6140t.gif (14145 bytes)GPS/IRIG B Video Synchronizer, Model 6140, is a stand-alone unit designed to synchronize color and/or monochrome video cameras to GPS time or IRIG B serial time code. All cameras genlocked to like units will be precisely synchronized.

The unit consists of a twelve channel GPS receiver, the output of which is used to synchronize an IRIG B time code generator. The IRIG B signal is then used to drive the color and monochrome video sync generators. The 6140 provides a precise IRIG B serial time code output, an RS-170 composite video signal and an RS-170A (NTSC) composite signal with black burst. The unit automatically acquires all in-view satellites upon power up and locks the internal IRIG B time code generator to the GPS time reference. The Video Sync Generators then lock to the IRIG B. Lock status is displayed by LED indicators on the front panel. If the GPS lock is lost the 6140 will automatically switch to an internal clock and continue generating the output IRIG B signal. No discernible change in the IRIG B output or video sync will occur due to this transition.

The 6140 may also be used as a stand-alone unit to generate an IRIG B signal and video synchronization signals. The time-of-year may be set by the user via an included RS-232 port which may also be used to read the GPS/IRIG time. In the event of a power failure the time will continue to advance by automatically switching to a battery backed-up internal clock. The IRIG and video outputs will resume, without resetting, upon reapplication of power.

The 6140 is powered by 9 to 36 Volts DC and includes an active magnetic mount GPS antenna.

IRIG B Video Synchronizer, Model 6140A, is a stand-alone unit designed to synchronize color and/or monochrome video cameras to an applied IRIG B serial time code.  It is identical to the 6140 except it has no GPS receiver but synchronizes to IRIG B only.  All cameras genlocked to like units will be precisely synchronized.  The 6140A provides a precise IRIG B serial time code output, an RS-170 composite video signal and an RS-170A (NTSC) composite signal with black burst.  The unit uses an external IRIG B input signal to synchronize the internal IRIG generator/video timing logic.  Lock status of the IRIG generator and Video Synchronizers is displayed via LED indicators on the front panel. If the external IRIG lock is lost the 6140A will automatically switch to an internal clock and continue generating the output IRIG B signal.  No discernible change in the IRIG B output or video sync will occur due to this transition.

The 6140A may also be used as a stand-alone unit to generate an IRIG B signal and video synchronization signals.  The time-of-year may be set by the user via an included RS-232 port, which may also be used to read the IRIG time.  In the event of a power failure the 6140A will no longer output the serial time code or video sync however the time will continue to advance by automatically switching to a battery backed-up internal clock.  The IRIG and video outputs will resume, without resetting, upon reapplication of power.

The 6140A is housed in a ruggedized aluminum enclosure,  8.5 wide x 10 deep x 2.5 high and is powered by 9 to 36 volts. DC.

High Speed IRIG Processor, Model 6145B, is an accessory to the NAC HSV500 C3 High Speed Video System, which provides for the synchronization of the video field with IRIG time and the insertion of an IRIG time message and other data into the viewed scene.  It detects and demodulates the IRIG B serial time signal, phase locks the video sync to the decoded signal and generates a numeric time message which is inserted into the HSV500 C3 image.

The 6145B includes a Scanline Data Encoder that inserts machine readable data into two scanlines per field.  The position of the encoded scanline data is user selectable.  Encoded data includes Azmiuth, Elevation, Time and five bytes of other user-entered data.  The data can be read by an ITS Model 6142A Dual Mode Video Data Decoder.

Parallel and serial ports provide for the insertion of Azimuth, Elevation and ASCII messages.  Two parallel input and two parallel output ports provide for sensing Azimuth and Elevation data which is routed from the source to other instrumentation such as the ITS Model 6088A.  The 6145B can generate a data strobe or if it detects a strobe from another device will pass it through.

Additionally, Keyboard/RS232 inputs are available which allow the Model 6145B to generate alphanumeric annotation as input from the optional keyboard or from an external terminal or computer via the RS232 port.

The unit is housed in a 13.5 x 9.7 x 2 sheet metal enclosure designed to mount on top of the HSV500 C3 recorder assembly.  It is powered by 115VAC.

High Speed IRIG Processor, Model 6145, is similar to the Model 6145B except that it doesn't contain the Azimuth & Elevation parallel ports or the Scanline encoding function.  It  provides for the synchronization of the NAC HSV500 C3 High Speed Video System with IRIG time and the insertion of an IRIG time message into the viewed scene.  It detects and demodulates the IRIG B serial time signal, phase locks the video sync to the decoded signal and generates a numeric time message which is inserted into the HSV500 C3 image via the Data Mix port.  A single 6145 has the capability of synchronizing and annotating up to four cameras, with identical data inserted into each.

Additionally, Keyboard/RS232 inputs are available which allow the Model 6145 to generate alphanumeric annotation as input from the optional keyboard or from an external terminal or computer via the RS232 port.

The unit is housed in a 13.5" x 9.7" x 2" sheet metal enclosure designed to mount on top of the HSV500 C3 recorder assembly.  A rack mount unit, the Model 6145R is also available, see below. Both are powered by 115VAC.
