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 averaging the measurement results. By default, it is set to
"On".
4. Max Hold
Enables or disables max hold. By default, it is "Off".
 When Max Hold is enabled, each measurement result is compared with the
previous result, and then display whichever is the maximum.
 When Max Hold is disabled, the current measurement result is displayed.
 Max Hold and average measurement mode are mutually exclusive. When
Max Hold is enabled, the average measurement mode will be automatically
disabled.
5. OBW Span
Sets the frequency range of integral calculation. The span is consistent with that
of the spectrum analyzer. It is the frequency range of sweep. After it is set, the
span of the spectrum analyzer will also be changed. 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.
