1. Introduction
With this unique device, you will have the basic devices needed for fault detection of electronic
boards: Oscilloscope, curve tracer, signal generator and short circuit finder.
UCE-DSO4200C can transmit all data to a PC via USB connection. This USB connection provides the
possibility to use the device with PC software.
In addition, this device can mirror the LCD screen image to a monitor via the HDMI output and can
be controlled with a wireless mouse.
In the curve tracer mode, passive elements can be checked without triggering active elements with
a 0.2V test signal. Thus, less component disassembly is ensured in troubleshooting.
In short-circuit finder mode, the short-circuit line on the PCB can be analyzed and its location can
be found.

2. Device Overview
There is a 5-inch LCD on the device. LCD has resistive type touch. While general control of the device can be
made on the screen, it is also possible to perform basic controls more quickly with 3 rotary encoders.
Additional features are gained with the buttons on the rotary encoder.
At the bottom of the device, there are curve tracer measurement tips. These are 4mm banana compatible
probe inputs. There is one BNC connector for signal generator output and 2 BNC connectors for
oscilloscope measurement input (Figure 1).
Figure 1. Front view of the device
There is an HDMI output on the right side of the device. It is used to mirror the LCD image to any monitor,
projector or TV. The USB connection is used to communicate with a computer (Figure 2).
There is a power input on the back of the device. The power supply of the device is provided by a 12V - 2A
adapter. The device is turned on and off with the power switch (Figure 2).

3. Oscilloscope Mode
To enter the oscilloscope mode, the "OSCILLOSCOPE" icon in the "Main Menu" is clicked. The general view
of the scope mode is as in Figure 4.
Oscilloscope icon
At the top of the screen; Status information of measurement channels (Volt/div, coupling), operating
status, time base mode, trigger status information, sampling status information (time/div), frame refresh
rate and battery status information are included. On the right side, there is the menu area where various
settings are made. At the bottom of the screen, there are submenu of these setting menus.
When returning to the main menu with the “EXIT” button in the lower right corner of the screen, the
setting parameters are saved in the memory (dso_settings.cfg).

3.1. Adjusting the vertical system
The UCE-DSO4200C has two analog input channels and each channel is equipped with an independent
vertical control system. The adjustment methods for the vertical systems of the two channels are the same.
This section takes CH-1 as an example to introduce the vertical system adjustment method.
Enable or disable analog channel:
Click the “CH-1” button in the menu to enable CH-1. While the “CH1-ON”button in the submenu enables
the channel, the “CH1-OFF”button makes the channel disable. In the figure below, CH-1 is disabled and CH-
2 channel is enable. No status information is displayed on the disabled channel.
If CH-1 is enabled but not activated, the channel status label is shown as below. Click the “CH-1”menu in
the menu to activate the channel. Other methods of channel activation are when the vertical scale setting
of the corresponding channel is made or if the rotary encoder button is clicked, the channel is activated.
CH-1 enabled but not active
CH-1 enabled and active
Vertical scale setting:
Vertical scale indicates the voltage value per grid in the vertical axis of the screen. It is often expressed in
V/div. While you adjust the vertical scale, the display amplitude of the waveform would enlarge or reduce.
The scale information of the channel status label (e.g., as shown in the following figure) at the top of the
screen would change accordingly.
The adjustable range of the vertical scale is between 5 mV/div and 10 V/div. Turn the Rotary-1
corresponding to CH-1 to adjust the vertical scale (clockwise to decrease the scale and counterclockwise to
increase). The vertically scaled channel becomes the active channel at the same time.
Vertical offset adjustment:
Vertical offset indicates the offset of the signal ground level position of the waveform from the screen
center in the vertical direction. When adjusting the vertical offset, the waveforms of the corresponding
channel moves up and down. As it moves, the offset level is shown on the screen with a horizontal line, and
the vertical offset information (as shown in the figure below) will change accordingly just above the offset
level line.
