Very useful! I just ordered a set of the 545-548 on eBay.<br><br>I was working on a homebrew computer the other day, and it turns out one of my 74574's on the data bus was completely shot. My power supply was pushing over 1.5W through the chip, and I thought it was some issues with other chips in the area and something to do with floating pins(I had built half the thing before testing, and had also never worked with some of those chips before) but the dead chip was just pushing everything it was connected to to ground. Having one of those current probes would have made it a 10 second diagnosis.

Very good and I love the current probe. I’m looking for some hp logic probes for my collection they are very expensive in the the UK. I always wondered will a logic pulse damage a gate output ?

very nice device, but cost is very prohibitive, there is another equivalent product?

Is there a modern equivalent of 547a? The original one is cost prohibitive :)
