electrocution and can damage the internal components.
Please connect the grounding end correctly: please do not connect the grounding
end to the power source to prevent damage to the logic analyzer and computer.
Please do not use oscilloscope in high temperatures and high humidity environments
or near flammable materials. This is to prevent damage to the logic analyzer.
If the instrument will not be used for a long time, please remove the USB cable to
conserve power.

4. Software Installation
The attached CD contains the LA installation software. The file name is
“LA_Install_V1.xx.exe” and the xx is the edition number. You can also download the
installation software from the Perytech website. Implement to install the software.
Software installation is very simple. Just press “Next.” The driver will also be installed
together. After installation is complete, an “LA” shortcut will appear on the desktop
and in the start function, as shown below.

5. Logic Analyzer Software Operating Instructions
5.1. Quick start
Click the LA shortcut on the desktop to activate the LA software. The following figure
is the software screen for the 32 channel model logic analyzer. If the instrument is a 16
channel model then the channel number would be 16. Except for the different
number of channels, the operating method for the 16 and 32 channel logic analyzer is
the same.

Basic operation of the logic analyzer requires only two steps:
1. Setting trigger conditions: click the Trig box (where the mouse cursor is in the
below figure) to set the trigger condition. Here we set the trigger condition as
Channel A0 rising edge.
2. Press the “Run” button.
After pressing the “Run” button, the logic analyzer will start to detect trigger signals.
When the trigger signal appears, the analyzer will transmit the data from the logic
analyzer back to the PC. The PC screen will show the waveform.
The “Repeat Run” next to the Run button is used to repeat the Run. If you wish to
stop, press the “Stop” button on the side at any time.

5.2. Setting the trigger condition
Click the Trig box (where the mouse cursor is located in the following figure) to set the
trigger condition. Click the mouse’s left button to cycle and change the trigger
condition. Click the mouse’s right button to display the trigger menu, shown below.
The menu can be used to select trigger conditions.
There are six trigger conditions to choose from: None, Rising Edge, Failing Edge,
Either Edge, High, and Low.
Because edge trigger (rising edge, failing edge, and either edge) is an instant action,
only one channel can be set at the edge trigger at the same time. Multiple channels
can be set at the same time for the level trigger (High, Low). Only when the signal
satisfies all set conditions will the logic analyzer be triggered.
The trigger point is indicated by the red T cursor, as shown below. You can also use Alt
+ T to move the screen to the trigger point position.

5.3. Setting the size of the memory and the sampling rate
Use the “RAM Size” and “Sample Rate” pull down menu in the toolbar to select
memory size and sampling rate, as shown in the below figure.

5.4. Setting trigger position
Use the “Trig Position” pull-down menu to select the trigger position, as shown below.
For example, if you select 20%, the trigger point will be in the front 20% position of all
the data. The default value is 10%.
Sometimes the trigger will be in front of the set position. For example, the trigger
setting is at 50%, but the trigger point is at the 20% position. This is because the
memory has not yet filled in the data in front of the 50% before the trigger signal
appeared. Thus, there will be less data before the memory. You can set it so that the
memory must be filled in before trigger can be activated. Open Tools → Option. Open
the Option window, as shown below. The Trigger Position default setting is “the
trigger condition occurs.” Change this to “the trigger condition occurs and the
memory is filled.” This way, the hardware will wait for the memory to be filled in
before detecting the trigger signal.

5.5. Screen scaling
There are five ways to scale the screen:
1. Press the Ctrl key + mouse roller
2. Use the buttons in the toolbar
3. The “+ -” keys on the keyboard
4. Use the button in the toolbar. The function of this is to magnify the part
frame-selected with the mouse
5. The function of the button in the toolbar is to shrink all the waveforms into
the screen.

5.6. Move screen
Press the right mouse button to drag the screen, as shown below. The mouse roller
can also be used scroll the screen.
The left /right button on the keyboard can also be used to move the waveform. Each
moving distance is one large grid. The Page Up/Page Down can also be used to move
the move waveform. The distance of each move is approximately 10 large grids.

5.7. Move the previous/next waveform edge
The buttons in the toolbar can move the screen to the previous/next edge of
the waveform. This is useful for searching the waveforms. First, select the channel on
the left side Channel Panel (as shown below). Then press to move to the
next/previous edge of the waveform. The hot key is the “Ctrl + Left/Right” keys.

5.9. Channel editing (add, delete, rename)
There are many channel editing functions on the “Channel Panel”on the left side of
the screen. Click the mouse’s right button on the channel and a menu will be
displayed, as shown below. This menu can be used to add/delete channels, edit the
channel name, or change the channel color. The left mouse button can be used to
drag the channel. The mouse can also be used to adjust the channel height.

5.10. Cursor function
Click the right mouse button on the rule area above the waveform will show the
cursor menu, as shown below. You can place the A/B cursor or go to the A/B/T cursor
position (T: trigger cursor). You can also go to the beginning and go to the end
position.
Press the left mouse button to drag the cursor, as shown below. The cursor will
automatically align the waveform edge. If the mouse cursor moves close to the
waveform edge when dragging the cursor, the waveform’s edge will display green, as
shown below. If the left mouse button is released at this time, the cursor will
automatically align the edge.

5.11. Bus decoding function
Press Ctrl + left mouse button on the left side Channel Panel to select the channel.
The selected channel will turn greyish-blue, as shown below. Press the mouse’s right
button to display the channel operation menu. Choose “Group Into Bus.”
Then the selected channels will be integrated into a bus, as shown below. Because the
bus decoding is not set, the displayed channel is in hexadecimal value.
