DIY Logic Analyzer Probe and Pods for Siglent (and LeCroy) scopes
Old Printer:
Wish there was a version for the 1104x-E :(
Don't really want to spend the extra $900 to upgrade to the 1204 plus, though that is a beautiful screen.

if we where playing with analog signals, cross talk is much more visible, and important to avoid.
but a logic analyzer is DIGITAL, and it is alot more imune,
I tried many different signals at the same time, from 10 to 500MHz at the fastest rise times my generators can create,
and I am not able to detect any cross talk.
so it is really noth worth the trouble and hard work, to use coax, it is a nightmare to solder, and much more stiff..
just take what ever thinn wires you got, and twist them.. done deal..
IMPORTANT : cut all wires to exactly the SAME length, look at the PCB's i made, all tracks are exactly the same length, and as short as possible,
and spaced as much as possible, and made so their individual capacity, inductance, cross talk, is as little as possible, and as even channel to channel as possible,
when running tests at 500MHz with 1nS rise time, it is barely visible the different response i get on the scope,
and some of it could just as well be inside the scope, it is that little.

It is supposed to have MSO with a $109 firmware option, which I believe is hackable, and a $329 16 Channel Logic Probe set of leads. Maybe it does not have the active components built into the scope as the 1204+ does??

I just checked its specs, cant even find the LA connector, on that scope

There is S_bus connector next to USB.. It uses external device that does acquisition, that is not passive and you have to buy it... It works but is not as powerful as 2000X+ with fully integrated MSO.
If MSO is really needed, instead of buying SLA1016 for 350 €, I would put that money forward to upgrade to SDS2000X+. And if you sell SDS1104X-E you recoup some money too.
SDS2000X+ is whole different level..... If you can afford it, that is clear winner...
