2-tone 3rd-order Intermodulation
Distortion
By inputting two different frequency CW signals (desired waves),
two-tone third-order intermodulation distortion is generated close to
the desired waves according to non-linear characteristics of Device
Under Test (DUT). Then, Third Order Intercept (TOI) is calculated
from the two-tone third-order intermodulation distortion.

Limit Line
At the spectrum display (frequency domain), two limit lines are set
and evaluation is performed based on these set lines. Either Upper
Limit or Lower Limit can be selected. The line settings set the
frequency/level of the crossover point sequentially from the lowest
frequency. Up to 100 crossover points can be set. (In the diagram
below, Limit1 is 6 points and Limit2 is 4 points.) In addition, when a
margin is set at each of Limit1/2, evaluation can be performed
using the lines, taking into account the margins. Once Limit1/2 has
been set, the level direction can be fine-adjusted by the margin
setting.
Line: Limit1, Limit2
Judgment type: Upper Limit, Lower Limit
Crossover (point): 1 to 100
Margin: Limit1, 2 + Display margin line
