Table 2-29 Average Number of T-Power Measurement
Parameter Description
Default 10
Range 1 to 1000
Unit N/A
Knob Step 1
Direction Key Step 1
2. Avg Mode
Set the average operation mode to “Exp” or “Repeat” and the default is “Exp”.
 When “Exp” is selected, the result is the exponential average of the
current N (N is specified in “Avg Num”) measurement results.
 When “Repeat” is selected, the result is the arithmetic average of the
current N (N is specified in “Avg Num”) measurement results.
3. TP Type
 Peak
Display 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
Display the average power of signals between the start line and stop line.
The detector type is set to “Voltage Avg” automatically.
 RMS
Display the mean square root (in power unit) of the voltages of signals
between the start line and stop line. The detector type is set to “RMS
Avg” automatically.
4. Start Line
Set the left margin (in time unit) of T-Power measurement. The data
calculated under this measurement is between the start line and stop line.
You can use the numeric keys, knob or direction keys to modify this
parameter.
