DS4000 provides independent vertical control systems for the four analog input
channels.
 CH1, CH2, CH3, CH4: analog input channels. The four channels are marked
by different colors which are also used to mark both the corresponding
waveforms on the screen and the channel input connectors. Press any key to
open the corresponding channel menu and press again to turn off the channel.
AC: illuminated when AC channel coupling is enabled.
50: illuminated when the channel input impedance is 50Ω.
BW: illuminated when bandwidth limit is enabled.
 MATH: press this key to open the math operation menu under which (add,
subtract, multiply, divide) operations, FFT operation, logic operation and
advanced operation are provided.
 REF: press this key to enable the reference waveform function to compare the
waveform actually tested with the reference waveform to decide circuit failures.
 VERTICAL POSITION: vertical position knobs. During the modification,
the position label at the lower left corner of the screen would change accordingly.
Turn clockwise to increase the position and counterclockwise to decrease. Press
down the knob to quickly reset the vertical position.
 VERTICAL SCALE: vertical scale knobs. During the modification, the scale
