I am using a PicoScope 6403, and I am very interested on using the external trigger input as a trigger for the scope. I have tried using PicoScope6 software with following trigger settings:
- Simple Edge
- Source: AuxIO
- Threshold: 500mV
But I cannot get the trigger working with any signal applied in this input.
Please, could you give me some information about using this external trigger?

ziko, I am using a square wave signal with several amplitudes (e.g 1V peak-peak, between 0V and 1V) but the scope is not triggering. If I use this signal in any of the common channels (channelA..channelD) and I configure the trigger accordingly, the trigger works. But not in AuxIO channel.
Hi, i also have this problem. I can trig on any órdinary input channel but not on auxio, also, the marker for trigger point does not show. Didi you have a solution? I have a picoscope 6400.
The trigger signal is 5V hi and going to 0V is my trigging event. I use single falling edge trigger at 4V when working fine on ordinary channels. Tested 0.1 to 4.9 V on auxio but traces just updates at the set trigger point.
The Aux input for the 6000 series has an input impedance of 50 Ω. You will need to look at the output impedence of the signal generator you are using and, if not 50 Ω, match the impedance or adjust the trigger levels accordingly.
