Multiple Baseband Generator Synchronization
Making Changes to the Multiple Synchronization Setup
and Resynchronizing the Master/Slave System
If any changes are made to the master/slave parameters or a signal generator (slave unit) is added
to the system, the system must be resynchronized even if
In Sync
appears in the
Status
portion
of 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 signal
generators to incorrectly display
In Sync
as the status after pressing the
Listen for Sync
softkey.
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 the
chain 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 the
status, 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
