MATLAB control X410 trigger port

How can I use MATLAB to control the X410 so that while it is transmitting the signal, the Trigger In/Out port on the device sends a trigger signal, so that the spectrum analyz

The Trigger In/Out port isn't supported, unfortunately.

The alternative would be to use Time Synchronized Operations. It should be possible to configure the basebandTransmitter to transmit at a specified time, synchronised to the pulse per second (PPS) signal. As long as you can synchronise the spectrum analyzer to the same signal, you may be able to figure out a way to synchronise the two.

For example (untested)

1. Carefully read the documentation and examples for Time Synchronized Operations.
2. Configure a radio configuration in the radioSetupWizard to use an external PPS signal.
3. Synchronise the radio to the PPS signal using setTimeNextPPS and getRadioTime, see example Reset Radio Time on Next PPS Signal.
4. Schedule a transmission at time N (synchronised to the PPS), see example Transmit Data at Scheduled Time with Baseband Transmitter.
5. Ensure Spectrum Analyzer is triggered by same PPS signal.
