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 under which add, subtract,
multiply, divide, FFT, logic and advanced operations are provided.
REF: press this key to enable the reference waveform function to compare the
waveform actually tested 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”.
Decode1, Decode2: decoding function keys. Press the corresponding key to open
the decoding function menu. MSO2000A/DS2000A support parallel decoding and
protocol decodings.
