points in a number of successive sweeps resulting in trace
"smoothing". The number of sweeps (average number) is
changeable when setting Average (Off). Increasing the average
number will further smooth the trace. pressing BW > Avg Type
to select the type of averaging.
To restart averaging:
• Enter a new average number
• Change any related parameter (e.g., Center Frequency)
When in sweep single, the specified number of averages is
taken, then the sweep stops and an average trace displayed.
When in continuous sweep mode, the specified number of
averages is taken, then the averaging continues with each
new sweep averaged in with a weight of
old average reduced by multiplying it by
AverageNumber
To turn averaging off, press Average Number (Off).
Key access: Trace/Det > More > Average Number On/Off
measures the average value of the amplitude
across each trace interval (bucket). When
Average is selected, "Avg" appears on the left
corner.
Sample detection is used primarily to display
noise or noise- like signals. It should not be used
to measure the accurate amplitude of non
noise- like signals. In sample mode, the
instantaneous signal value of the present
display point is placed in memory. When Sample
detection is selected, "Samp" appears in the
upper- left corner of the display.
Selects the maximum and minimum video signal
values alternately. When selecting Normal
detection, "Norm" appears in the upper- left
corner.
