PROGRAMMABLE AC/DC POWER SOURCE 228
10.4 Signal Source
KP3000GS
Signal source INT, VCA, SYNC, EXT, ADD
Description
INT Uses the internal signal source.
Sets the output voltage, output waveform, frequency, output on phase, and output
off phase by using the panel or the external interface such as USB.
Fixed to INT in the Sequence and Simulation.
VCA Uses the internal signal source.
Controls the output voltage setting of the internal signal source with the DC
signal which is input to the external input terminal. The output voltage setting
cannot be set from external interfaces such as the panel or USB. All conditions
except for output voltage setting are same as INT.
Cannot be selected in the AC+DC mode.
SYNC Uses the internal signal source.
Synchronizes the frequency of the internal signal source with the signal (EXT)
from the external synchronization signal input terminal (also used as the external
input terminal) or the power supply input frequency (LINE) of the product. The
frequency setting cannot be set from external interfaces such as the panel or USB.
All conditions except for output frequency setting are same as INT.
Cannot be selected in the DC mode.
EXT
Uses the external signal source.
Amplifies the signal from the external input terminal by the specified gain
(variable), and outputs it.
Cannot be selected in the DC mode.
ADD
Uses both the internal and external signal sources.
Amplifies the signal from the external input terminal by the specified gain like
EXT, and adds the internal signal source component to it.
Cannot be selected in the DC mode.
