 reference waveform of this unit does not support other 

operations such as expansion or measurement. The 

reference waveform is useful for a single-channel 

oscilloscope. For example, when you want to compare 

the driving waveforms of two Mos tubes, you can measure 

the waveform of one Mos tube first, then lock the waveform 

on the screen, and then move the probe to measure 

the other. Mos tube, so two driving waveforms can be 

displayed on the screen at the same time for easy 

comparison. In the 

“running”

 state, click the

 “REF”

 button 

to latch the current waveform. Click the button again 

to delete the latched reference waveform from the screen.
