DUAL COMMUNICATION SPEED ADAPTIVE BASEBAND SWITCHING PHASE SHIFT KEYING APPARATUS |
摘要 |
PURPOSE: A dual communication speed adaptive baseband switching phase shift keying apparatus is provided, which can perform a phased verification between switch modules by providing a bypass path between switch modules, and can perform an accurate test using a low pass filter and a band pass filter. CONSTITUTION: A baseband control apparatus(4) is constituted so that it receives a baseband signal input from a baseband signal processing apparatus(1) and a ranging signal a simulated remote control command signal from a waveform generation apparatus(2) and then applies them to a upward modulation apparatus(5), and provides a signal made by demodulating an RF signal received from a satellite in a downward demodulation apparatus(6) to a frequency counter(3) and on the other hand applies a part of the demodulated signal to the baseband signal processing apparatus.
