Same as IM<order><side>O but in this case the intermodulation product is displayed in
dBc units relative to the measured lower tone level at the DUT output ("Lower Tone at
DUT Out").
The relative result is often termed "intermodulation suppression".
Remote command:
CALCulate<Ch>:PARameter:MEASure
CALCulate<Ch>:PARameter:SDEFine
Intercept Point tab
Allows you to select intermodulation products as measured quantities.

Intercept Point at DUT output
●
<order> defines the order of the intercept point. Possible values are 3, 5, 7, or 9.
●
<side> defines the position of the intercept point relative to the lower and upper
tones.
– The Lower intercept points are measured at frequencies below the lower tone.
– The Upper intercept points are measured at frequencies above the upper tone.
– The Minor intercept point denotes the lower or upper intercept point, whichever
is smaller. It reveals the worst-case performance of the DUT.
●
<DUT port> defines the reference port for the intercept point calculation. Possible
values are O for the DUT output port and I for the DUT input port.
Both values differ by the attenuation of the lower tone signal upon transmission
through the DUT; see "Intermodulation quantities" on page 269.

Main Tone tab
Allows you to select the upper/lower tone at DUT input/output as measured quantities.
