Preface
This Quick Start Guide is designed to help new and intermediate users navigate and
perform common tasks with the Logic Analyzer. Despite its simple packaging and
interface, the Logic Analyzer is a sophisticated measurement and analysis tool. It is also
a highly sensitive electrical current sensing device. Users must carefully read
instructions and procedures pertaining to installation and operation. Any instrument
connected to the unit should be properly grounded. A pair of anti-static gloves is strongly
recommended when performing a task with the device. To ensure accuracy and
consistency of output data, use of the bundled components is strongly recommended.
User opinions are very important to us. Please contact our engineering team by
telephone, fax or email with your questions or feedback. Thank you for choosing the
Logic Analyzer.

signal of DC3.3V. When the upload is finished, a
Falling Edge signal is sent.
When a trigger condition is established, the T_O will
send a Rising Edge signal of DC3.3V. When memory
is full, a Falling Edge signal is sent.
When a user initiates a sampling task by clicking the
RUN icon in the window or clicking the START button

1.4 System Requirements
This section discusses basic operating system and hardware requirements for the
Logic Analyzer. Software and hardware capabilities may vary depending on PC
configuration,. This manual assumes proper installation of a supported operating
system as listed below.
1.4.1 Operating System Requirements
In this sub-section, we share our experiences testing the Logic Analyzer on the
following Microsoft Windows operating systems. Since the Logic Analyzer requires
operating system support of the USB protocol, Windows 95r2 and earlier OS versions
are incompatible.
1) Windows NT 4.0 Workstation & Server, Service Pack 6 – not recommended
2) Windows 98, 98 Second Edition - supported
3) Windows ME – not recommended
4) Windows 2000 Professional, Server Family - supported

dielectric strength or surface resistively’.
Pollution Degree 1: No pollution or only dry, non-conductive
pollution occurs. This pollution has no effect.
Pollution Degree 2: Normally only non-conductive pollution
condensation must be expected.
Pollution Degree 3: Conductive pollution occurs or dry,
non-conductive pollution occurs which becomes conductive due
to condensation. In such conditions, equipment is normally
protected against exposure to direct sunlight, precipitation and
wind, but neither temperature nor humidity is controlled.

Hardware Installation
Hardware installation simply involves connecting the Logic Analyzer to your
computer with the included USB Cable as shown in Figures 2-4 and 2-5.
1. Plug the fixed end of the cables into
the LA (Fig.2-1).
Fig. 2-1
Fig. 2-2
2. Plug the loose ends into the
connectors on the circuit board to be
analyzed (Fig.2-2).
Note: The following sequence must be
observed when connecting the
connectors into the circuit board: A0 =
Brown, A2 = Red, A3=Orange and so on.
3. The circuit board must be grounded to
the Logic Analyzer with the connecting
cables (Fig.2-3).
Fig. 2-3
Step 1 - Plug the thin male end of the USB cable into the laptop or PC.
Step 2 - Plug the square female end into the logic analyzer.

2.2 Tips and Advice
1. When testing a circuit board, make sure that the internal sampling frequency (within
the Logic Analyzer) is at least four times the external board frequency.
2. If the signal connector does not work well with the pins on the test board, try using the
supplied probes.
Fig. 2-7: Probes supplied with us .

insert it into the clip.
Fig. 2-8
3-2. Compress the probe as shown to
reveal 2 metal prongs (Fig.2-8).
3-3. Place the metal prongs on a metal
connector on the motherboard and
release the fingers so that the
prongs grip the metal connector
(Fig.2-9).

User Manual
4. The Logic Analyzer will connect to Web server for software updates if an internet
connection is available.
5. Unwanted signals can be filtered out using the Enable or Enable Delay functions.
6. When measuring for a long period, Compression makes memory more efficient.
7. Trigger condition depends on the test board. If triggering does not work well, try
narrowing the trigger conditions and optimize them repeatedly.
8. If a test board has a lower frequency than Logic Analyzer, sample signals according
to the external clock.
9. When clocking by an external clock, filter extra signals with the Enable function.
10. Unused channels may be removed from the Bus/Signal display using Bus/Signal
(Menu) Channel Setup.

Introduction to Logic Analysis
Chapter 3 gives detailed instructions in performing two basic analysis operations
and five advance analysis applications with the Logic Analyzer. The basic analytical
operations are the Logic Analysis and the Bus Analysis, which are fundamental to all
further applications.
2.4 Logic Analysis
Logic Analysis is meant for a single signal analysis. Section 3.1 gives detailed
instructions on the software’s basic setup.
Basic Software setup of the Logic Analysis
Task 1. Clock Source (Frequency) and RAM Size set up
Step 1. Click icon or Click Sampling Setup from Bus/Signal on the menu bar,
the dialogue as shown in Fig 2-1 will appear.
Fig 3-1 – Clock Source
Logian-16 User’s Manual Page 21
Step 2. Internal Clock (Asynchronous Clock)
Click on Internal Clock, and then select the Frequency from the pull down
menu to set up the frequency of the device under test (DUT). The frequency
of the Internal Clock must be at least four times higher then the frequency
of the Oscillator on the DUT. Or, select the frequency from
the pull down menu on Tool Bar as Fig 3-2 shows.
Tip: Connect the signal output pin of the tested board to the Signal connector of
Logic Analyzer to measure it using the internal clock of Logic Analyzer.

External Clock (Synchronous Clock)
Click on External Clock, and then select “Rising Edge” or “Falling Edge” as the
trigger condition of the DUT. In the Frequency column, type the frequency of
the oscillator on the DUT.
Tip: The External Clock is applied when the frequency of the oscillator on the
tested board is less then 100MHz. Connect the output pin of oscillator on the
tested board to the CLK pin of Logic Analyzer as shown in Fig 3-3.

Tip: There are four commonly used preset voltages for Trigger Level, TTL,
CMOS (5V), CMOS (3.3V), and ECL. Users also may define their own
voltage from -6V to +6V to fit with their DUT.
Port A represents the pins from A0 ~ A7 on the signal connector of the Logic
Analyzer, and so do Ports B, C and D. The voltage of each port may be
configured independently.
