Intronix LogicPort questions...

[alank2]

Hi Everyone,

I'm thinking about ordering one of these, but have a few questions.

#1 - Is the case easily opened?  Some plastic cases are ultrasonically sealed which I can't stand, but are there screws on the bottom so you can open it?  I noticed a picture of the pcb showed a header where you could get the trigger output feature that they charge extra to install and while it isn't a huge feature I want to necessarily pay for, I'd like to know I could use a trigger output if I had to in a situation.

#2 - Are the wires on the probe simply color coded with a color ending, or do they actually have a printed label on them identifying which wire is which as well?

#3 - Is there any place that sells these at a discount?  They have not been receptive to me asking for one that is for sure.

Thanks,

Alan

I have one.  The software is rock solid, and the triggering is quite extensive. The 2k memory depth is quite small, especially for slow moving signals, you have to finess the trigger to get it to capture just right. That's the most annoying thing about it, actually. There is compression and it does help a little.  Other people on the forums have said how they like to just use a logic analyzer with a large memory depth and just let it capture everything then scroll through it.  With the LogicPort you  don't have that luxury and really must spend more time to think through your trigger setup.

The case opens easily with 5 screws. Not a problem. The 5th screw hole has a drop of Loctite, as a sort of warranty seal I guess.  Inside, the design is simple, but good, and there is only minimal input protection on the probe leads, but they are 40VDC tolerant and I've never blown it up.

The probes are color coded wires black to violet for D0-D8, and grouped into 4 groups with color coded plugs, WHITE, BLUE, YELLOW, GREEN, for each of the 4 data groups. GROUND is the grey wire with black plugs.  The GND on the probes is also USB GND and Chassis GND, so there is no isolation if you need that.  There is no labeling on the probe ends, there is only colors. But the software is also color coded to match, so it's never been a problem. Plus I know the resistor table by memory, and this only helps reinforce that memory

The plugs are .025" square post compatible, and they plug into mini-grabbers or headers/test points on your board.  The standard set of grabbers is all black, no color coded grabbers. 

I don't know of any discount sales.
