For the very latest specifications visit www.aeroflex.com The RD-301A Weather Radar Professional test set satisfies simulation requirements for new generation noncoherent radar systems Avionics RD-301A Weather Radar Test Set • Automatic transmitter magnetron frequency tracking and digital read-out • Internal/external modulation for simulating target scintillation for turbulence detection radars • Transmitter peak pulse measurements • Built-in IF sweep generator from 20 to 70 MHz and marker generator for IF and AFC testing • Radar UUT sensitivity testing • Two-year limited warranty Aeroflex is a leader in the design, manufacture and marketing of Avionics test systems. The RD-301A will respond to radar transmitter pulse widths of 50 ns to 30 ìs in a frequency range of 9295 to 9500 MHz. All RF tests and measurements can be accomplished by connecting the RD-301A to the unit under test with the use of the supplied calibrated in line cable, waveguide coupler and dummy load. Tracking System The RD-301A tracking system enables the test set to automatically acquire and track the transmitter frequency. This basic feature eliminates the need for constant re-tuning to compensate for transmitter or signal generator drift. Heterodyne Monitor Output The Heterodyne Monitor Output provides a convenient oscilloscope manufacturer display of the frequency and duration of modes, identifying the location and magnitude of phase pulling within the magnetron pulse. Effective Peak Power (EFF) Effective Peak Power (EFF), displayed on the Panel Meter located on the front panel, quantifies the effects of phase modulation in the magnetron replacing the requirement for the use of a supplier of spectrum analyzer. The EFF function allows the operator to choose the optimum tracking frequency in the presence of modes and phase pulling in the magnetron pulse. Using the EFF meter function in conjunction with the heterodyne monitor output verifies the frequency tracking accuracy of the test set, replacing the need for the echo box which is used for AFC centering. Contour Mode The Contour Mode provides for rapid calibration and checking of contour threshold circuits, receiver color and intensity response and sensitivity by means of an additional 0 to 20 dB amplitude boost above the selected output level. Other Features • Heterodyne monitor output • (EFF) Transmitter effective peak pulse power measure ments • Built-in PRF generator and digital read-out
