TSS200B Telemetry Signal Simulator. SEMCO’s TSS200B is the ideal instrument for telemetry receiver bench testing and pre-mission receiving system checkout. The TSS200B’s calibrated RF output covers 200 MHz to 5250 MHz, provides +5 dBm to -100 dBm outputs and is modulated with an internal user-selectable modulator in all IRIG …SOQPSK is a continuous phase modulation technique that restricts the phase transitions to ±90°, thereby reducing amplitude attenuation [9]. It employs pre modulation pulse shaping of data symbols which enables a bandwidth-efficient transmission with less spectral leakage. These characteristics of SOQPSK are ….
