ABSTRACT:
The present invention is an apparatus for generating a signal for use in testing the purported sensitivity of a microwave receiving equipment having a noise source (105, 106) for generating a noise signal, first (112), second (114), and third (118) stage microamplifiers connected in series with an attenuator (116) for amplification and adjustment of the power level of the noise signal, a first splitter (120) connected to the output of the third stage amplifier (118), a first power meter (124) connected to a first output of the first splitter (120), a second splitter (130) receiving at its input a microwave carrier signal (127) having a specific power level, a second power meter (134) connected to a first output of the second splitter (132) and a combiner (138) connected to the second outputs of the first and second splitters (120, 130) which provides an output test signal for use in testing the carrier to noise of the microwave receiving equipment.
