Averaging

Trace Averaging helps to smooth a trace to reduce the effects of random noise

on a measurement. The FieldFox computes each data point based on the

average of the same data point over several consecutive sweeps.

Average Count determines the number of sweeps to average; the higher the

average count, the greater the amount of noise reduction.

An average counter is shown in the left edge of the screen as Avg N. This

shows the number of previous sweeps that have been averaged together to

form the current trace. When the counter reaches the specified count, then a

'running average' of the last N sweeps is displayed. Average Count = 1 means

there is NO averaging.

Automatically adjusts the Y-axis to comfortably fit the

Minimum and Maximum amplitude of the trace on the screen.

2. Set Scale, acquisition, and Reference Position:

Manually enter a scale per division to view specific

areas of the trace

Enter a negative value by pressing Run/Hold (+/-) either

before or after typing a value

Manually set the position of the reference line.

Values must be between 0 (TOP line) and 10 (BOTTOM

3. Set Top and Bottom graticule values. The scale per division is

to set the value of the Top graticule.

to set the value of the Bottom graticule.

— Enter a negative value by pressing Run/Hold (+/-) either

before or after typing a value.

Manually set the value of the reference line.
