I. PC Software USB Driver Install Guide
Use the supplied USB cable to connect the oscilloscope with a PC through their USB ports.
Note: If you use a USB cable that is not supplied by us, some problems such as connection error and signal disturbing might
occur.
For Windows Vista\Windows 7\Windows 8
The Microsoft Windows Systems since Windows Vista, Windows 7 or Windows 8, change a lot, which require a new installation guide of USB driver. Here it is.
During the whole installation, please assure that the device is running well and plugged into PC from USB.
Right click [Computer], you can find it on the desktop, or in [Start] menu.
in the pop up menu, click [Manage] and it will open a window named "Computer Management", as follow, in the left side click [Device Manager], it will show a devices tree in
the middle, and then click the last one button "Scan for hardware changes" in tool bar as follow, and if the device is running well and plugged into PC, computer will detect an
unknown device with a "!" icon.
Right click the unknown device icon, in the pop up menu click [Update Driver Software...],
In the open window, select [Browse my computer for driver software],

2
The next window, select a directory path for the driver software location, and click "Next",
Notice: the driver software location is a directory that is under the software setup folder named "USBDRV" (For Windows 8, the location is USBDRV\USBDRV_win8), and the
contents inside are like these:
Or like this, than you should use the "USBDRV" directory to indicate the ".inf" file, and to the ".sys" or ".dll" file, you can indicate then in different directories like "x86", "ia64" or
"amd64" depending on the CPU, but most of time just x86 and amd64 are enough.

3
OK, back to the driver installing, after last "Next" step, the system is installing driver software for you, as follow,
In the course,
It(for Windows XP x86&x64, Windows Vista x86&x64, Windows 7 x86) may open a window named "Windows Security" as below, and just select "Install this driver software
anyway" to continue,

4
Or sometimes it(for Windows 7 x64) may open a window named "Windows Security" as below, and just click "Install" to continue,
And then continue installing,
And finish.
Now a successful installation window opens with information "Windows has successfully updated your driver software".

5
Close the window, have a look at the "Computer Management" window, you will find a device under [LibUSB-Win32 Devices], it should be like this:
Now the USB driver will work.
For Windows XP\Windows 2000
Notice: for both x86 and x64.
Plug into the running well device to open [Found New Hardware Wizard] dialog.
Or you can right click [My Computer] and select [Manage], in the left area of opened [Computer Management] select [Device Manager] , double click the item [USB Device]
with "?" in the middle area to open the Wizard,

6
In the Wizard, select [No, not this time] ,
select [Install from a list or specific location(Advanced)] ,
select [Search for the best driver in these locations.] , then select [Include this location in the search] and indicate a directory location for USB driver which is named as
"USBDRV" and under the directory where you installed the program at,

7
Then the installation is running,
And complete,
And prompt as installed,
And show installed in [Device Management],

8
Now you can use the program and use if for USB communication.
If there is an early version of USB driver in your computer, you could try running "reinstall.bat" to fix, the file is under the directory of "USBDRV".

III. Operations Instruction
Relevant operations of this software.
1.How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of oscilloscope:
(1) Click to show the Function menu, choose "Channel".
(2) Click to select the channel that the probe connects with (CH1 or CH2).
(3) Set "Probe Rate" to the proper value corresponding to the probe.
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe in the software is preset to X10.
Make sure that the set value of the attenuat
ion switch in the probe is the same as
the menu selection of the probe attenuation coefficient in the software.
The set values of the probe switch are X1 and X10.
Figure: Attenuation Switch
Caution:
When
the attenuation switch is set to X1, the probe will limit the bandwidth of the
oscilloscope in 5
MHz. To use the full bandwidth of the oscilloscope, the switch
must be set to X10.
2.How to Set the Vertical System
You can set the corresponding parameters of vertical system in the Channel window (18/19 in II. User Interface).
In the voltage division list, you can select the proper value. Take VDS3102(L) for instance.
You can set the zero point position through the control bar to regulate of the vertical display position of the signal. You can also drag the zero
point position pointer (22, 23 in II. User Interface).

12
Drag the slider up to increase, down to decrease; the further from the center, the higher the changing speed is.

Q: The voltage division of Channel 1 decreases one level
A: The voltage division of Channel 1 increases one level
W: The voltage division of Channel 2 decreases one level
S: The voltage division of Channel 2 increases one level
Cymometer
It is a 6-digit cymometer. The cymometer can measure frequencies from 2 Hz to the full bandwidth. Only if the measured channel has triggering
signal and in Edge mode, it can measure frequency correctly. In the Single trigger mode, it is a one channel cymometer and it can only measure
the frequency of the triggering channel. In the ALT trigger mode, it is a two channel cymometer and it can measure the frequency of two
channels.
3.How to Set the Horizontal System
You can set the corresponding parameters of horizontal system in the Capture&period window (17 in II. User Interface).
You can use Horizontal Trigger Position control bar to adjust the horizontal position of the signal in the waveform window. You can also drag the
red pointer to adjust it (3 in II. User Interface).
Note: Different models have different ranges of time base, just take VDS3102(L) for instance here.
The further from the center, the higher the changing speed is.

4.How to Set the Trigger System
Trigger determines when VDS starts to acquire data and display waveform. Once trigger is set correctly, it can convert the unstable display to
meaningful waveform.
When VDS starts to acquire data, it will collect enough data to draw waveform on left of trigger point. VDS continues to acquire data while waiting
for trigger condition to occur. Once it detects a trigger it will acquire enough data continuously to draw the waveform on right of trigger point.
Click to show Function menu, choose "Trigger".
You can also click in the right bottom window to show it.

13
Trigger Control
The oscilloscope provides two trigger types: single trigger and alternate trigger.
Single trigger: Use a trigger level to capture stable waveforms in two channels simultaneously.
Alternate trigger: Trigger on non-synchronized signals.
The Single Trigger and Alternate Trigger menus are described respectively as follows:
Single trigger
1. In Trigger menu, choose "Single" (the chosen label has a mark).
2. Choose Source.
3. Choose Mode.
Single trigger has four modes: edge trigger, video trigger, slope trigger and pulse trigger.
Edge Trigger: It occurs when the trigger input passes through a specified voltage level with the specified slope.
Video Trigger: Trigger on fields or lines for standard video signal.
Slope Trigger: The oscilloscope begins to trigger according to the signal rising or falling speed.
Pulse Trigger: Find pulses with certain widths.
The four trigger modes in Single Trigger are described respectively as follows:
Edge Trigger
Choose Mode as "Edge". An edge trigger occurs on trigger threshold value of input signal. Select Edge trigger mode to trigger on rising edge or
falling edge.
Set in Trigger menu:
(1) Choose "Rise" to trigger on rising edge.
Choose "Fall" to trigger on falling edge.
(2) Click the voltage value after "Trigger" to show slider bar. You can also drag "13. Trigger point" in II. User Interface .
(3) Choose Trig Mode.
Auto: Acquire waveform even no trigger occurs.
Normal: Acquire waveform when trigger occurs.
Single: When trigger occurs, acquire one waveform then stop.
(4) Set Hold Off: When trigger occurs, acquire one waveform then stop (100ns - 10s).
Setting method: "+", "++", "+++" is the position of digit that will be changed. "+" represents the last digit, "++" represents the middle digit,
"+++" represents the first digit. Eg. When "+" is chosen, click ▲, the last digit will be increased by 1.
Click "Reset" to set Holdoff time as default value (100ns).
Set in Trigger window:
Force: Force to create a trigger signal and the function is mainly used in "Normal" and "Single" mode.
