| Differential probe for offline PFC'd PSU |
| << < (4/7) > >> |
| H.O:
Here's the DP750-100, set to 50:1, measuring a 3V 125kbit/s CAN-bus signal (in a fairly "clean" environment). |

--- Quote ---That solves nothing. Do it right before you get yourself killed. --- End quote --- Thanks, but it solves the fact that i am skint after spending over £1k getting this project going......i will just be careful not to touch the scope ground whilst the scope is powered. A 200W isol txfmr to power the scope with is the cheapest way. And the local burglars are less likely to steel a 200W isol txfmr. ...no earth to the scope. Being very careful not to touch as discussed. (I will be using my soldering iron, to inscribe "This is stolen if youre not xxxxx" into the plastic on my Tenma 72-8225 40MHz scope) |

Dave's Eevblog HVP70 has better bandwidth and is cheaper is it not? I didn't check all of the specs but your linked pico appears to be 25Mhz vs 70Mhz for the HVP70. The other question, I suppose, is what does $450 in AUS vs your currency once you have it in your hands. Appears to be in stock currently. What am I missing here...? https://www.eevblog.com/product/hvp70/ |

I bought a Micsig diff probe. I'm too young to die. |

I would buy the DP10007. It's a cheap and idiot proof solution to the problem. |
