Impedance matching gives you the most accurate measurements because
reflections are minimized along the signal path.

To specify bandwidth limiting
Each analog input channel has a 40 MHz BW Limit option that lets you disable or
enable a bandwidth limit (using a digital filter). Limiting the channel bandwidth
lets you remove unwanted high frequency noise from the waveform and increase
the number of bits of vertical resolution.
1 Open the Channel dialog box by selecting the Channel badge or by choosing
Sources > Channel N... from the main menu.
2 In the Channel dialog box, select the 40 MHz BW Limit option.
Note that there is also a Global BW Limit selection in the Acquire dialog box that
affects all analog input channels. See "Selecting a Global Bandwidth Limit and
Vertical Resolution" on page 171. When the channel bandwidth limit and the
global bandwidth limit are both selected, the lower bandwidth limit is applied.
To change the vertical scale knob's coarse/fine adjustment setting
You can do one of these things:
• Push the vertical scale knob to toggle between fine and coarse adjustment of
the vertical scale.
• Select the Fine option in the waveform's settings dialog box (that you can open
by selecting the waveform badge or by choosing Sources > (waveform)... from the
main menu).
When Fine adjustment is selected, you can change the channel's vertical sensitivity
in smaller increments. The channel sensitivity remains fully calibrated when Fine is
on.
The vertical scale value is displayed in the waveform badge at the top of the
display.
When Fine is turned off, adjusting the vertical scale goes in a 1-2-5 step sequence.
