Measurement Interface:
Figure 2-21 TOI Measurement Interface
Measurement Results: Base Lower, Base Upper, TOI (3rd Order Lower), TOI
(3rd Order Upper), the frequency and amplitude of each kind of signal, the
amplitude difference between each kind of signal and the base lower as well as the
intercepts of the base lower and base upper.
Wherein, the intercept of 3rd Order Lower = (Base Lower Power - 3rd Order Lower
Power)/2 + Base Lower Power; the intercept of 3rd Order Upper = (Base Upper
Power - 3rd Order Upper Power)/2 + Base Upper Power.
Measurement Parameters: average number, average mode and span.
1. Avg Num
Specify the number of averages used when calculating the measurement
result and the default is “Off”. You can use the numeric keys, knob or direction
keys to modify this parameter.
