5.6.3. Measuring Carrier Frequency — TX
Typically it will not be necessary to measure the transmit carrier frequency. Starlink
transmit carrier is derived from a very stable 0.1 ppm OCXO (ovenized controlled crystal
oscillator) and is factory calibrated to an ovenized frequency reference.
However if it is required to measure the carrier frequency this may be achieved by
entering the factory calibration menu tree. Here is how:
1. Connect a 30 dB, 5 Watt or greater RF attenuator to the transmitter output.
2. Connect a frequency counter capable of 0.1ppm or better accuracy at 1 GHz to
the rf attenuator.
3. Connect AC power to the SL9003Q transmitter unit.
4. Following the “Factory Calibration” menu tree of 4.2C, navigate to the “QAM
Modem”, and enter the “OCXO” screen. Enable “CW Mode” to “ON”. This will
disable modulation on the carrier so that the carrier frequency may now be
measured.
5. Measure the frequency. Set the “CW Mode” to “OFF”.
