DC Offset Voltage

Set the dc offset voltage.

Limits Due to Output Termination: The offset limits are determined by the current output termination setting. For example, if you set the offset to 100 mVdc and then change the output termination from 50 Ω to "high impedance", the offset voltage will double to 200 mVdc (and no error will be generated). If you change from "high impedance" to 50 Ω, the displayed offset will drop in half.
You can also set the offset by specifying a high level and low level. For example, if you set the high level to +2.46 volts and the low level to -2.5 volts, the resulting amplitude is 2.5 Vpp (with an offset voltage of -20 mV).

To set the High Level, click the Amplitude drop-down arrow and select High Level:

To set the Low Level, click the Offset drop-down arrow and select Low Level:

BenchVue Tip: You can quickly increment or decrement a numeric value using the mouse wheel. Click once in a number entry field and then scroll the mouse wheel up or down.
