DM-154
The
DM-154
demodulator is a high performance television tuner/demodulator which, in
addition to being at home in basic broadcast, cable and closed circuit monitoring
applications, can also be used for FCC compliance testing. It contains features beyond
standard tuners, including forced mono mode, a Zero Carrier Pulse (chopper), 4.5 MHz aural
carrier output, external IF loop and remote control via an RS-232 port. The DM-154 may be
used in testing applications and in locations where computer control is required.
DM-192
The
DM-192
is a 192 channel high performance agile demodulator that provides
features and performance found on demodulators over twice its price! It shares all of the
features of the DM-154 plus front panel selectable synchronous or envelope detection and
three types of full-time audio outputs plus composite audio out. Like all Videotek agile
demodulators, the DM-192’s front panel provides convenient control of all standard
operations. The DM-192 is ideal for high quality reception and testing applications and in
any application where all audio signals are required all the time.
