The Picosecond Advantage:
This prescaler requires no adjustments to achieve synchronization. The measured timing jitter is a phenomenally low 0.8 ps rms, which includes the combined jitter of the countdown and the scope.

Description:
Our Model 5650 Trigger Countdown is a prescaler that extends the range of frequency counters to 16 GHz. It may be used as an inexpensive divider to allow digital sampling oscilloscopes to trigger on 16 GHz signals. Six models are available with division ratios of 2, 4, 8, 16, and 32.
