DC Offset Voltage | Agilent Technologies U2761A instruction

Features and Functions

Remote Interface Operation

VOLTage {<amplitude>}

Or, you can set the amplitude by specifying a high level and low level using the following commands.

VOLTage:HIGH {<voltage>}

VOLTage:LOW {<voltage>}

You can also use the APPLy command to select the function, frequency, amplitude, and offset.

DC Offset Voltage

The default offset is 0 V for all functions.

Limits Due to Amplitude

The relation between the offset voltage and output amplitude is shown below. Vmax is the maximum peak voltage for the selected output termination (5 V for a 50 Ω load or 10 V for a high-impedance load).

If the specified offset voltage is not valid, the U2761A will automatically adjusts it to the maximum DC voltage allowed with the specified amplitude.
