:OUTPut Commands 
 
The :OUTPut commands is used to set and query the information related to the channel output and sync 
signal, including setting and querying the channel output state, output polarity, output impedance, output 
mode and gate polarity as well as setting and querying the output state, output polarity and delay time of 
the sync signal. 
Command List: 
  :OUTPut[<n>]:IMPedance

  :OUTPut[<n>]:POLarity 
  :OUTPut[<n>][:STATe] 
  :OUTPut[<n>]:SYNC:POLarity 
  :OUTPut[<n>]:SYNC[:STATe] 
  :OUTPut[<n>]:VOLLimit:HIGH

: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   
Sets the output impedance of the output connector of the specified channel. 
Queries the output impedance of the output connector of the specified channel. 
 
Parameter 
 
Remarks   
  When [<n>] is omitted, the commands set and query the related parameters of CH1 by default. 
  The parameter <ohms> denotes setting the output impedance of the output connector of the specified 
channel to a specified value within the range available. The parameter 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, then the displayed voltage level will not match the voltage level of the 
components under test. To ensure a correct voltage level, ensure that the load impedance setting must 
match the actual load. 
 
Return Format 
The query returns the output impedance in scientific notation, with 7 effective digits. For example, 
1.000000E+02 denotes that the output impedance is 100 Ω. If the output impedance of the output 
connector of the specified channel is set to INFinity, the query returns 9.900000E+37.
