I. Overview

1、 Basic knowledge

Logic analyzer is the instrument that collects and displays the digital signal from the devices under test. It is mainly used for timing judgement an analysis. Unlike the oscilloscope with many voltage grades, It has only two grades(Logic one and Logic zero). .After the reference voltage is set, the logic analyzer could decide from the test signal that the signal above the reference voltage is logic one, and the signal below is logic zero. The digital waveform is formed with 1 and 0. Compared with the oscilloscope, when testing and measuring the digital systems like MCU, ARM, FPGA and DSP, the logic analyzer could provide better accuracy, much more data and more complicated measuring methods.

For example, if you are sampling a signal with the logic analyzer, the sample rate of which is 1Mhz, and the reference voltage(Threshold voltage) is set to 1.5V, the logic analyzer would compare the current voltage with 1.5V. The signal above 1.5V would be high level(logic 1), and the signal below 1.5V would be low level(logic 0). Thus we get a sample point, and then we could link all these points(logic 1 and logic 0) to get a waveform, in which the user could see and analyze the timing of the signal, logic errors and the relation between each other.

The figure below shows how the logic analyzer samples the signal:

2、 Product series

Kingst logic analyzer product family consists of two series: the LAx016 series with sampling memory and LA1000 series without sampling memory.

LAx016 series is integrated with large-capacity memories. The sampled data would be saved in the internal memory while the device is sampling the signal. After the sampling process the data would be sent to the computer, and it would be restored back to original waveform and analyzed. As the sampling memory could offer the sampling bandwidth that is extremely high, so the device could sample all the channels in high sampling rate. This series consists of LA5016 with the highest sampling rate of 500M, LA2016 with the sampling rate of 200M and LA1016, the sampling rate of which is 100M.

Sampling memory doesn’t exist in LA1000 series. When the device is sampling the signals,

the data will be sent to the computer at the same time. The PC software compresses and the data and saves them in PC memories, and then it would restore the waveform and analyze it. As the data needs to be sent to the computer and saved in real time, so the bandwidth is limited to the USB2.0 speed, that is, 480Mbps. As a result, when the device works with high sampling rate, only some of the channels could be used. If you want to use all the channels, you have to reduce the sampling rate. This series consists of LA1010 with with the highest sampling rate of 100M and LA1002, the sampling rate of which is 24M.

II. Brief introduction to Kingst VIS

1、 How to install software

Kingst virtual instruments software Kingst VIS could be found in the attached CD, or downloaded from the web page: http://www.qdkingst.com/en/download. And the software package is something like KingstVIS_Setup_v2.0.0.exe (v2.0.0 represents the version).

Double click the package file to execute the installation program. The procedure is similar with the common software in windows, and there are instructions that you could follow in every step. In the last step, you should install the driver program of hardware device, and you will see the dialog as the figure below(there could be differences between different OSs). Please select “Install” to complete the procedure.

After the install procedure is complete, a shortcut like would be created in the start menu and desktop, and then the Kingst VIS software could be accessed with this shortcut.

2、 Brief introduction to GUI

When the software is started through start menu or desktop shortcut, you will get a screen similar to the figure below. The detailed information of the software would be introduced in Chapter 4, and here is only a brief introduction.

As shown in the figure above, the software interface could be divided in several parts:

①. Tools bar：top of GUI, including common settings of the current device and the main menu

button of the top right corner.

②. Device and channel settings: left side of GUI, shows selected or connected device type,

and next is the number and name of current measurement channels.

③. Waveform display window: middle of GUI, the topmost is the timeline. The sampled

waveform displays in the middle and a scroll bar is below it.

④. Sampling result analysis window: right side of GUI, the top half shows measurement

results that are frequently used, and you can add analyzer decoder and see the results on the

bottom half.

3、 Language switch

The Kingst VIS software could display in “English/简体中文”. If you want to change the language, please press the “Options” button in the top right corner, move the mouse to the menu item “Language”, and select the language. The selection would become effective after the software is restarted.

4、 Brief introduction to the demo function

The software could provide demo function. You can simulate the functions without the actual hardware, and you could get a good experience of the software through this function.

All Kingst virtual instruments share the same Kingst VIS software. As shown in the right figure, there is a device control bar on the left side of the software. The icon of left side represents that logic analyzer is the current device, and the text in the middle means the selected device is LA1002. If you press the first button on the right side, as the right figure shows, you could see all the devices supported. You could select any device that you want. After you press “OK”, you could evaluate and

experience the device that you selected.

After the “Simulate” button on the toolbar is pressed, the software would simulate the work process as the actual device exists. And the software would eventually display some square wave or pulse signals.

One of the key functions of the logic analyzer is that, it could analyze the signal that complies with some standard protocol. Here we take SPI as an example, to give a brief introduction. Find the “Analyzers” on the right side of GUI, press the “+” button, and select “SPI” from the popped menu. We will get a analyzer settings dialog, the settings on which are default. Next we can press the “Simulate” menu on the toolbar, and we will get the SPI signal waveform on the channels 0-3, with the analyzer result. And other channels still show random square wave or pulse signal(as the figure below shows).

If you click the left button without releasing, you could drag the waveform. More details are covered in following chapters.

III. Connect the device

1、 Connect the device to PC

When the installation process is completed, the logic analyzer can be connected to PC through the attached USB cable (In case of desktop computer, use the USB port behind the tower box). Then the computer would report that new hardware has been found. In Windows XP, there would appear a driver installation dialog, and just select to install automatically. In Windows 7/8/10, a dialog would appear in the top right corner of the screen. Then the install process would start automatically, and we just need to wait for a while. After the installation process is completed, a new device called “Kingst Instrument-Logic Analyzer” would appear in “Device Manager->Universal Serial Bus”.

After the device is connected to PC and the driver has been installed, the device would be connected automatically when we open the software. When the connection is complete, as shown in the right figure, the device bar on the top left side of GUI would display current device type. The icon on the left side means that the current device is a logic analyzer. And through the two buttons on the right side, you could select other devices or change the settings of current device. The detailed information would be introduced in chapter 4.

Besides, the status bar of the bottom left side shows the connection status of current device. “Device connected” means the device hardware has been connected to PC successfully and ready to work, while “Device unconnected” means the device hardware is not connected to the USB port of PC, or because there is something wrong, the device could not work normally.

2、 Connect the device to system under test

Please note that the logic analyzer and the computer share the same ground, so the voltage between the GND of system under test and the GND of the computer should be zero. Especially when the system is connected to the force electricity, please make sure the isolation is made. If devices with force electricity like frequency transformer are not isolated through the isolation transformer, the system would be connected to the force electricity. And if you connect the logic analyzer to such a system, the logic analyzer even the computer would be broken. And the damage could be beyond repair, so the isolation should be made in advance.

When the logic analyzer is connected with the system under test, you should first connect the GND channel to the system under test, and then connect the signal channels. There are 16 channels in the logic analyzer. It means that up to 16 digital signals could be tested simultaneously. If the number of existing signal is less than 16, the channels could be selected at will. The channel numbers of the software correspond to that of the hardware device.

In addition, when measuring the signal with high speed, the measuring lines of logic analyzer
