The trigger options are somewhat poor, according to the manual.
Only types: Edge and Video. No external trigger. Holdoff only works from 100 ns.
The competition from Hantek has many more types: “Edge,Pulse,Video,Slope,Overtime,Window,Pattern,Interval,Delay,UART,LIN,CAN,SPI,IIC”.
That seems a bit old-fashioned with the Owon.
