Detect glitches and eliminate the possibility of
aliasing.
Reduce random or uncorrelated noise in signal
display. The number of averages is selectable.

Normal: For the oscilloscope model with the bandwidth of 100MHz, the maximum sample rate is
1GS/s. For time base with insufficient sample rate, you may use the Sine Interpolati on Algorithm to
interpolate points between sampled points to produce a complete waveform record (4K by
default).

Peak Detect:

Detect:
Detect: Use this mode to detect glitches within 10ns and to limit the possibility of aliasing.
This mode is valid at the SEC/DIV setting of 4 µ s/div or slower. Once you set the SEC/DIV setting
to 4 µ s/div or faster, the acquisition mode will change to Normal because the sample rate is fast
enough that Peak Detect is unnecessary . The oscilloscope does not display a message to tell you
that the mode has been changed to Normal.

Average: Use this mode to reduce random or uncorrelated noise in the signal to be displayed.
Acquire data in Normal mode and then average a great number of waveforms. Choose the
number of acquisitions (4, 16, 64 or 128) to average for the waveform.

Stop the acquisition (press the RUN/STOP button) to freeze the display. I n either mode, the

can get a resolution of 40ps , i.e.
25GSa/s sample rate, which is much higher than that obtained in real-time acquisition.
