PROGRAMMABLE AC/DC POWER SOURCE 162
4.18 Synchronizing the Output Frequency with the Power Line or
the External Signal
When you select SYNC for the signal source, you can synchronize the frequency of the internal
signal source with the power line or the external signal. The icon
is displayed when the
internal signal source is synchronized with the external signal. The icon is displayed when
the synchronization is not performed. The measured synchronization frequency value is displayed in
the measured value area on the screen. See
10.11 for the measurement specification of the
synchronization frequency and 10.22.1 for the interface specification of the external
synchronization signal.
--------
Notes ------------------------------------------------------------------------------------------------------------
 The output on phase/off phase setting (3.4.6) is valid in SYNC also.
 You cannot make the output on if synchronization is not performed.
 When the switching from AC-SYNC or ACDC-SYNC mode to DC mode, the signal source is
forcibly set to INT.

 Operation procedure
1. If you want to synchronize the internal signal source with the external signal, input the
synchronization signal by using the external signal input connector. If you want to synchronize
it with the power line, this step is not necessary.
2.
Press the [Osc] soft-key and select [3:SYNC] from [2:Source].
