ranges are neither needed for intermodulation products at the DUT input (as those are measured
in the RF range) nor for the receiver calibration (as a source power calibration will be performed at
the receiving port).
<Ch>
Channel number
<pt>
Port number This suffix is ignored; the analyzer calibrates the ports that are selected
as source ports for the lower and upper tone of the intermodulation measurement,
respectively ([SENSe<Ch>:]FREQuency:IMODulation:LTONe and
[SENSe<Ch>:]FREQuency:IMODulation:UTONe).

Command
Types
Device-specific, no query
Example:
*RST; FREQ:IMOD:LTON PORT,1; UTON PORT, 3
Reset the instrument to create the default channel no. 1. Select port 1 as a source
port for the lower tone, port 3 as a source port for the upper tone.
FREQ:IMOD:REC 2
Select port 2 as a receiver port.
FREQ:STAR 1GHZ; STOP 2GHz
Define a suitable sweep range to ensure that the analyzer can measure all
intermodulation products.
SOUR:POW:CORR:PMET:ID 1
Select power meter no. 1 (previously configured in the External Power Meters dialog
and properly connected) for the RF source calibration.
SOUR:POW:CORR:IMOD:SPOR
Start source power calibration for the lower and upper tone port (previously selected
source ports 1 and 3).
CORR:POW:IMOD:RPOR:ACQ
Start receiver power calibration at the previously selected receive port 2.
CALC:PAR:SDEF 'IM_Meas', 'IP3UI'
Create a new trace named 'IM_Meas'. Select the upper 3rd-order intercept point at the
DUT input as a measured quantity.
DISPlay:WINDow1:TRACe2:FEED 'IM_Meas'
Display the newly created trace in diagram area no. 1
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:UTONe[:ACQuire]
[Deprecated command, replaced by
SOURce<Ch>:POWer<Pt>:CORRection:IMODulation:SPORts[:ACQuire]]
Starts the source calibration for the upper tone port (2
nd
legacy power calibration step for intermodulation
measurements), stores and applies the calibration data. The external power meter used is selected via
SOURce<Ch>:POWer<Pt>:CORRection:PMETer:ID.
This command will perform a calibration only at the upper tone frequency. If the intermodulation
measurement is combined with a mixer measurement the calibration will be performed at the RF range of
the upper tone frequency only. During this calibration the lower tone port of the intermodulation
