Chapter 1: General Information
The
S7200
is a handheld TV Signal Analyzer that integrates multiple measurement applications in a single
instrument, ideal for use by CATV field technicians and HE engineers. These applications provide most of the
measurements required to maintain optimum performance of a CATV network.
The firmware installed on the S7200 is updated on a regular basis. This User Guide documents procedures for
operating the instrument based on the most recent firmware version up to the date listed on the guide.
1-1 About the S7200 TV Signal Spectrum Analyzer
The product of revolutionary advances in TV signal analysis technology, the S7200 includes a host of
features typically found in more expensive instruments and provides outstanding performance for value.
The S7200 enables field engineers to perform in-service measurements and identify interference signals that
are invisible to many field instruments currently available on the RF test equipment market. The high-speed
spectrum analysis tool supports multiple cable, terrestrial, and satellite digital TV standards, including DVB-
C/C2, DVB-S/S2, DVB-T/T2, DTMB, DAB, and ATSC or ISDB-Tb (on select models – see below). It can measure
frequencies of 4 ~ 1220 MHz for cable/terrestrial testing, and 950 ~ 2150 MHz for satellite applications.
The TV analyzer function also supports a wide range of video encoding formats, like MPEG2/4, H.264, H.265,
AVS(+), and VC-1, with HD and SD image decoding (4K, 1080p, 720p, 576i, etc.) With the optional DVB-CI
tool, users can even decode encrypted programs. The S7200 also supports mode 1/E BISS decryption.
Support for analog TV standards includes NTSC, PAL, and SECAM.
As 700 MHz becomes more popular for LTE service, LTE signals effectively occupy the same frequency band
as CATV service. The S7200’s time-domain EVS function allows users to check LTE interference without
interrupting service.
The S7200 can perform TS (transport stream) analysis with the RF and ASI ports; simply record the output to a
SATA SSD or USB device for easy playback. In line with recent strides in optical LNB use, optical power meter
and optical receiver options are available. Other optional features include IPTV, WiFi analysis, and a GPS
dongle for key location measurements.
Each instrument comes with basic TV and spectrum measurement functions for particular standards, based
on the model. Optional functions may be enabled either at the time of purchase, or at a later date as your
test needs evolve. See the following model and option guides.
