Average
Every capturing of an input signal averages data on the same time
(Average)
axis and displays the waveform.
A verage
Selecting Average shows the Count on the menu. Set an average count
count
(2, 4, 8, 16, 32, 64, 128 and 256) depending on the noise condition.
(Count)
The greater the count, the greater the effect of eliminating noise in the
signal becomes, but processing takes more time.
Example of measurement when averaging is not performed
Example of measurement when averaging is performed
In the single sweep mode, averaging is
stopped after specified averaging cycles have
been performed completely.
Noise in the signal is eliminated by averaging.
Averaging restrictions
In the roll mode or long memory, Norm smpl (normal sampling) is set automatically
even if Average is selected.
Indicates normal sampling.
Sets acquisition mode to Norm Smpl.
Signal with large noise
Since a signal (sine wave of approx.
130 kHz) includes noise of over 10
MHz, the trigger coupling is set to
HF-R to stabilize triggering.
Indicates averaging operation.
Sets acquisition mode to Average.
Sets average count to 64. L is effective.
Performs averaging even when equivalent
sampling is set.
Averaging is not performed in the roll mode (short
memory with sweep time slower than 100 ms/div).
Averaging is not performed with long memory.
