4.7 Synchronize the Output with External Signal
The EC1000SA is equipped with an externally synchronized oscillation function. The software PLL
function synchronizes the output frequency to the frequency of the external synchronization TTL signal.
The output frequency can be synchronized to any frequency from 40 Hz to 500 Hz. The synchronization
phase difference cannot be set.
Select either external signal synchronous (EXT) or line synchronous (LINE) as the external sync signal
source.
When line synchronous is selected, synchronization is with the power source frequency.
