Usb Oscilloscopes

[M@tt 77]

Just wondered if anyone knew whether these ebay PC based USB Oscilloscopes would be useful for sensor diagnostics? ie watching signals from Crank Position Sensors/Cam Position Sensors etc? ie do their monitoring ranges cover the signals from these sensors?

Max voltage: 0---5V

 

would rule out our 12v systems at a guess?

Thats right, the CAS outputs 14v peak to peak at steady cruising (i.e. +/- 7v)

cheap enough tbf

 

wouldnt really be very good for a 205 but suppose anything newer running can systems would be ideal as they run alot of stuff via 5v
