Term interpretation
Trigger:
With this oscilloscope there are three types of trigger modes: automatic,
normal and single.
Automatic trigger mode:
The oscilloscope can detect in this mode the curve without a selected trigger
condition.
During a particular waiting time a Force-Trigger is done when no
trigger condition occurs. If an invalid trigger condition is used, the
oscilloscope cannot keep the curve in phase.
Normal trigger mode:
In this mode, the oscilloscope cannot detect the curve before it is triggered.
Without trigger the oscilloscope displays the original curve without new
curves are recorded.
Single mode:
In this mode, the oscilloscope detects a trigger and captures the curve
whenever the operator presses the RUN / STOP (Run / Stop) button.
Sensitivity:
Trigger circuit with delay line to avoid effects due to noise and to obtain a
stable trigger. The delay line is adjustable between 0.2div and 1.0div. This
means that when set to 1.0div the trigger circuit does not respond to a signal
with a peak-to-peak valu
e ≤1.0div, eliminating the effects of interference.
