Page 4: General Information
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. -
Page 5: Product Programming
PRODUCT PROGRAMMING Note: Greater details of the VS series products can be found in the VS Series Technical Reference Manual. Midian’s VS-1xxx-KW2 is programmed via Midian’s KL-3 or the new KL-4 programmer. Please reference the KL- 4 manual or the KL-3 manual for setup instructions of the KL-3 software and hardware. From the product selection screen on the KL-3 software, select the VS-1xxx from the list and click OK. -
Page 6: Hardware Alignment
HARDWARE ALIGNMENT This section describes to determine and set the audio levels. Audio Levels Overview: To ensure the best audio quality, the scrambler must be configured to match the audio levels used by the radio. The scrambler uses programmable gain amplifiers to accomplish this. Determining the gain settings for these amplifiers is an involved process, so Midian simplified this process by developing an algorithm that requires the technician to make only four voltage measurements. - Page 7 Programming the Audio Levels: After determining the audio levels at the audio hookup points, it will be necessary to program the scrambler to match these levels. In the programming software, there is a slider control on the Audio Levels Screen for each of the of four audio hookup points.
