VOLTage Subsystem Introduction
conflict" error.
l
The high limit sets the highest output voltage allowed to be set, including DC Offset and peak amplitude. It is set in
reference to the current
OUTPUT[1|2]:LOAD setting. If the specified LOAD impedance is not present at the instru-
ment's output, then the output limit may not represent the actual voltages at the output connector. For example,
if the output impedance is set to 50 Ω, but the actual load is high impedance, then the actual output peak voltage
may be up to twice the specified limit voltage.
l
Specifying Voltage Units: You can set the output limit voltage only in volts.
l
When VOLTage:COUPle[:STATe] is ON, and VOLTage:LIMit:STATe is ON, voltage limit settings on both channels
affect maximum amplitude and offset voltage settings on both channels. The most restrictive combination of high
and low limits from either channel is used.
[SOURce[1|2]:]VOLTage:LIMit:STATe {ON|1|OFF|0}
[SOURce[1|2]:]VOLTage:LIMit:STATe?
Enables or disables output amplitude voltage limits.
Parameter Typical Return
{ON|1|OFF|0}, default OFF 0 (OFF) or 1 (ON)
Set and enable ±2.5 V output limits on channel 1:
VOLT:LIM:HIGH 2.5
VOLT:LIM:LOW -2.5
VOLT:LIM:STAT ON
l
When this is turned ON, if the present settings of amplitude and offset exceed the limits, then the limits will be dis-
abled. The instrument will generate either a "Settings conflict" error.

Limits are set in reference to the current setting of OUTPut[1|2]:LOAD . If the specified LOAD impedance is not
present at the instrument's output, then the output limit may not represent the actual voltages at the output con-
nector. For example, if the output impedance is set to 50 Ω, but the actual load is high impedance, then the actual
output peak voltage may be up to twice the specified limit voltage.
[SOURce[1|2]:]VOLTage:OFFSet {< offset >|MINimum|MAXimum}
[SOURce[1|2]:]VOLTage:OFFSet? [{MINimum|MAXimum}]
Sets DC offset voltage.
Parameter Typical Return
± 5 VDC into 50 Ω, default 0 +1.0000000000000E-01
Set offset voltage to 100 mV:
VOLT:OFFS 100 mV
