AC coupling mode. Only the AC
portion of the signal appears on the
display. This mode is useful for
observing AC waveforms mixed with
DC components.
Inverting the waveform vertically
1. Press the Channel key.
2. Press Invert. The waveform
becomes inverted (upside
down) and the Channel
indicator in the display
shows a down arrow.
Limiting the waveform bandwidth
Bandwidth limitation puts the input signal into a
20MHz (−3dB) low-pass filter. This function is
useful for cutting off high frequency noise to see
the clear waveform shape.
1. Press the Channel key.
