I'm using it this morning, 19bit AC/DC load, mostly use it in AC mode. 250V, 40A |

Well used HP case, unfortunately these boxes do not fit deep into my workplace 👍 beautiful work 👍 |

This is a very simple low-voltage differential probe I made a while ago, mostly to use at audio frequencies, so is just built with a TL052 with some 0.1% 100k resistors. I had it open today to check which op amp I used so decided to take a picture. The front-panel switch is to engage a 40 kHz 2nd-order Butterworth low-pass filter (very useful when measuring outputs of some class-D amplifiers). I measure 50+ dB CMRR in the audio band. It frees up a channel on my 2-channel scopes, so is pretty useful. jason |

Not in use now, but in progress: Power inductor checker, inspired by: http://elm-chan.org/works/lchk/report.html I designed the board and made some changes, the first test showed that some improvements are still necessary. When I have them on the way, a separate thread will follow. |
