1.5 Special Functions and Patents Introduction
1.5.1 Bus Wizard
With the intelligent classification function of Smart+ software, users can do the Bus decoding settings conveniently and
quickly.
1.5.2 Auto Run(only for D Series)
The Smart+ software can auto-scan the signal and decide the best sampling frequency for capturing, so as to make full
use of the best measurement time length of LA. Users no need to select the sampling frequency by hand.
1.5.3 Image Encode (Patent pending)
CMOS: By the Image Encode function, users can restore the video digital signal that captured by the Smart+ to
pictures.
7-segment Display: After capture the signal of 7-segment display, users can quickly check its display status by the
Image Encode function.
LCD Display(1602/12864): By the Image Encode function, users can clearly see the complicated character code table,
and better handle the LCD display status.
1.5.4 Real-time Monitoring of Level/Frequency
The Real-time Monitoring of Level/Frequency function can help engineers to monitor the signal frequency and level
status, so the Logic Analyzer is not just a Logic Analyzer, it can be frequency counter and logic pen.
1.5.5 Multi-level Hardware Trigger (only for D Series)
With the 256-level hardware trigger function, users can freely set the hardware trigger for the serial signal. According
to the signal change and along with LAP-D multi-level trigger function, this function can set hardware trigger for many
serial signals, so more waveform can be captured.
1.5.6 Patents Introduction
·Data Compression (Patent US7.392,434B2)
Zeroplus Logic Analyzer owns the patent technology of waveform compression. This technology can instantly
compress the signal without damaged, so the memory can store more data with higher resolution. The compression rate
can reach up to 255, that means if the memory is 128K, then as much as 32Mbits(128K*255) data can be captured in
each channel. The compression rate changes in accordance with the data content.
·Waveform Data Display (Patent Taiwan I267646)
Zeroplus Logic Analyzer can display the waveform time. Users can decide whether to display the time of waveform
width(between two rising edges or falling edges) or not in the waveform display window. There are three modes:
Sampling Site Display, Time Display, Frequency Display.
·Filter Delay (Patent Taiwan I271532)
Zeroplus Logic Analyzer owns the patent technology of waveform signal filter delay. Filter delay is to prolong or
shorten the filtering effect. In other words, it can convert the set area of filter to the reverse area of filter, or shorten/
prolong the filter area, or shorten/prolong the filter reverse area.
·Data Contrast, Bus Packet List, Memory Analyzer (Patent Taiwan I224195)
Data Contrast:
Users can contrast the waveforms of two LA files (their environment parameters shall be the same); the software will
mark their differences with orange wavy line, and display the contrast result in the Log window.
Smart+ User’s Manual V1.04.04
16 FM07I4A
Bus Packet List:
The Smart+ software can display the packet status of various protocol analyzer through the bus decoding module. Users
can use the Bus Packet List function to display huge packet data in a list, with which analyzing the relation between
each packet becomes much easy.
Memory Analyzer:
Display the packet data that analyzed by the Smart+ bus decoding module in the memory map way which is common in
memory. Take the EEPROM as an example, users can understand the read/write status of each address in the memory.
Volatile Memory Access (Patent Taiwan M398147)
It can increase the memory size and transmission speed effectively.

2.3 Tips and Advice
1. During testing, make sure that the internal sampling frequency of LA be at least four times higher than the frequency
of device under test.
2. If the connector of testing cable does not work well with the pins of device under test, try to use the supplied probe.
Fig. 2-1: Probe Supplied by Zeroplus
3. How to use the probe:
Fig. 2-2
Fig. 2-3
Step 1: Insert the loose end of the
cable into the connect pin of probe.
(Fig. 2-2).
Step 2: Compress the probe as shown
to reveal two metal prongs. Insert the
metal prongs into the metal connector
of device under test and release to let
them to grip the metal connector.
(Fig. 2-3).
4. If the internet is available, the Logic Analyzer will connect with the Zeroplus Server automatically and search for
update.
5. Unwanted signals can be filtered by the “Signal Filter” or “Signal Filter Delay” function.
6. During long-time measuring, “Compression” function can increase the memory’s efficiency.
7. Trigger condition depends on the device under test. If trigger can’t be activated, try to widen the trigger conditions.
8. If the frequency of device under test is out of the range of internal sampling frequency of LA, use the external
frequency as the external sampling frequency.

3.2.3 Hardware(H) Menu
LAP-C Series
LAP-D Series
Normal Mode: It is the default Mode.
Double Mode: In the Double Mode, the RAM size will be double of the highest RAM size. Take LAP-C(32128) as an
example, its highest RAM size is 128K; after the Double function is activated, the RAM size will be up to 256K. For
models of 32 channels, channels 1-16 will use the RAM size of channels 17-32 to capture large data. Models of 16
channels have no such limitation. If users need more RAM size (larger than 128K) but the quantity of channels is less
than 16, then they can activate the Double Mode, or set trigger page, or use higher level models. LAP-C(16064) and
LAP-C(16032) models don’t support the Double Mode.
Compression Mode: Compress the signal realtimely without data damaged. With compression technology, more
sampling data can be stored in the limited RAM size, with higher resolution and not wasting RAM size. The
compression rate of Zeroplus Logic Analyzer can be up to 255 times. That’s mean when the RAM size is 128K, each
channel can store as much as 32 M bits(128K*255) data. The compression rate is subject to the data.
Note: For models of 32 channels, after compression activated, the quantity of channels will be reduced to 24, that’s
mean only channels 1-24(A0-C7) are available, channels 25-32(D0-D7) have no function. Compressed data is larger
than uncompressed data. The compressed data will be decompressed after transmitted into the computer; its
decompression time is determined by the computer operating rate. Models of 16 channels have no such limitation.
