USB 2 Channel PC Oscilloscope Review

Average Reviews:

(More customer reviews)I have really started to like my scope. At first it took a little getting used to since the controls are a bit different from a hardware scope -- but now it is my scope of choice on the bench except where I need the wide bandwidth of an analog scope. The hardware is supurb -- it is accurate and the triggering is excellent. The best feature, of course, is its ability to show what happened BEFORE THE TRIGGER which is great for catching the glitches that caused the trigger event.
The spectrum analyzer is OK once you understand that there is not low pass filter so that signals that are above the high frequency cutoff alias into the inband display. It could have log displays etc, but for the dollar it's a great value.
The transient recorder looks good and is a unique feature that I haven't had occasion to try yet.
The scope installed quickly and ran the first time on my windows XP and VISTA machines. The two probes that are supplied are great quality and very similar to the TEK/HP probes we are all used to.
My only criticism is that while the software user interface is quite usable, it's a bit clumsy and was probably written some time ago and never updated to act like more current interfaces. The online documentation is a bit weak and could use some improvement and the hard copy is very basic. But, as I said, the scope is quite functional after you get used to the interface.
While it isn't quite as good as a $5000 TEK digital scope it sure gives plenty of bang for the buck.
I'd buy it again in a minute.

Zeroplus LAP-C 16128 Logic Analyzer Logic Cube Review

Average Reviews:

(More customer reviews)I've tried several of the off-brand USB logic analyzers and they are mostly junk. I had almost given up and gone back to the old green-screen tek, but the LAP-C is really a breeze to use and very powerful for the price.
ZeroPlus has really done a great job with both the hardware and the software. Easy plug (& install) & play setup, and after that - it just works. For a first test, just tap a wire onto the VDD pin on the connector and try capturing rising/falling edges. Once you're convinced it's alive, hook it up to your full circuit and fire away. I also like the physical trigger button because sometimes the last thing you want to do is go grab the mouse while trying to hold a wire onto testpoint x.
But one button alone wouldn't convince me. We threw all sorts of conditions at the LAP and it always got beautiful captures. The software is well constructed with almost too many options - RTM for sure here - and the protocol analyzers are exceptional. The downside is that each protocol is sold seperately, sometimes for more than the cost of the device!
But if your use does not require exotic protocols, this device will provide plenty of features and deep enough memory (and triggering options) to capture quite a bit of data in a very reliable manner. If you're in the market for a low-cost logic analyzer, I recommend the LAP-C.
