IT-087 Digital TV QAM
Signal Analyzer
The IT-087 Digital TV Signal Analyzer is a configuration of the IT-08 Multifunction TV Meter
comprised of MB-08 Base Unit and MC-087 Removable Module. IT-087 is designed to ensure
high-performance installation and maintenance of reception and distribution systems for
DVB-C and analog television signals. IT-087 is capable to satisfy all your measurement
requirements for high-quality operation of any device within the range of 45 to 865 MHz,
what is due to the engaged basic functions for signal analysis, and in turn ensures accurate,
economical and easy use of Digital TV Signal Analyzer
IT-087 GENERAL FEATURES:
lightweight and compact handheld design
offered measurement modes:
CONSTELLATION DIAGRAM ANALYSIS mode with x1/x4 zoom factor
BER/MER MEASUREMENT mode, indicates results on a bar-graph display
DVB-C CHANNEL QUALITY MEASUREMENT mode, indicates results on a text display
LEVEL mode performs measurements of analog and digital channel parameters;
SPECTRUM mode provides spectrum analysis within a span defined by the user from
14 to 112 MHz;
SCAN, TILT and RIPPLE modes indicate the level of all the channels (or channels
according to the channel table), present in the band, on a bar-graph display and
provide the tuning of channel levels
level measurements:
for analog channels: image carrier level, Carrier to Noise (C/N) ratio, Video to Audio
(V/A) ratio;
for digital channels: channel power, Carrier to Noise (C/N) ratio
DVB-C measurement:
modulation error rate (MER)
bit error rate (BER) before RS decoder
real error counter, total
digital signal quality test (PASS/FAIL, MARGIN)
central frequency offset
data logger function enabling storage of:
up to 32 channel plans (up to 112 channels per each table) with possibility of table
auto creation. Auto scanning for lock parameters of DVB-C channels
up to 112 logs of measurements each indicating carrier levels, C/N and V/A ratios, all
the parameters checked against the required template and saved with comments and
measurement date and time. Bandwidth power, S/N rate, BER, MER are measured for
DVB-C channels
up to 110 spectrum analyzer logs (with band width less than 100 MHz) or up to 14
pages (with full frequency band) with 125kHz step within the selected band, the
parameters are saved with comments and measurement date and time
checking of audio with the internal loudspeaker
measurement of AC/DC input voltage from 10 to 100 V range
PC compatible (extra service modes, download data logger pages, printing of reports and etc.)
firmware update by the user
equipped with RS-232 interface
