To turn waveforms on or off (channel, math, or reference)
Pressing the channel ([1], [2], [3], and [4]), [Math], and [Ref] front panel
keys have the following effect:
• If the waveform is off, the waveform is turned on and its menu is
displayed.
• If the waveform is on and its menu is not displayed, its menu will be
displayed.
• If the waveform is on and its menu is displayed, the waveform is
turned off and its menu goes away.
To adjust the vertical scale
When an input channel waveform is on:
• Turn its vertical scale knob to change the amplitude per division
setting.
The amplitude/div setting changes in a 1-2- 5 step sequence from
2 mV/div to 10 V/div (with “1X” probe attenuation).
Either ground or the center of the screen is used as a reference,
depending on the “Expand Reference” preference setting (see “To select
the vertical scale reference level” on page 142). The “center of screen”
reference is not available for math function or reference waveforms.
• Push its vertical scale knob to toggle between vernier (fine scale)
adjustment and normal adjustment.
With vernier adjustment, the amplitude/div setting changes in small
steps between the normal (coarse scale) settings.
The Volts/Div item in a channel’s menu also toggles between vernier and
normal adjustment (see “To change the Volts/Div control sensitivity” on
page 51).
Vernier adjustment is not available for math function or reference
waveforms.
The amplitude/div setting is displayed in the status bar at the bottom of
the screen.
