content: After seeing this in one of Signal Path Blog's videos, I have been looking for this, but they seem expensive ($64).Has anyone found a cheaper alternative or made their own?

content: Won't really help you, but one of the reasons I really like my HP 1165A probes is that they come with accessories like that. It's really weird that the probes that come standard even with pretty pricey scopes seem more suited to poking around a tube radio than connecting to a modern SMD circuit.

content: http://www.probemaster.com/product_info.php?cPath=1_9&products_id=238you can buy the buy the wire wrap ground lead/ probe tip adapter seperately. Together under$8.00 + shipping.

content: The tip end (pin and barrel diameter) of a scope probe will vary from vendor to vendor. So, you can't just buy an adapter easily, more often than not it won't fit unless specifically made for the probe you have.My scope probes came with an adapter that slips onto the probe end and provides a BNC male slip. Just purchase a BNC female and solder your own 2 wires to it (I prefer thin gauge silicone insulated test leads) and terminate as required (female pins + heatshrink etc). It's several connectors, but not a big deal since with flying leads you aren't looking to probe high frequency signals and worry too much about displayed signal integrity.Some scope probes come with the 2 wire adapter - but it's not as common.cheers,george.

content: Here you go, made one this morning. <$2 for the BNC female. A couple of short lengths of silicone test lead, bit of heatshrink and all done. Pics below showing the steps and finished result.This of course presuming your probes came with the probe to male BNC adapter (as mine did). The adapter is the middle item in the first picture.cheers,george.

content: Or you could skip the probe and go directly from BNC to 0.025" sockets.http://www.probemaster.com/product_info.php?cPath=1_39&products_id=308!!! Wow, why is that $95?What I'd really like are some small probes, less than 3" long, with no more than 2 ft. of cable to the BNC. I get tired of fighting with meter long (or longer) cables and 6 inch probes in my small work area.

content: it's expensive because it has the compensation box at the BNC end, 250 MHz/15pF and 10x attenuation. Does not sound like ordinary RG58 cable.Edit: maybe half the price would have been a little friendlier

content: Quote from: Neganur on March 08, 2015, 04:23:21 pmOf course the real point is... does anyone think they can actually use that 250MHz probe 'bandwidth' to measure anything approaching 250MHz with flying leads and test clips???cheers,george.

content: Quote from: cyr on March 06, 2015, 12:23:36 pmOMG so true. My HP1741 came with very slim probes, unfortunately also quite fragile, they are long gone to Silicon Heaven.Soldering irons are also too big. Too long, too thick.But then, I guess the probes are like the headphones that come with any pricy portable audio thingy. Back in my salad days I spent soooo much money on almost every MiniDisc recorder that came along and they always came with earbuds that sounded horrible.I ended up buying many full-size headphones before it was fashionable to walk down the street with Beats on your head.
