In an effort to replicate and
enhance the current CSS500 “Video-on
Demand” test system, National
Analytics proposed a
state-of-the-art interactive data
acquisition system designed to
actively characterizes the integrity
of RF modulators over a frequency
range of 5 to 806 MHz in the NTSC
and PAL formats.Measurements include Visual
Carrier Level, (dBmV), Visual
Carrier Frequency, (MHz), Aural
Carrier Level, (dBc), Aural
Frequency Offset, (MHz), Modulation
Depth, (%) and Aural Deviation,
(kHz).
The system is fully configurable to
allow the operator to assemble a
channel line up to be characterized
over a variety of measurements.Resulting data reports are
exportable in ASCII text, jpeg, or
Excel formats.The system, (MATV/CATV), is
to be used to characterize the
“Video-on Demand” systems currently
being used by most major hotel
chains.
