About External Trigger

Description

Checks if the PNA is ready for a hardware trigger.

This command is not intended to be used in a dynamic triggering situation where the ready status is constantly changing. Instead, the expected use is a more static situation where you are expecting the PNA to transition from not ready to ready, and then wait for a trigger. The PNA is polled until it becomes ready and then an operation that triggers the PNA is performed.

Note: This command is only supported on the PNA-L, PNA, and PNA-X with DSP5 installed. Any other model will return an error.
