7.3.7.2 SYNC Status Display
A "Synced" status field will be displayed in
This field will toggle with the regular "Ready/Enabled/Fault" status field also shown in this
location. The "Synced" status will be shown every 3 seconds for 1 second in place of the
"Ready/Enabled/Fault" field. When the PLL is not locked to the external source, the unit will
display an "Unsynced" status in Orange.
It is not recommended to enable the unit when it has not locked or synchronized to the
external source because the frequency may be unknown.
7.3.7.3 Sync Operation Settings
The AFX allows precise configuration of the synchronization parameters to optimize
performance for each application. The parameters are:
1 Phase shift: Defines a fixed phase shift between phase A waveform generation and
the external sync source. Used to calibrate any phase difference between the sync
signal and the power source output on phase A.
Command: SOURce:SYNChronize:PHASEshift
Speed: Allows accelerating the speed of the internal synchronization engine (PLL) in
2
case the external sync source is not constant and presents periodic or continuous
