scope:

- This specification covers the requirement for the OA-1208( )/DPN Transmitter Group, Telemetric Data suitable for installation in the AIM-7D, and AIM-7E guided missiles (SPARROW) for use in conjunction with a telemetry system. The OA-1208( )/DPN provides a reliable crystal controlled, single channel, frequency modulated telemetering signal for flight testing of the AIM-7D, and AIM-7E missiles. The electrical variations produced by the missile video, speedgate sweep, and fuzing signals vary the frequency of the radio frequency oscillator, or a subcarrier thereon.

- The equipment covered by this specification is of one type collectively designated as Transmitter Group, Telemetric Data OA-1208( )/DPN, and consists of the following:
