4 Depending on the type of filter selected, press Upper Limit and/or Lower Limit ,
and turn the entry knob to adjust the limit.
The horizontal scale control sets the maximum value for the upper and lower
limits.
Digital filters are not available when:
• The horizontal scale is 20 ns/div or lower.
• The horizontal scale is 50 ms/div or higher.
To change the Volts/Div control sensitivity
When you need to adjust the amplitude/div setting in smaller increments, you can
change the sensitivity ofthe vertical scale control.
1 If the channel’s menu is not currently displayed, press the channel key ( [1] , [2] ,
[3] , or [4] ).
2 In the Channel menu, press Volts/Div to toggle between:
You can also toggle between coarse and fine settings by pushing the vertical scale
knob (see “To adjust the vertical scale" on page 43).
To invert a waveform
You can invert a waveform with respect to the ground level.

BPF (Band Pass Filter).
BRF (Band Reject Filter).
Coarse The verical scale knob changes the amplitude/div setting in a
1-2-5 step sequence from 2 mV/div to 10 V/div (with “1X”
probe attenuation).
Fine Also known as vernier, the vertical scale knob changes the
amplitude/div setting in small steps between the normal
(coarse scale) settings.
