operations and advanced operations. 
 

 

REF

: press this key to enable the reference waveform function. You can 

compare the waveform actually measured with the reference waveform. 

 

 

Decode1

Decode2

: press any key to open the corresponding decoding 

function menu.   
MSO4000/DS4000 supports parallel decoding and various protocol decodings

MENU

: press this key to open the horizontal control menu. You can turn on or 

off the delayed sweep, switch between different horizontal time base modes,

: horizontal scale knob. 

Turn the knob to modify the horizontal time base. During the modification, the 
waveforms displayed are expanded or compressed horizontally; the horizontal 
time base message (as shown in the figure below) at the upper-left side of the 
screen changes accordingly. Pressing down the knob can quickly turn on or off
