz (only satellite band), 230 kHz and 100
kHz, which can be selected for an optimum use
in any type of application. In this way, for example,
the 4 MHz filter will be the most suitable for
satellite dish alignment and for optimum
adjustment of the cross polarisation. With this
filter one can perfectly distinguish a digital
channel from an analogue one. In the other
applications such us VSAT selecting a narrow
filter will be more useful.
Memories and Data Acquisition
The instrument can store up to 99 different configurations,
with settings of frequency or channel,
the name of the broadcasting station, measurement
units, measurement type, etc.
By using the Data Logger, the equipment is converted
into a powerful data adquisition systemwith
a memory of 9801 parameters. This permits
the user to carry out up to 99 measuring sessions
on a maximum of 99 channels. Measurements
can be done automatically and in predetermined
time periods. All functions can be remote controlled
by use of RM-007.
