48Programming ReferenceSCPI Instrument Command ListSpecified Limits 0.1 Ω to 1 MΩDescription Use this command to set the expected load impedance of the deviceunder test at the OUTPUT connectors. If you have a non-50 Ω load, theoutput levels at the device under test will not be the levels you programor set via the front panel unless you set the expected load using thiscommand.Example To set the expected load impedance:Command :OUTP[1]:POLLong :OUTPut[1]:POLarityForm Set & QueryParameter NORMal | INVerted*RST value NORMDescription 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 & QueryParameter NumericParameter 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 typical3.8V 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 NORMInverted signal at OUTPUTNormal signal at OUTPUT
