It operates by using LNB down converters to the L-Band (950 MHz to 1.8 GHz), and monitoring up link transmissions utilizing an upconverter to the 70 MHz IF (45 MHz to 100 MHz). The resolution bandwidths 10 kHz and 300 kHz provides measurement resolution proportional to the frequency accuracy or span. | It operates by using LNB down converters to the L-Band (950 MHz to 1.8 GHz), and monitoring up link transmissions utilizing an upconverter to the 70 MHz IF (45 MHz to 100 MHz).
