LS-68-M can offer up to two fully AGC /
baseline controlled PCM bit synchronizer
channels with software selectable input
impedance.
To get a sense for the massive scope of
the size/weight/power reduction achieved
by the Lumistar design team, it is
interesting to note the previous
generation Lumistar products would
operate with a 300 watt power
requirement, weight of 62 pounds and
were housed in a 4U Windows computer
chassis occupying approx. 3100 cubic
inches. Lumistar’s latest 4th generation
product consumes 40 watts typically,
weighs 2 pounds, and occupies a volume of
25 cubic inches. This equates to using 13%
of the power, 3.2% of the weight and
occupies less than 1% of the volume of its
predecessor.
One of the primary design goals was to
get the traditional telemetry processing
and simulation functionality product “off
Windows” and provide it as a “network
appliance”, which was achieved. The unit is
controlled and monitored using only Gigabit
Ethernet and/or USB and/or RS-232
protocols. Using our Interface description
documentation, the customer can create
their own interface GUI or use Lumistar’s
standard applications.
At the heart of the modular design is a
flexible and extensible DSP Engine that
can take on multiple personalities. The
