PROGRAMMABLE AC POWER SOURCE 262
10.22 External Signal Input
The external signal input works differently depending on the selection of the signal source.
10.22.1 External Synchronous Signal Input (Signal Source SYNC only)
This is the signal to synchronize the frequency of the internal signal source with the one of the
external signal source.
When the signal source is SYNC, you can select whether to synchronize with this external signal
input or the power input frequency of the product. When synchronizing with the power input
frequency, no signal input is needed.

10.22.2 Voltage Setting Signal Input (Signal Source VCA only)
This is the signal to set the output voltage amplitude of the internal signal source (DC input).
Output voltage (Vop) = Voltage setting signal (Vdc) x Gain (Vop/Vdc)
Example 1) For the AC mode, signal source = INT, the gain of 100.0, and the voltage setting
signal input of 1 Vdc, the output voltage is 100 Vop
Example 2) For the AC mode, signal source = INT, the gain of 141.4, and the voltage setting
signal input of 1 Vdc, the output voltage is 141.4 Vop(=100 Vrms)
