External Trig In Setting; Choose Port Speed; Ports Configuration - Teledyne Sierra M6-2 User Manual

Note:
The minimum pulse width requirement is different for "high going" pulses and "low going"
pulses.
If you normally drive the Trig‐IN SMA with 0V and then give it a "high going" pulse, the minimum
pulse width that reliably causes the trigger is 70 ns.
If you normally drive the Trig‐IN SMA with 1‐3V and then give it a "low going" pulse, the
minimum pulse width that reliably causes the trigger is 20 µs.

External Trig In Setting

An external Low or High input signal can cause triggering. Under Setup select External
Trig Setting to choose External Trig In Setting: High Active, Low Active, or Toggle from
High to Low or Low to High once (3.3 V output).

Choose Port Speed

The default speed is Autospeed. You can also select the port speed from the
drop‐down list: 1.5 Gbps, 3.0 Gbps, or 6.0 Gbps.
Note:
If a Port ID check box has no check, the analyzer does not capture any patterns for that port. The
system allocates trace memory for that port to its adjacent port, for example: I1, T1 <‐> I2, T2.
