Here's my board all finished up. 8) What do you guys think? Here are some of the measured rise times. The first image is with 1 loop and the second image is 8 loops. I noticed if I measure at the input to the loop, I get a voltage spike. This is most noticeable with the 8 turn loop. Can someone check the Siglent board to see if the same thing happens? |

Hi, In the LTspice simulation that I showed a few messages ago, you get the voltage spike if you connect the voltage probe to the top end of the coil. Try connecting the voltage probe to the other end of the coil. Regards, Jay_Diddy_B |

I was just looking for a de-skew board since I'm not paying $700 for a PCB with a 555 timer - this design looks nice. |

@Ribster Did you ever get a chance to test out your fixture? I've been really interested in making a fixture for my Tek TCP312 and lecroy CP030 probes. Your design looks really nice. If you haven't had a chance to test it and are willing to open up the design, I for sure will be willing to give it a go! Thanks! Brak |

Hey there! My design works and i’ve made the prototypes. A forum member here contacted me and i sold him my prototype. If you’re interested i’ll produce a batch of 20 more and sell them on a tindie store. Is there interest in buying a unit? You can always hit me up at shop (at) ashlabs.be I’ll send some scope plots or the unit with the GaN mosfet. Which i will produce 20 of. Kind regards |
