Example:
*RST; FREQ:IMOD:LTON PORT,1; UTON GEN, 1
Reset the instrument to create the default channel no. 1. Select
port 1 as a source port for the lower tone, the (previously config-
ured) external generator no. 1 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:LTON
Start source power calibration for the lower tone at the previ-
ously selected source port 1.
SOUR:POW:CORR:IMOD:UTON
Start source power calibration for the upper tone at the previ-
ously selected source port 3.
CORR:POW:IMOD:ACQ
Start receiver power calibration at the previously selected
receive port 2.
CALC:PAR:SDEF 'IM_Meas', 'IP3UI'
Create a new channel no. 2 and a trace named 'IM_Meas'.
Select the upper 3rd-order intercept point at the DUT input as a
measured quantity.
Usage:
Event
Manual operation: See "Start Cal Sweep" on page 592
SOURce<Ch>:POWer:CORRection:IMODulation:PORT <SourceForRecCal>
Selects the source port for the receiver power calibration of an intermodulation mea-
surement. An external generator must be configured before the generator port is avail-
able (SYSTem:COMMunicate:RDEVice:GENerator<Gen>:DEFine).
Suffix:
<Ch>
.
Channel number
Parameters:
<SourceForRecCal> String parameter to identify the source port:
'COMBINER' – combiner output
'PORT <n>' – analyzer port n (separate port no. by blank, e.g.
'PORT 4')
'GEN <n>' – external generator port n (separate port no. by
blank, e.g. 'GEN 1')
*RST: 'COMBINER'
