Rohde & Schwarz Showcases Portable TV analyzer
by | Sep 12, 2008 - 12:52:02 PM
The new R&S ETH portable
TV analyzer from Rohde & Schwarz offers the functionality of a TV analyzer,
spectrum analyzer and network analyzer in a single box. Compact and
lightweight, the R&S ETH can easily be transported over long distances,
which makes it ideal for tasks such as installing and servicing low-power
transmitters in remote locations. Moreover, the instrument provides a quick way
for network operators to perform coverage measurements in the field, at public
sites or in buildings. The R&S ETH supports the DVB-T and DVB-H standards.
It is available in four models with a frequency range of 100 kHz to 3.6 GHz or
up to 8 GHz, either with or without a tracking generator.
The latest realtime TV analyzer from Rohde & Schwarz offers high-end
quality at an affordable price. Since the analyzer provides an MER value
greater than 40 dB, measurements of signal quality can be performed directly on
the transmitter. The integrated spectrum and network analyzer transform the
R&S ETH into a single instrument that performs all measurements. This makes
daily checks of transmitters at different locations an easy task. Moreover, the
analyzer's high-contrast color display and its ability to run up to 4.5 hours
on battery power make it ideal for outdoor use.
The TV analyzer features a built-in preselector and a preamplifier. This raises
dynamic range and sensitivity so that even weak signals can be detected via
antenna. Customers can use either their own antenna or one from Rohde &
Schwarz.
The demodulator developed by Rohde & Schwarz for DVB-T/-H is based on FPGA
technology. Since the FPGA is the key component, changes in the standard can
easily be integrated via software – as can additional TV standards. This makes
the R&S ETH a particularly safe investment because no additional hardware
is required to maintain state-of-the-art functionality. The instrument's use of
identical signal paths for demodulation and signal analysis ensures consistent
measurement results.
The R&S ETH handheld TV analyzer is the perfect tool for service
technicians in the field, for regular functional checks of gap-filler
transmitters and for measuring transmitter coverage in DVB-T/-H networks. The
analyzer will be available from Rohde & Schwarz in December 2008.
