<mxshift>
had to figure out how to use the amscope camera
<azonenberg>
Trying to figure out what i'm looking at at the end
<azonenberg>
was this cut off the DUT?
<azonenberg>
or are these complete length leads?
<mxshift>
this was used a few times and then cut
<azonenberg>
Ok so there's normally stuff coming off the end
<azonenberg>
are they just wires? resistors like the lecroy ones?
<mxshift>
it comes with just through holes
<azonenberg>
how long?
<azonenberg>
ah ok
<azonenberg>
so you have to run wire to it
<mxshift>
yes
<azonenberg>
innnteresting
<mxshift>
folks here say please don't do this
<azonenberg>
yeah i would expect the length to be tightly controlled because every little bit between the DUT and the probe input is going to contribute to reflections
<mxshift>
At 3:42 in this training video for these probes, they go to trim the lead and knock the resistor off with the cutters
<azonenberg>
wow that is not a very good video
<azonenberg>
its super blurry half the time
<azonenberg>
also lol i see the very carefully timed cut so you don't see the resistor fly off
<azonenberg>
it looks like they delaminate a bunch of stuff with that cut
<azonenberg>
at 4:15 you can see ceramic fragments and what looks like some glue and delaminated coverlay
<azonenberg>
also the soldering iron tip he's using is humongous. looks like soldering with a tree trunk lol
<azonenberg>
or a telephone pole
<azonenberg>
also using grossly excessive volumes of solder
<Degi>
That is an official video... wow
<azonenberg>
lol yes
<azonenberg>
it looks like something you'd find on the eevblog forums
<Degi>
A bit before they mentioned to not overheat it because that might cause the resistor solder to melt and move around (also the part where they cut off a part of the resistor looks very jittery and hasty)
<azonenberg>
lol yes
<azonenberg>
they did glue down the resistors though
<azonenberg>
so melting shouldnt be a huge deal
<mxshift>
There are many reasons we have a growing pile of these
<azonenberg>
lol
<azonenberg>
Any interest in an engineering sample AKL-PT5 soonish?
<Degi>
Also the solder in wires at the tip seems weird, especially in terms of consistency... I guess you could put wires there and never desolder them and just calibrate it with that...
<azonenberg>
yeah it does seem hard to get good repeatable results with
<azonenberg>
mxshift: so you're not a fan of these tek probes?
<azonenberg>
is it the ergonomics? performance? both?
<mxshift>
I'm relaying my coworkers' experience: "these are horrible"
<mxshift>
Tedious to use. Easy to damage
<azonenberg>
Would love to hear specific complaints. especially about how other probes they like more beat them
<azonenberg>
Most differential probe tips are going to be easily damaged if you're careless
<azonenberg>
requiring you to custom cut wire is awkward
<azonenberg>
The LeCroy solder-in tips, as well as the AKL-PT5, have pre-cut wire/resistors already attached that is intended to stay part of the probe and not be replaced unless damaged (although it can be if damaged)
<azonenberg>
and you desolder it from the DUT after use
