Third- order I ntercept ( TOI )
Measurement I nterface:
Figure 2-12 TOI Measurement I nterface
Measurement Results:
Base Lower, Base Upper, 3rd Order Lower, 3rd Order Upper, frequency and amplitude
of the above four signals, the amplitude difference between each signal and the base
lower signal, as well as the 3rd order intercept point (I ntercept) of the base lower
signal and base upper signal.
3rd order lower intercept point = (power of base lower signal - power of 3rd order
lower signal) + power of base lower signal; 3rd order upper intercept point = (power
of base upper signal - power of 3rd order upper signal)/ 2 + power of base upper
signal.
Measurement Parameters:
average count, average mode, auto average, and
span.
1. Avg Number
Specif ies the number of times for averaging the measurement results. You can
use the numeric keys, the knob, or arrow keys to modify this parameter; you can
also use the touch screen to modify the parameter.
