• Average
Accesses the Average submenu.
• Average
Enables or disables the Averaging function.
• Avg Count
Sets the filter length and average count values
to be Auto or Manual.
The power sensor automatically sets the number
of readings averaged together to satisfy most
power measurements averaging requirements.
The number of averaged readings depends on
the resolution and the power level settings the
power sensor is currently using.
• Step Detect
Enables or disables step detection. In AUTO
filter mode, the average of the last four values
entered into the filter is compared to the entire
filter average. If the difference between the two
averages is greater than 12.5%, the digital filter
is cleared. The filter will then start storing new
measurement data. This feature shortens the
filter time required when the input power
changes substantially. Note that the result
appears to settle faster, although true settling to
the final value is unaffected.
• Meas Interval
Sets the interval time between two measure-
ments.
Preset
Key access: [MODE] > {Power Meter} > {Preset}
Sets the Power Meter softkey menu options to the
preset conditions. For example, the Upper and
Lower Limits are set to their preset limit values.
