Use the display menu to perform these tasks.
Press the main-menu button Style. Use the side menu to select from these
display styles:
H Press Vectors to select vector display style. The oscilloscope draws a vector
between each pair of waveform points.
H Press Dots to select dot display mode. The oscilloscope displays only the
waveform points.
H Press Vector Accumulate or Dot Accumulate to set the display to accumulate
dots. Use the General Purpose Knob to adjust the time limit (from 500 ms to
10 s in 250 ms increments or R). The display accumulates dots until it
reaches the time limit. It then clears the waveform and starts over. Dot
Accumulate mode shows the latest acquired waveform in dot format, while
Vector Accumulate mode shows it in vector format.
Press the main-menu button Intensity. Use the side menu to select from the
following menu items:
H Press Overall to adjust the intensity of the screen as a whole. Use the
General Purpose Knob to vary screen intensity.
H Toggle Text/Grat to switch the text and graticule between bright and dim.
H Toggle Waveform to switch the waveform between bright and dim.
H Press Contrast to adjust the contrast between the bright and dim settings. Use
the General Purpose Knob to vary the contrast level from 100% to 250%.
(When you set contrast to 200%, the dim setting is half as bright as the
bright setting.)
