-2.5 Vpp
Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 You can also use the "Amplitude" (
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]) and
"Offset" (
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:OFFSet) to set the high level and low level.
High Level = Offset + Amplitude/2
Low Level = Offset - Amplitude/2
Return Format
The query returns the waveform low level value in scientific notation, with 7 effective digits. For example,
-1.500000E+00 (the waveform low level value is -1.5 Vpp).
Example
:SOUR1:VOLT:LOW -1.5 /*Sets the low level value of the waveform of CH1 to -1.5 Vpp.*/
:SOUR1:VOLT:LOW? /*Queries the low level value of the waveform of CH1 and the query returns
-1.500000E+00.*/
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:OFFSet
Syntax
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:OFFSet {<voltage>|MINimum|MAXimum}
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:OFFSet? [MINimum|MAXimum]
Description
Sets the waveform offset voltage of the specified channel.
Queries the waveform offset voltage of the specified channel.

Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 The range of the DC offset voltage is limited by "Impedance" (
:OUTPut[<n>]:IMPedance
or
:OUTPut[<n>]:LOAD), "Frequency" ([:SOURce[<n>]]:FREQuency[:FIXed]), and "Amplitude"
(
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]) settings. If the offset value in the
command is greater than the corresponding offset upper limit or smaller than the corresponding offset
lower limit, the waveform offset of the specified channel will be set to the offset upper limit or lower
limit.
 The current DC offset voltage of the instrument is the default value or the offset previously set. When
the instrument configuration (e.g. impedance) is changed, if this offset is valid, the instrument will still
use this offset; otherwise, the instrument would display a prompt message and set the offset to the
offset upper limit of the new configuration automatically.
Return Format
The query returns the waveform offset voltage value in scientific notation, with 7 effective digits. For
example, 1.000000E+00 (the waveform offset voltage value is 1 V
dc
).
Example
:SOUR1:VOLT:OFFS 1 /*Sets the offset voltage of CH1 to 1 V
dc
.*/
:SOUR1:VOLT:OFFS? /*Queries the offset voltage of CH1 and the query returns 1.000000E+00.*/
