Programming Reference
SCPI Instrument Command List
Specified Limits
0.1
Ω
to 1 M
Ω
Description
Use this command to set the expected load impedance of the device
under test at the OUTPUT connectors. If you have a non-50
Ω
load, the
output levels at the device under test will not be the levels you program
or set via the front panel
unless
you set the expected load using this
command.
Example
To set the expected load impedance:
Command
:OUTP[1]:POL
Long
:OUTPut[1]:POLarity
Form
Set & Query
Parameter
NORMal | INVerted
*RST value
NORM
Description
Use this command to invert the signal at the OUTPUT.
Example
To invert and re-invert the signal:
Command
:CURR[1]
Long
[:SOURce]:CURRent[1][:LEVel][:IMMediate][:AMPLitude]
Form
Set & Query
Parameter
Numeric
Parameter suffix
A
with engineering prefixes.
*RST value
20 mA (50
Ω
into 50
Ω
)
Specified Limits
10 V Outputs (from high Z into short): max. 400 mA typical
3.8V Outputs (50
Ω
into short): max. 152 mA typical
:OUTP:IMP:EXT 47.6OHM
Set load impedance at OUTPUT to 47.6
Ω
:OUTP:POL INV
:OUTP:POL NORM
Inverted signal at OUTPUT
Normal signal at OUTPUT
