Setting the oscilloscope bandwidth
Use this procedure to set the oscilloscope bandwidth. Bandwidth is the maximum
frequency that an oscilloscope can accurately display and measure. The
oscilloscope gradually attenuates (reduces) the signal level of frequencies that are
higher than the bandwidth. This means that although you can display signals that
are above the bandwidth limit, their amplitude values and other characteristics are
not guaranteed to be accurate.
1. Push the Vertical Menu button for the channel input that you want to set.
2. Push the Bandwidth side-menu button.
3. Use the Multipurpose knob to select and click the bandwidth setting.
■
Full sets the bandwidth to the maximum bandwidth of which the oscilloscope
is capable.
■
20 MHz sets the bandwidth to 20 MHz.
■
Other bandwidth choices may be shown on the menu depending on the
connected probe.
