Input Trigger Channel (Trigger)
selects the channel to be used to trigger a measurement. You can trigger off any configured measurement channel. You can also set up a custom input channel configuration and trigger off of a logical channel that is not mapped to a measurement channel.
The available input trigger channels depend on the Input Channel configuration. For standard configurations, the choices in the drop-down menu will reflect the currently configured measurement channels (1-n). For custom configurations, inputs that are mapped to measurement channels are numerical (1-n), and logical channels that are not mapped to this measurement are designated with an "L" (for "Logical") prefix (L1-Ln). These logical channels are useful for triggering on one channel but measuring on other channels.
