MXA unresponsive to SCPI commands while "wait for trigger"

I'm programming an application in which RF pulses are manually sent using a PSG. The pulse generator sync output of the PSG is connected to three MXAs trigger input, those are configured in zero span mode.


I'd like to fetch the traces on the MXA after the pulse has been sent. Nevertheless the MXAs change to "wait for trigger" very fast and it seems that they are unresponsive to SCPI commands in that state.


If I set free run triggering in the MXA my software fetches the traces without problems but I need to use external trigger to capture the RF pulses.


What shall I do so the MXAs are responsive to my SCPI commands and I can retrieve the traces?
