Set DC Offset Voltage
The default configuration of waveform is a sine wave with DC offset voltage of 0V (terminating at 50Ω) when powering on.
The specific steps for changing DC offset voltage into -150mV are as follows:
1. Press function key F3 until the required soft key border outline illuminates to match the colour of the corresponding
channel. When pressing function key F3 again, you will find that the waveform of parameter described with amplitude and
DC offset has been described with high level (maximum value) and low level (minimum value). Such method for setting
signal limit is very convenient for digital application.
2. Input required DC offset value -150mV with numeric keyboard.

3. Select required unit
Press soft key of corresponding unit. The waveform generator outputs waveform with the displayed DC offset when you
select unit and switch output on. Press mV in this example.
Note: this parameter can also be set with multi-functional control and direction key.
