2. Avg Mode
Sets the average mode to "Exponential" or "Repeat". The default average mode
is "Exponential".
 When "Exponential" is selected, the result is the exponential average of the
measurement results obtained in the past N times (N is specified in "Avg
Number").
 When "Repeat" is selected, the result is the arithmetic average of the
measurement results obtained in the past N times (N is specified in "Avg
Number").
3. Avg State
Selects whether to auto averaging the measurement results. By default, it is set
to "On".
4. TP Type
 Peak
Displays the power of the signal (with the maximum amplitude) between
the start line and stop line. The detector type is set to "Pos Peak"
automatically.
 Average
Displays the average power of signals between the start line and stop line.
The detector type is set to "Voltage Avg" automatically.
 RMS
Displays the root mean square value (expressed in W) of the voltages of
signals between the start line and stop line. The detector type is set to
"RMS Avg" automatically.
5. Start Line
Sets the left margin (in time unit) of T-Power measurement. The calculation
range for the data of T-Power measurement is from the start line to the stop line.
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.
