The REFERENCE IN/OUT connector is a BNC female connector. The signal
supplied here by the user is used for phase-locking the internal 10MHz
reference oscillator, and can be an input of 1, 2, 5 or 10 MHz or an output of 10
MHz. The impedance is matched for 50Ω, and requires a level in the range of 0
dBm to +10 dBm ±3 dB.
