4.16 Setting Voltage using External DC Input Signal
KP3000GS 155
2. Press the [Osc] soft-key and select [2:Source]. From the opened menu, select [2: VCA].
3.
Set the [Freq], [Wave], and [Gain] items.
4. Supply a DC voltage to the external signal input connector.
5. Turn on the output.
4.16.2 Using External Signal in DC-VCA Mode
In the DC-VCA mode, the setting value of the output DC voltage (DCV) is set according to the
following figure, by using the gain setting value and the voltage of the external DC signal.
DCV (V) = Gain x External DC signal voltage (V)
For the specifications of the gain setting range and the external DC signal input voltage range, see
10.22.2 .
-------- Notes ------------------------------------------------------------------------------------------------------------
 The gain setting value is retained for each of 100 V/200 V ranges and for each of AC/DC
modes.
 Within the same range, the same value is retained for the gain setting value, regardless of the
combination of the signal sources (VCA, EXT, ADD).

When the switching from DC-VCA mode to ACDC mode, the signal source is forcibly set to
INT.
