Resolution	14 bit
Output drive	50 Ω
Sampling rate	125 MHz
Rise/fall time	8.8/9.6 ns
Bandwidth	~35 MHz

Trigger Input

The Pulse Streamer 8/2 has one external trigger input, which can be enabled by software. By default, the Pulse Streamer is automatically rearmed after a sequence with a finite number of n_runs has finished. That means if another trigger occurs after a sequence has finished, the sequence will be re-triggered again. On the contrary, if a trigger occurs while a sequence is streamed, it will be discarded. We recommend, not to exceed 1 kHz as an external retrigger frequency. Information about how to configure the trigger functionality of the Pulse Streamer can be found in the Running pulse sequences section.

Electrical characteristics:

Trigger-to-data (mean)	64.5/65.5ns
Trigger-to-data (rms jitter)	2.3 ns

External Clock Input

The Pulse Streamer 8/2 has one input that can receive an external 125MHz or 10 MHz reference clock. Further information about how to set the clock-source of the Pulse Streamer can be found in the Using an external clock section. Before using the external clock the first time, please contact support@swabianinstruments.com
