6.6 Run/stop
In the running state, click the "Run/Stop" button to stop the oscilloscope. After
stopping, the oscilloscope no longer performs sampling, and the user can observe the
last sampling data retained in the memory. Click the "Run/Stop" button in stop mode
to make the oscilloscope enter the running state.
6.7 50%
The function of 50% in the oscilloscope is to return the waveform to the middle,
including vertical offset, trigger position, and trigger level.
Operation method: Click the "xKey" button and select "50%".
6.8 Single
Single trigger means that after pressing the button, the oscilloscope samples a
frame of waveform and then stops. That is, only one frame of waveform is acquired
per click. It is important to note that there must be a trigger for this sampling. If there
is no trigger, the oscilloscope displays “wait” in the upper left corner of the
oscilloscope. This sampling is not completed until there is a waveform trigger.
Operation method: Click the "xKey" button and select "Single".
6.9 Reference waveform
The reference waveform is that the waveform of the previous frame is latched on
the screen for display.
The reference waveform is useful for a single-channel oscilloscope. For example,
when you want to compare the driving waveforms of two Mos-FETs, you can
measure the waveform of one of the Mos-FET first, then latch the waveform on the
screen, and then move the probe to measure Another Mos-FET, so that two driving
waveforms can be displayed on the screen at the same time for easy comparison.
Operation method: Click the "xKey" button and select "REF"
