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 FSVA/FSV input.
Marker 1 and marker 2 (both normal markers) are set to the maximum of the two sig-
nals. Marker 3 and marker 4 are placed on the intermodulation products.
The R&S FSVA/FSV 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 3.3.5.9, "Measuring the
Third Order Intercept Point (TOI)", on page 404.

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.
