Almost
every electronic laboratory is equipped with oscilloscope, which can provide
operation and measurement results to the engineers through 2~4 channels.
However, on the measurement of digital system, the engineers generally place a
higher demand on the channel number, other than oscilloscope.
To avoid the shortcomings of common bulky logic analyzer with complex
functional operations, Leaptronix has developed a compact and
easy-to-operate LA20 Series Logic Analyzer. This
manual has 10 reasons to help the engineers make a deeper understanding of the
logic analyzer, and also enable the designers to market their new products
quickly.
Reason
1: To make you design more easily
LA20
Series Logic Analyzer is designed in such a manner that you can identify clearly
the logic state during measurement process, and mark 0 and 1 directly on the
waveform. In addition, LA20 series has the function of Glitch.
You can visualize small glitch on the screen if glitch is detected, or
find out more information if capturing data at a higher sampling rate.
Reason 2: find out quickly your desired data in the
captured data
LA20
Series can capture over 512,000 dots separately from 32 channels, and also make
it possible to process bigger data size.
Zoom/shift
function: a special oval shift key provides visual control of zoom and shift
capture, of which up/down for adjusting zoom, and left/right for shifting the
waveform. When this key is pressed and held, the waveform will shift more
quickly, and you can shift data from one end to the other end within a few
seconds.
Reason
3: analyze parallel bus
LA20 Series allows for establishing parallel bus. The codes can be
displayed automatically provided that the channels are assigned with data
lines. Meanwhile, 16 busses can be displayed and defined, enabling you to check
the code data of parallel bus; additionally, the searching function permits to
search for complete captured data, thus simplifying greatly your
identification.
Reason
4: analyze serial bus
The serial busses, such as: I2C, SPI and UART, are extensively applied to
embedded system for communication and initialization; if the captured data is
decoded artificially, this cumbersome job will take a lot of time. LA20 Series
can help the engineers define and then decode I2C, SPI and UART busses very
easily.
Reason
5: capture events
The logic analyzer is characterized by its triggering function. Given the
discrete triggering mode, the currently available products cannot capture
accurately the data to be analyzed; LA20 Series enables the users to select
three-level continuous/discrete trigger setting, and capture data more
accurately without the trouble of triggering data; to ensure more comfortable
operation and setting for the benefit of engineers, OR Trigger, Trigger Counter
and Pulse width Trigger, etc, can help find out quickly the interest of the
engineers.
Reason 6: Auto-Store could identify quickly the problems
from software or hardware end

engineers.
Reason
7: measure mixed signal from Trigger Out
During measurement of mixed signal, synchronous test can be conducted with
the help of Trigger Out (external trigger) of logic analyzer and digital
oscilloscope, enabling monitoring and troubleshooting of mixed signal
synchronously.
Reason
8: PC Remote Control
During measurement of mixed signal, synchronous test can be conducted with
the help of Trigger Out (external trigger) of logic analyzer and digital
oscilloscope, enabling monitoring and troubleshooting of mixed signal
synchronously.
Reason
9: Probe of logic analyzer
The probe is crucial to obtain measurement results. The circuit board is
sometimes designed with test point, or welded with conducting wire to obtain
signals; LPTL 8 Channel signal capture wires’ design conform to the test
environment:
1.
The input end of every
8 channels is fitted with a probe that can be directly inserted into 2.54 mm
pin header.
2.
The probe of 1m can
facilitate the measurement of signals at different areas of the circuit board.
