So, if you detach USB connector from the "dongle" it will absorb current from input digital signal lines trying to supply the LA ... ;) Apart that its worth the money. To be honest Sigrok based Pulseview is a very minimal LA application, it lacks some important features like trigger on serial content, that means a lot for serious debugging. Current Saleae Logic versione does it and I'm afraid that once you've tried it (Logic) you'll never go back (Pulseview), like all the all hobbyists in this forum :D |

That's their cheapest. |
