4. Software Installation
The CD that comes with the machine has a DSO software installation file. The name of
the file is “DSO_Install_V2.xx.exe.” The “xx” is the edition number. The installation file
can also be downloaded from the Perytech website. Once executed, the program will
start to install the software.
Software installation is very simple. Just press the “Next” and the driver will be
installed together. Once installation is complete, the desktop and Start Menu will have
a DSO shortcut, as shown in the following figure.

5. Oscilloscope Operating Instructions
5.1. Quick start
Click the DSO shortcut on the desktop to activate the DSO software. The DSO
software home screen looks like the following figure (the yellow words and the frame
are added for description purpose). The following describes the various functions.
5.1.1. Channel selection
The two buttons on the top right side are the channel selection button, as shown
below. Channel selection buttons are used to select the desire channel. The selected
channel button will turn red. There are two channels when connected to a DSO so
there are two buttons. When connected to two DSO, there will be four channels and

four buttons. A maximum of four DSO can be connected, which has a total of eight
channels and eight buttons.
.
5.1.2. Main function keys
Below the channel selection buttons are the main function keys, as shown in the
below figure. The main function keys are used to select the main functions to be
implemented. The RUN/STOP button is to run or stop the oscilloscope. The AUTOSET
button is to automatically set the appropriate voltage and time selection.

5.1.3. Sub function menu
The sub function menu, as shown below, is on the left side of the main function keys.
Just click to implement. Some main functions have a sub function menu. Select
different main function keys and different sub function menus will appear. When the
font is green (Channel 1 color), this means that the menu has CH1 sub functions. Red
font (Channel 2 color) means the menu is for Channel 2 sub functions. You can use the
channel selection button to select the channel you desire. White font indicate sub
functions not related to any channels.
There are two knobs below the main function keys, as show in the following figure.
The left side is used to adjust the voltage range and the right side is used to adjust the
time range. Clicking the knob with the left button of the mouse and moving the knob
up is to increase the setting. Moving the knob down is to decrease the setting. User
can also use the “+” or “-” below the knob for control. Voltage range is controlled
individually by each channel. When the CH1 is selected, the adjusted voltage range is

沛瑞科技股份有限公司 TEL:[phone]
www.perytech.com Peregrine Technology CO., LTD. FAX:[phone]
11
the Channel 1 voltage range. When CH2 is selected, the adjusted voltage range is the
Channel 2 voltage range. The time range is controlled with all the channels.
The Mark 1 and 2 tags on the left side of the screen is the channel’s benchmark point.
The mouse can be used to drag the tag up and down to move the wave pattern.

5.2. Setting the trigger function
Press the TRIGGER in the main function keys and the trigger function sub function
menu will appear, as shown in the following figure. Description is below.
5.2.1. Setting the trigger source
The Source menu function is for selecting the trigger channel. Selectable channels
include Ch1, Ch2, and the Ext (external trigger). The input point for the external
trigger is on the front panel. The red rectangle in the below figure shows its position.
5.2.2. Setting the trigger slope
Slope menu function is used to select the trigger’s positive falling edge. Click this can
change the rising edge or falling edge trigger.

5.2.3. Setting the trigger mode
Mode menu function is for setting the trigger mode. There are three trigger modes to
choose from:
Auto: auto mode. After a period of time with no trigger, the system will automatically
obtain the wave pattern. This is the most commonly used mode.
Normal: normal mode. The wave pattern will only be obtained when triggered.
Single: stops after being triggered one time.
5.2.4. Adjusting trigger level
The arrowhead on the right side of the screen is used to adjust the trigger level, as
shown in the yellow frame in the following figure. The left button of the mouse can be
used for dragging. When the trigger channel is set at CH1 the arrowhead is green
(CH1’s color). When the trigger channel is set at CH2 the arrowhead is red.

5.3. Display function setting
Press the DISPLAY in the main function keys to see the display sub function menu.
There are two pages to the display sub function menu, as shown below. Select Next
Page at the bottom of the menu of Prev Page to switch pages. The following describes
each menu function.
5.3.1. Wave pattern display switch (Display On/Off)
CHx Display menu can be used to turn on and off the wave pattern display. The
default is to display when turned on. Click to switch to off. When the channel is in Ch1,

the control is displayed in Ch1. When the channel is in Ch2, the control is displayed in
Ch2.
5.3.2. Coupling setting (DC/AC)
Coupling menu can control the input signal DC or AC coupling. The default is the DC
coupling. When choosing the AC coupling, the DC signal will be filtered out and only
the AC signal kept.
5.3.3. Probe setting
Probe menu can be used to set the probe. The menu will appear after being clicked,
as shown below. There are six choices (1x~1000x).

5.3.4. Band width setting
BW menu is used to set the band width of the channel. The default is Full, but can be
switched to 20MHz band width.
5.3.5. Zoom related functions
There are three zoom function menus. The Zoom In and Zoom Out is used to magnify
and shrink the wave pattern. The roller of the mouse can also be used for control.
After zooming in, the scroll will appear at the bottom of the screen that can used to
move the screen.
The Zoom menu at the very top is used to change the magnification target (wave
pattern or FFT). The default value is the grey “Wave,” which is also magnifying the
wave pattern. Grey means that it cannot be switched. When the FFT function is on, the
color of the Wave will change to white, indicating that it can be changed.
When changing to FFT, the shrinking target is the FFT, as shown below.

function. The default is OFF. This function also includes switching between CH1 and
CH2 and will separately display Channel 1 and Channel 2 FFT.
The screen after turning on the FFT is shown in the below figure. You can use the “F”
tag on the left side of the screen to move the FFT wave pattern.

The XY mode is used to display the Lissajous curve. After turning on this mode, the
oscilloscope wave pattern will turn off and display the white Lissajous curve, as shown
below. If the user wishes to simultaneously display the oscilloscope wave pattern and
the Lissajous graphic, the user can change the setting in the “Options” (please see
5.6.7.4 for curve).
