Hi, there
I plan to use Arduino to send the trigger signal to pulse pal input 1 to generate a pulse train.
But the issue is if I directly connected the Arduino to the oscilloscope, the trigger voltage is 5V.
But if I connected the Arduino to the pulse pal and at the same time connected to the oscilloscope, the voltage is 2V, which is not high enough and cannot trigger the pulse train. That means when connecting Arduino and pulse pal, the trigger voltage is not high enough.
Do you have any idea to deal with this? Thank you
Lu
