Front Panel Function Overview
VERTICAL
CH1, CH2: analog input channels. The 2
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.
MATH: press this key to open the math operation menu. You can perform addition,
subtraction, multiplication, division, FFT, digital filter, logic operations and advanced
operations.
REF: press this key to enable the reference waveform function to compare the
waveform actually measured with the reference waveform.
VERTICAL POSITION: modify the vertical position of the current channel
waveform. Turn clockwise to increase the position and turn counterclockwise to
decrease. During the modification, the waveform would move up and down and the
position message (e.g. ) at the lower-left corner of the screen would
change accordingly. Press down this knob to quickly reset the vertical position to
zero.
VERTICAL SCALE: modify the vertical scale of the current channel. Turn
clockwise to decrease the scale and turn counterclockwise to increase. During the
modification, the display amplitude of the waveform would enlarge or reduce but the
actual amplitude remains unchanged. The scale information (e.g.
) at
the lower side of the screen would change accordingly. Press down this knob to
quickly switch the vertical scale adjustment modes between "Coarse" and "Fine".
