Two Channel GPS Synchronized IRIG Generator/Video Inserter

6055C-2G - Instrumentation Technology Systems (ITS)

Two Channel GPS Synchronized IRIG Generator/Video Inserter, Model 6055C-2G provides for the insertion of alphanumeric messages, date/time and countdown clock, into two, asynchronous, RS-170, NTSC, PAL or S-Video signals. The unit includes a 12 channel GPS receiver that automatically acquires all in-view satellites upon power up and locks an internal IRIG B time code generator to the GPS time reference. The time message may be display in Julian or Gregorian format as selected by the operator. Annotation, positioning of the time message and positioning of the alarm messages can be done via the keyboard and/or the RS-232 or Ethernet ports. The IRIG time may also be transmitted over the RS-232 and Ethernet ports upon command from the keyboard or either port. Sixteen discrete control inputs, eight per channel, are used to enable the alarm/event messages with either a TTL level or a contact closure. The time reference is user selectable as GPS or IRIG. A loss of the selected reference input causes the 6055C-2G to automatically switch to an internal real time clock. If it is desired to operate the unit without GPS or IRIG B input, this clock may be set by the user with the keyboard or via the RS-232 or Ethernet port. The Countdown Clock is set via the keyboard or remotely and controlled by two discrete TTL inputs.
