Chapter 3 Features and Functions
Output Configuration
• Remote Interface Operation:
VOLTage {<amplitude>|MINimum|MAXimum}
Or, you can set the amplitude by specifying a high level and low level
using the following commands.
VOLTage:HIGH {<voltage>|MINimum|MAXimum}
VOLTage:LOW {<voltage>|MINimum|MAXimum}
You can also use the APPLy command to select the function, frequency,
amplitude, and offset with a single command.

DC Offset Voltage

The default offset is 0 volts for all functions.
• Limits Due to Amplitude: The relationship between offset voltage and
output amplitude is shown below. Vmax is the maximum peak voltage
for the selected output termination (5 volts for a 50Ω load or 10 volts
for a high-impedance load).
|Voffset| < Vmax –
If the specified offset voltage is not valid, the function generator will
automatically adjust it to the maximum dc voltage allowed with the
amplitude specified.
• 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 ohms to "high impedance", the offset voltage displayed on the
function generator's front-panel will double to 200 mVdc (and no error
will be generated). If you change from "high impedance" to 50 ohms,
the displayed offset will drop in half. See "Output Termination" on
page 57 for more information.
