Output Configuration
l Setting the high and low levels also sets the waveform amplitude and offset. For example, if you set the high level
to +2 V and the low level to -3 V, the resulting amplitude is 5 Vpp, with a -500 mV offset.
l A DC signal's output level is controlled by the offset voltage (DC Offset Voltage). The DC level may be between ±5 V
into a 50 Ω load or ±10 V with a high-impedance load.

DC Offset Voltage
The default offset is 0 V for all functions.
l Limits Due to Amplitude: The relationship between offset voltage and output amplitude is shown below. The peak
output voltage (DC plus AC) cannot exceed the instrument output rating (±5 V into 50 Ω load, or ±10 V into an
open circuit).
l The relationship between 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).
|Voffset| < Vmax - Vpp/2
If the specified offset voltage is not valid, the instrument will adjust it to the maximum DC voltage allowed with the
specified amplitude. From the remote interface, a "Data out of range" error will also be generated.
l Limits Due to Output Termination: The offset range depends on the output termination setting. For example, if
you set offset to 100 mVDC and then change output termination from 50 Ω to "high impedance," the offset volt-
age displayed on the front panel doubles to 200 mVDC (no error is generated). If you change from "high imped-
ance" to 50 Ω, the displayed offset voltage will be halved. See OUTPut[1|2]:LOAD for details. Changing the output
termination setting does not change the voltage present at the output terminals of the instrument. This only
changes the displayed values on the front panel and the values queried from the remote interface. The voltage
