The R&S®EFL240 and R&S®EFL340 are
compact, portable TV test receivers for cable, satellite and terrestrial
television. Installation personnel and service technicians, for example, can
use them to check the signal quality of cable TV systems and in-building
distribution systems. The ergonomic design makes the receivers easy to operate,
which in turn makes the technicians who use them more productive. The battery
operating time of over four hours is significantly longer (up to two hours
more) than that of competitive TV test equipment on the market.
The new test receivers feature a wide variety of measurement
functions for digital and analog TV standards and FM sound broadcasting. The
R&S®EFL340 supports DVB-T2, the latest digital TV generation. Both
instruments measure all essential test parameters and display the constellation
diagram and the modulation error ratio (MER) versus frequency. A feature that
is certain to be popular with technicians is the ability to measure echoes even
outside the guard interval for analyzing reception problems in multipath
propagation and single-frequency networks.
The two receivers can perform spectrum analysis in a frequency
range up to 2500 MHz. The practical built-in zoom function allows service
technicians to zoom in on a channel and measure it in detail while maintaining
an overview of the entire TV cable spectrum.
Video and audio content are the simplest and most direct criteria
for checking reception quality. To facilitate this test, both instruments are
capable of decoding MPEG-2 and displaying SD and HD programs. The
R&S®EFL340 also supports MPEG-4. The Common Interface integrated in both
receivers even makes it possible to display encrypted services. The Combo mode
is a unique feature for simultaneously displaying measurement results, spectrum
and video. The user can see all important information at a glance.
In addition, the two TV test receivers have several functions that
facilitate routine jobs: The Scan & Log function and the Macro Measurement
function efficiently automate frequent measurement tasks. Pre-installed channel
tables and transponder lists save the user valuable time when entering parameters.
