R&S®ETH Handheld TV AnalyzerAt a glanceEasy-to-replace battery.The
R&S®ETH handheld TV analyzer is the compact combination of a
TV analyzer, spectrum analyzer and network analyzer. It supports the
digital DVB-T, DVB-H and ISDB-T TV standards. Its functional
展开剩余82%versatility eliminates the need for other measuring equipment.
The analyzer covers the frequency range up to 3.6 GHz or 8 GHz.
The housing was specially designed for portable use and is therefore
rugged and splash-proof. The large, daylight-friendly color display,
he low weight and the replaceable lithium-ion battery enhance the
analyzer's portability. To improve its receive sensitivity and selectivity,
the R&S®ETH can be equipped with internal preselection followed by a
preamplifier. The core component of the R&S®ETH is an FPGA-based realtime
digital TV demodulator that offers maximum measurement performance and
provides a demodulated MPEG-2 transport stream at the TS-ASI output. The
measurement results are displayed on straightforward measurement screens
and can be stored in the internal memory or on external storage media such
s SD card or USB memory stick. The R&S®ETHView Windows PC software,
which comes with the analyzer, allows easy documentation of measurement
results. R&S®ETHView enables the user to edit and redefine the channel tables,
measurement profiles, transducers and limit tables delivered with the instrument
and to load them in the R&S®ETH. The data is transferred via the USB or
LAN interface.Key facts❙ TV, spectrum and network analyzer in a single box ❙
