The test generator of the DV-300 converter is used to manual tune the regulators. It consists of a square wave
generator whose frequency, offset and amplitude can be set. The output signal of the “Test Generator” can be
set on a programmable analog output.

Figure 6.15.1.1: Test generator output
Gen access Different parameters can be simulated by the test generator. The parameter concerned
then has the value of the generator output.
Gen frequency Output frequency of the generator in Hz.
Gen amplitude Amplitude of the square-wave signal produced by the generator in percent.
Generator offset Offset of the generator in percent.
The generator output consists of the addition of Gen amplitude and Generator offset.
