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 Interpolation Algorithm to
interpolate points between sampled points to produce a complete waveform record (4K by
default).
Peak Detect: Use this mode to detect glitches within 10ns and to limit the possibility of aliasing.
This mode is valid at the TIME/DIV setting of 4µs/div or slower. Once you set the TIME/DIV setting
to 4µs/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.
Stopping the Acquisition: When you are running the acquisition, the waveform display is live.
Stop the acquisition (press the RUN/STOP button) to freeze the display. In either mode, the
