:OUTPut[<n>]:IMPedance
:OUTPut[<n>]:LOAD
Syntax :OUTPut[<n>]:IMPedance {<ohms>|INFinity|MINimum|MAXimum}
:OUTPut[<n>]:LOAD {<ohms>|INFinity|MINimum|MAXimum}
:OUTPut[<n>]:IMPedance? [MINimum|MAXimum]
:OUTPut[<n>]:LOAD? [MINimum|MAXimum]
Description Set the output impedance of the output connector of the specified channel.
Query the output impedance of the output connector of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<ohms> Integer 1Ω to 10kΩ 50Ω
Explanation  When [<n>] is omitted, the commands set and query the related parameters
of CH1 by default.
 <ohms> denotes setting the output impedance of the output connector of the
specified channel to a specified value within the range available; INFinity
denotes setting the output impedance of the output connector of the specified
channel to HighZ.
 The output impedance setting affects the output amplitude and DC offset. If
the actual load is different from the specified value, the voltage level displayed
will not match the voltage level of the item under test. To ensure correct
voltage level, make sure that the load impedance setting matches the actual
load.
Return Format The query returns the output impedance in scientific notation with 7 effective
digits, for example, 1.000000E+02 which denotes that the output impedance is
100Ω. If the output impedance of the output connector of the specified channel is
set to INFinity, the query returns 9.900000E+37.
Example :OUTP1:IMP INF /*Set the output impedance of the output connector of CH1 to
HighZ*/
:OUTP1:IMP? /*Query the output impedance of the output connector of
CH1 and the query returns 9.900000E+37*/
:OUTP1:LOAD 100 /*Set the output impedance of the output connector of CH1
to 100Ω*/
:OUTP1:LOAD? /*Query the output impedance of the output connector of
CH1 and the query returns 1.000000E+02*/
