LF990 Signal Level Meter – Multi-Function For The Digital Age
www.LeaderAmerica.com
Designed specifically for the ISDB-Tb terrestrial format now
being implemented in South/Central America.
Accepts 5MHz – 870MHz/ 950MHz – 2,600MHz
(F-type connector; 75
Ω)
Supports both digital and analog transmission systems to aid
in the analog to digital transition.
Supports QPSK, 16-256QAM and OFDM for CATV operation.
Supports broadcast, cable operation.
Measures RF Level, C/N. BER, MER and DELAY PROFILE.
Provides Constellation display and Spectral Display.
Presets and measurement logs can be stored in USB thumb-
drive for ease of use and documentation purposes.
Provides auto-channel search function for terrestrial and CATV.
Color LCD (TFT) display provides easy to read and understand
displays.
Remote control via USB interface.
Lithium-Ion battery operation, battery and AC adaptor included.
Equipped with the latest innovations in RF Signal level measurement,
the new LF990 brings flexibility, reliability and accuracy to your every
day measurement challenges. The instrument handles both analog and
digital terrestrial broadcast, as well as CATV RF signals. Level, C/N
(carrier to noise), BER, MER and delay measurements can easily be
performed when evaluating digital transmission paths. Level, MER and
BER measurements are provided simultaneously. The instrument also
offers a spectral display with 7MHz, 21MHz and 49MHz spans and
displays the spectrum of up to a span of 7 contiguous digital channels.
The LF990 provides compatibility with a number of analog and digital
modulation formats including OFDM, QAM and others and, in addition
to Level, C/N, MER and BER measurements, it produces constellation
and spectral displays.
Up to 200 presets can be stored and recalled and a measurement log is
provided. Measurements can be output as comma separated values
and used in a spreadsheet making record keeping easy to obtain and
communicate to others.
A bright color LCD (TFT) display provides information and readouts in
an easy to use and understand manner. The instrument is powered by
a Lithium-Ion battery for extended operation. Battery and AC adaptor
are included.
