6.3 Oscilloscope Cannot Capture Signals
Possible reasons:
●The oscilloscope input channel is not connected correctly.
●The input signal amplitude is too small or too large,exceeding the oscilloscope range.
●The trigger setting is incorrect.
Solution:
●Check whether the probe is correctly connected to the oscilloscope input channel.
●Adjust the vertical sensitivity and time base settings to ensure that the signal can be captured.
●Check whether the trigger mode is set correctly, such as selecting "rising edge" or "falling edge"
trigger.
●Confirm whether the connection between the probe and the signal source is stable and the
wiring is intact.
6.4 Signal Generator Cannot Output Signals
Possible reasons:
●The signal generator is not enabled.
●The signal generator hardware is faulty.
●The output frequency or amplitude setting is incorrect.
●The output clip interface is in the wrong hole position.
