* Question
| What are the external trigger signal input sections? |
* Answer
| The external trigger signal input is used to access the external trigger source.In most cases, the oscilloscope is used in the internal trigger mode, that is, the measured signal is used as the synchronous trigger source.However, when the measured signal waveform cannot be used as the synchronous trigger source, the external trigger synchronization signal needs to be selected.However, the amplitude should not be too large. If it is too large, it will damage the external trigger signal channel.When an external trigger signal is required, you need to check the oscilloscope’s instructions to confirm the voltage amplitude of the external trigger signal channel |
