Averaging and trigger mode
(1) Trigger mode: SINGLE
1. After the
START
key was pressed, data are captured whenever the trigger
conditions are fulfilled, averaging is carried out, and then the waveform is
displayed.
Collected waveform data is averaged with the FFT time axis waveform and
FFT processing is performed. FFT processing is performed on the frequency
axis and the calculated result is averaged.
2. Trigger occurs when the trigger conditions are fulfilled again.
3. When the specified number of data has been captured, measurement stops
automatically. If the measurement was stopped prematurely with the
STOP
key, the averaging result up to that point is displayed.
(2) Trigger mode: REPEAT
1. After the
START
key was pressed, data are captured whenever the trigger
conditions are fulfilled, and averaging is carried out until the specified
averaging count. The averaging result is shown on the display.
2. Trigger occurs when the trigger conditions are fulfilled again. The waveform
data is cleared and the trigger occurs when the trigger conditions are fulfilled
again
3. When the specified averaging count is reached, data up to that point are
discarded, and new data are captured for averaging. If the measurement was
stopped prematurely with the
STOP
key, the averaging result up to that point
is displayed.
