TOI
Opens a submenu and activates the measurement of the 3rd order intercept point.
A two-tone signal with equal carrier levels is expected at the R&S ESR input. Marker 1
and marker 2 (both normal markers) are set to the maximum of the two signals. Marker
3 and marker 4 are placed on the intermodulation products.
The R&S ESR calculates the third order intercept point from the level difference
between the first 2 markers and the markers 3 and 4 and displays it in the marker field.
For general information on measuring the TOI see Chapter 6.1.1.11, "Measuring the
Third Order Intercept Point (TOI)" , on page 330.

Marker 1 / Marker 2 / Marker 3 / … Marker 16,/ Marker Norm/Delta ← TOI
The "Marker X" softkey activates the corresponding marker and opens an edit dialog
box to enter a value for the marker to be set to. Pressing the softkey again deactivates
the selected marker.
If a marker value is changed using the rotary knob, the step size is defined via the
Stepsize Standard or Stepsize Sweep Points softkeys.
Marker 1 is always the reference marker for relative measurements. If activated, mark-
ers 2 to 16 are delta markers that refer to marker 1. These markers can be converted
into markers with absolute value display using the "Marker Norm/Delta" softkey. If
marker 1 is the active marker, pressing the "Marker Norm/Delta" softkey switches on
an additional delta marker.
