Hi,
I am using Agilent N5182A MXG Signal Generator with AWGN injection, controlled by matlab via lan connection.
I want to use C/N noise mode.
Because of the fact I’m using multiple baseband generator synchronization feature, I can’t use the Trigger Type to be Continuous + Free (page 319 on the SCPI Command Reference)
The problem is that when I’m changing C/N ratio, the signal stops playing and I need to resend a trigger command to the SG.
This scenario creates about 200ms in which no signal is being played. My application can’t stand this long time of no signal playing.
I checked the what happens when using FREE mode (with no multiple baseband generator synchronization feature) and I saw that the time of no signal shrinks to about only 5ms.
I’m wondering is there a way to achieve this kind of retriggering time while using multiple baseband generator synchronization feature.
Thanks in advance.

When the AWGN setting are changed (on/off, C/N ratio format, C/N Ratio) the master source stops the signal and restarts it, which ends the synchronization of the MXGs.
This can’t be changed. The additional time is required to get the sources resynchronized again.
We have discussed this with the design team and we know of no method around the need to stop the modulation.
