Keysight EXG and MXG X-Series Signal Generators User’s Guide 237Basic Digital Operation for N5172B/82B with Options 653/655/656/657Multiple Baseband Generator SynchronizationIf the trigger settings are other than what the BBG synchronization feature supports, the featurechanges the trigger settings to what is shown on page 234. When this change occurs, the KeysightMXG/EXG generates a settings conflict error to alert you to the changes. To avoid the errorgeneration, appropriately configure the trigger settings prior to selecting a signal generator as themaster or slave.The system trigger propagates in the same manner as the synchronization pulse initiated by themaster (see System Synchronization). So if it is not turned off during changes to thesynchronization parameters, it can cause a false In Sync status.The signal generator does not reset the trigger parameters when the multiple BBG synchronizationfeature is turned off. To play waveforms after disabling the feature, you must either set the triggertype to Free Run or provide a trigger to start the waveform play back.Equipment SetupFigure 8-29 Multiple Baseband Synchronization SetupConfiguring the SetupSet the Common ParametersPerform the following steps on all signal generators:1. Set the frequency of the carrier signal.2. Set the power level of the carrier signal.3. Select the desired waveform (see page 155).Do not turn the Dual ARB on.4. Except for triggering, set the desired waveform parameters such as markers and sample clock.There can be 1 to 15slaves in a setup.If not using the Trigger key, provide an external triggersource.
