The Frequency Scan function shows the level of all active channels in the
channel plan through a bar chart.
By the Generator Function, it is possible to create a test signal that allows you to
equalize properly the transmission band (upstream).
As Spectrum Analyser function provides an analysis of the whole band, allowing
change the reference level and the span among others.
As Analyser Data Systems for DOCSIS / EuroDOCSIS, the PROMAX-27 allows
you to measure downstream, upstream and the constellation.
The VoIP function performs a network analysis based on quality service
parameters established by the operation mode UGS (Unsolicited Grant Service) for data
packets transmission, which is based on DOCSIS / EuroDOCSIS standard. Therefore,
those will ensure the best call quality.
PROMAX-27, as IPTV services analyser, performs a comprehensive analysis of
the network based on the quality of service (QoS) named rtPS (real time Polling
Service), which is one of the quality services defined by DOCSIS / EuroDOCSIS
standard. That will ensure the best quality of TV over cable.
The PING function performs an analysis of standard Internet traffic, such as
browsing websites, emails or instant messaging. To check the quality of service, it uses
the quality of service defined as BE (Best Effort) based on the standard DOCSIS /
EuroDOCSIS.
In short, implementation of all these functions into an light instrument of one kilo
and a half weight, ergonomic design and robust, makes PROMAX-27 into an
unparalleled tool at fieldwork.
