CALCulate<n>:MARKer<m>:FUNCtion:TOI[:STATe] <State>
This command initiates a measurement to determine the third intercept point.
A two-tone signal with equal carrier levels is expected at the RF input of the instru-
ment. Marker 1 and marker 2 (both normal markers) are set to the maximum of the two
signals. Delta marker 3 and delta marker 4 are positioned to the intermodulation prod-
ucts. The delta markers can be modified separately afterwards with the
CALCulate<n>:DELTamarker<m>:X command.
The third-order intercept is calculated from the level spacing between the normal mark-
ers and the delta markers.
