Trigger edge:
Triggering occurs at the trigger level of the specified edge of the input signal. At this time, the current
trigger setting information (trigger edge and trigger source) is displayed in the upper right corner of the
screen, as shown in the figure below.
When the voltage of the waveform reaches a required level, then a comparator switches and send a start
signal to the time base. This enables the time base to exactly synchronize with the displayed waveform so
that it remains stable on the screen.

Operations and measurements
The device can perform math operations, automatic measurements, and cursor measurements on sampled
and displayed data.
Mathematical operations:

button to open the math operation menu. In the Math submenu, channels can perform
multiple math operations between waveforms:
•
Mathematical operations (A+B, A-
B, A×
B and A/B)
•
FFT operation
The mathematical operation and the gain value of the math channel are shown at the top of the screen as
follows.
Mathematical operation: CH1 + CH2, gain
