240 Keysight EXG and MXG X-Series Signal Generators User’s GuideBasic Digital Operation for N5172B/82B with Options 653/655/656/657Multiple Baseband Generator SynchronizationMaking Changes to the Multiple Synchronization Setupand Resynchronizing the Master/Slave SystemIf any changes are made to the master/slave parameters or a signal generator (slave unit) is addedto the system, the system must be resynchronized even if In Sync appears in the Status portionof the display.1. Turn off the trigger source. If using the Trigger key, there is nothing to turn off.If the trigger source is on and provides a continuous pulse stream, it may cause the signalgenerators to incorrectly display In Sync as the status after pressing the Listen for Syncsoftkey.2. On each of the signal generators, press Mode > Dual ARB > ARB Off On to Off.If a signal generator(s) has the Dual ARB on during changes, signal generators further in thechain may incorrectly display In Sync after pressing the Listen for Sync softkey.3. On each of the signal generators, press ARB Setup > More > Multi–BBG Sync Setup.4. Make the changes in the Multi–BBG Sync Setup menu.Out Of Sync appears as the status message.5. On each of the slave signal generators, press Listen for Sync.6. Ensure that all of the slaves’ Status show Waiting for Sync. If In Sync shows as thestatus, perform the following steps:a. Check that the PATT TRIG to EVENT 1 cables are properly connected on the rear panel.A disconnected cable can cause a false In Sync status.b. If the cables are connected, perform steps 1 and 2.c. Press Listen for Sync and ensure that Waiting for Sync appears as the status.7. On the master signal generator, press Sync Slaves.8. Verify that In Sync appears as the status on all master/slave signal generators.9. Perform the process “Trigger and Play the Waveform” on page 239.
