Averaging

Averaging helps to reduce the effects of random noise on a measurement. The
more measurements that are averaged, the greater the amount of noise
reduction. Averaging is allowed for all pulse measurements.
Averaging is performed in the USB Power Sensor before the data is sent to the
FieldFox.

— Scale Manually enter a scale per d ivision to view specific areas of
the trace.
— Ref Level Manually set the value of the reference line. Enter a
negative value by pressing Run/Hold (+/-) either before or after
typing a value.
— Ref Pos Manually set the position of the reference line. Values must
be between 0 (TOP line) and 10 (BOTTOM line).
— Offset ON Enable Offset. When only trace 1 is visible,
appears to the left of the trace.
— Offset Val Enter a value by which all amplitude values will be offset.
This can have the effect of virtually removing a component from the
measurement path. A positive value compensates for a component
with loss. A negative value compensates for a component with gain.
Offset values are limited to +/- 100 dB.
