RFmxVnaMXTriggerMode Enumeration

VNA waits for asserting only one instance of trigger before acquiring all data points for the configured measurements in the RFmxVNA Signal namespace.

All data points that share a source port are acquired after VNA asserts one instance of the trigger. For example, when you measure S11 and S22 at 10 frequency points using a 2-port VNA, after asserting the first instance of trigger, the device completes all acquisitions that require VNA port 1 as source. Upon asserting the second trigger, the device completes all acquisitions that require VNA port 2 as source.

VNA acquires only one data point for each trigger instance that it asserts. For example, when you measure S11 and S22 at 10 frequency points using a 2-port VNA, the device will assert a total of 20 trigger instances to complete all acquisitions.

When SweepType is set to Segment, all data points within a segment that share a source port are acquired after VNA asserts one instance of the trigger. For example, when measuring S11 and S22 using a 2-port VNA across 2 frequency segments, each containing 4 frequency points, after the first trigger is asserted, the device completes all acquisitions in the first segment that require VNA port 1 as source. Upon asserting the second trigger, the device completes all acquisitions in the second segment that require VNA port 1 as source. On the third trigger, the device completes all acquisitions in the first segment that require VNA port 2 as source. On the fourth trigger, the device completes all acquisitions in the second segment that require VNA port 2 as source. Therefore, a total of 4 triggers are required to complete all acquisitions of both segments for both source ports.
