LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
The AN/TMQ-38 Meteorological Measuring Set (MMS), as shown in Figure l-l, consists of the following major
components: MARWIN Processor (Al), Radio Direction Finding (RDF) Unit (A8) including the Control Display
Unit (CDU) (A9), Digital Communications Terminal (DCT) (A3), Printer (A2), NAVAID Antenna Set (A6), Power
Supply Unit (A4), 24 VDC Power Supply (A10), 17 System Interconnect Cables (W1-W3, W5-W14, W16, W18-
W20), 7 Transportation Cases, and RDF Tripod Carrying Bag.
Except for the RDF Tripod, all of the components of the MMS are stored and transported in seven reusable
transportation cases. Case latches and handles are designed for use with heavy gloves. Each case is non-
hygroscopic and non-temperature sensitive and utilizes foam cushioning with equipment contour cutouts to shield
the equipment from the effects of shock and vibration. Cases are rain proof and contain an over/under pressure
equalizing valve allowing the safe air transportation of the system to an altitude of 40,000 feet.
Power and signal connections between the major components of the MMS are accomplished by seventeen
cables which are stored in the transportation cases when not in use. The cables are constructed with standard
military connectors, and the shields are terminated with EMI cable sealing backshells. Operating power is
converted/conditioned by the Power Supply Unit (PSU) and 24 VDC Power Supply from primary 120 VAC, 50/60
HZ, single phase and 28 VDC input power.
