STROBE OUT:

Rear panel BNC connector used as:

•External system clock input: pulse frequency = input frequency. The input frequency can be measured.

•5 MHz or 10 MHz frequency reference input for internal PLL.

Phase Locked Loop (PLL)

•Locks either to an external frequency reference at the PLL Ref Input Clk In (5 MHz or 10 MHz selectable) or to its internal reference.

•High accuracy period (frequency) source.

When locked to the internal reference, period accuracy, resolution, and jitter are improved.

When locked to an external frequency reference, the external frequency affects these accuracies.

•Internal triggering of bursts: the internal PLL can replace an external trigger source, while the output period is determined by the startable oscillator.
