From: Temporal locking of pulses in injection locked oscillators
Overlapping Allan deviation \(\sigma\) of the TL pulse period (blue curve), which is compared to that of the injected CW signal (red curve). The two measurements were performed sequentially due to the limitation of our frequency counter. Although the injected frequency was 6.3 GHz and the pulse repetition rate was about 899.4 kHz, the Allan deviation of both signals is similar. To obtain a stable trigger to the counter, the phase pulses were converted into amplitude pulses by multiplying the oscillator and the injected signal in an RF mixer. Therefore, the measurement accuracy is limited by the external source.
