Midian VS-1000, Manual

GENERAL INFORMATION
VS-1200:
The VS-1200 is a Digital Signal Processor (DSP) based Frequency Domain voice scrambler offering a high level
of voice privacy. The DSP converts the analog signal into quantitized digital data. It then converts the “Time
Domain” signal into the “Frequency Domain”. This results in an audio “frequency spectrum”, which is then
partitioned into bins that are encrypted by the non-linear key generator. The digitized data is converted back to
the analog realm using a digital to analog converter.
The above technique and the lack of synchronization result in excellent audio quality, high security and enable the
VS-1XXX to be used in virtually any type of radio system. These systems include HF SSB, Conventional Two-
Way, Trunking, Voting and Simulcast.
In addition to the scrambling functions the VS-1200 offers ANI and Emergency ANI encode in the following
formats:
•
Motorola’s MDC-1200
•
Kenwood’s FleetSync
•
M/A-Com’s G-Star (aka GE-Star)
•
DTMF
•
5-Tone (all formats)
VS-1000:
Midian’s VS-1000 voice inversion scrambler provides an entry level of voice security for two-way radio
communications. The VS-1000 provides up to 16 different inversion frequencies that are selectable using 4-line
binary. These inversion frequencies are programmable using Midian’s KL-3. The VS-1000 is compatible with
Midian’s VPU series voice inversion scramblers.
VS-1050:
Midian’s VS-1050 is a voice inversion scrambler with multi-format ANI encode. The VS-1050 has the same
scrambling features as the VS-1000, but adds ANI and Emergency ANI encode in the following formats:
•
Motorola’s MDC-1200
•
Kenwood’s FleetSync
•
M/A-Com’s G-Star (aka GE-Star)
•
DTMF
•
5-Tone (all formats)
