8-7-8. OUTPut[1|2]:LOAD
Set
Query
Description
Sets or queries the output termination. Two impedance
settings can be chosen, D
EFault (50Ω) and INFinity (high
impedance >10 kΩ).
The output termination is to be used as a reference only. If the
output termination is set
50Ω but the actual load impedance is
not
50Ω, then the amplitude and offset will not be correct.
Note
If the amplitude has been set and the output termination is
changed from 50Ω to high impedance, the amplitude will
double. Changing the output termination from high impedance
to 50Ω will half the amplitude.
If the output termination is set to high impedance, dBm units
cannot be used. The units will default to Vpp.
Syntax
OUTPut[1|2]:LOAD {DEFault|INFinity}
Example
OUTP1:LOAD DEF
Sets the channel 1 output termination to
50Ω.
Query Syntax

Parameter

INF
INFinity
Example
OUTP1:LOAD?
DEF
The output termination for channel 1 is set to 50Ω.
8-7-9. SOURce[1|2]:VOLTage:UNIT
Set
Query
Description
Sets or queries the output amplitude units. There are three
types of units: VPP, VRMS and DBM.
Note
The units set with the VOLTage:UNIT command will be used
as the default unit for all amplitude units unless a different unit
is specifically used for a command.
If the output termination is set to high impedance, dBm units
cannot be used. The Units will automatically default to Vpp.
