The system as a whole had eight of these samplers, referred to at the time as separators. Each output a pulse of up to 3.5 µs. A fixed delay was added in each sampler, such that channel 2's pulse was output about 5 µs after the one from channel 1. This resulted in a "chain" of pulses over one complete cycle of the master clock. A separate "sync pulse" of 20 µs was added in front of channel 1 to allow clock recovery. The pulse chain from the encoders is amplified and sent to the transmission magnetron which produces pulses at the selected frequency.
