In
today's fast-paced world, it's important to have tools that can help you work
quickly and efficiently. That's why the ZeroPlus LAP-C PC-based Logic Analyzer
is such a valuable tool - it helps you troubleshoot digital circuits so that
you can get them up and running again in no time. In this article, we'll take a
closer look at how this handy device works and what it can do for you.
LogicCube is a PC-based Logic
Analyzer that is very portable and ideal for use in the field. It
connects to any desktop or laptop PC by USB, making it easy to take with you
wherever you go. The built-in software provides all of the features you need to
troubleshoot digital circuits, and the large display makes it easy to see
what's going on.
One of the best features of the LAP-C series is the built-in FPGA (Field Programmable Gate Array). This allows users to customize the logic analyzer to their specific needs. For example, users can add custom trigger conditions or develop their own plugins for specific applications.
Another
great feature is the advanced triggering system. This allows users to create
complex trigger conditions that can be used to capture elusive bugs.
The
LAP-C series features a large color LCD display, making it easy to see the
captured data. The unit also has a built-in USB port, so it can be easily
connected to a PC for analysis. The LAP-C series offers a sample rate of up to
100 MHz, making it suitable for high-speed digital circuits.
The
LAP-C is available in a variety of configurations, including 32 channels with 2
Mb/channel and 16 channels with 32k bits of memory per channel. It is a
competent gadget in the series that comes equipped with decoding more than 120
protocols.
As
for screen upgrades, they happen quickly. It only took 5 seconds to transfer
the data to the PC, even though each of the 32 channels required 2 million
bits. If you reduce it to 256 kb/channel, the upload takes less than a second.
Specifications:
- Sample rate: Internal clock 100 to 200 MHz,
depending on model (from the manual: "Remember that the sample rate
should be at least 4 times higher than the DUT signal frequency for the
sampling to be accurate."
- External clock: 75 to 100 MHz,
depending on the model.
- Memory: 32 Kb to 2 Mb per channel,
depending on model
- # channels: 16 or 32
- Threshold voltage: settable from
-6 to 6 v with a 0.1V resolution
- Triggers: state, edge, or pattern
- Trigger sequence levels: 1
- Trigger pass counter: 65535
- Input impedance: 500 KΩ, 10 pF
- Protocol decoders: > 120 included. Some models
can trigger on protocol comm
- Powered by the host PC's USB. The
unit pulls 500 mA.
Comparison
of two LA files' waveforms as data (their environment parameters should be the
same). The program will automatically indicate the waveform discrepancies with
orange wavy lines, and the contrasting outcome will be shown in the LOG window.
Users
may specify a conditional period to check if any signal is out of the
condition, and if any is, the program will label that channel's channel in red.
Statistics: Users can examine the number of positive periods, negative periods,
and complete periods of each channel in the Statistics window.
Memory
Analyzer: Show the common memory map for the packet data that was decoded by
the standard modules. Users of EEPROM can quickly manage memory operations by
clearly understanding the read/write state of each bit address in the memory.
Bus Packet List: Using modules, the default software can decode the packet status of a variety of series protocols and display it in a packet list, which displays the enormous amount of packet data as a tree and allows engineers to examine the relationships between the packet statuses more rapidly.
With
logic analyzers, memory is everything. The LAP-C has the advantage of filtering
signals to conserve that resource. In other words, only when specific
user-defined signals are high or low are samples kept. Additionally, a delay
can be used to ensure that signals are filtered for a while after the filter
condition has been met.
I
have a really favorable view of the LAP-C overall. Though I did read the full
manual, the UI is quick, responsive, and generally straightforward. The
function keys are effectively used. Additionally, it comes with a really good
hard zip-up carrying bag, which could be the pinnacle of nerd accessories for
the fashion-conscious.
