Page 3: Before First Time Use
DN112-06v02 Before First Time Use Introduction DSO112A is based on DSO112 with re-designed schematic and PCB. While keeping all functions and performance of its predecessor it exhibits significantly higher vertical sensitivity and ultra low background noises. As a small, light, accurate, and battery operated oscilloscope DSO112A is best for portable or field use. -
Page 4: Charge Battery
(photo below). The LED can be seen from outside of enclosure. After charge is completed the LED will turn off. To avoid waste of battery power DSO112A is with automatic Auto Power-off shut-down feature. When the unit is running on battery and there is no touch activity detected for a certain period of time the oscilloscope will shuts down itself. -
Page 5: Connectors
Trigger Position Indicator Indicating trigger position inside capture buffer which is represented by the green brackets. The following figure shows the functions and types of DSO112A Connectors connectors. Please note that the Test Signal Output connector is dual functional. It becomes external trigger input when external trigger is selected. -
Page 6: Power Button
Press the Power Button when battery or USB power has been connected. To Power Off DSO112A can be powered off in three ways: Ø In the main working screen touch the “Menu” button at top-left corner and select “Pwr Off” button. -
Page 7: State Navigation
DN112-06v02 State Navigation The following diagram shows the relationship of major working states. Tip: DSO112A uses resistive LCD panel. It will have better effects to operate with fingernail instead of finger belly as in operating a cellular phone. Booting Sequence When power button is pressed the oscilloscope is powered up. -
Page 8: Adjust Sensitivity And Couple
You need to adjust signal or oscilloscope parameters to make trigger happen in order to see waveform refresh. This mode is useful for capturing sparse signals. The temporary frozen effect makes sparse waveform stay on screen instead of just flash across. JYE Tech - 8 - www.jyetech.com... - Page 9 Vice versa, you will see more waveform before trigger. For DSO112A trigger position can be chosen to 1/8, 1/4, 1/2, 3/4, or 7/8 of capture buffer.

Page 10: External Trigger
When trigger mode is set to SING HOLD state will be entered automatically if valid trigger is detected. For DSO112A record length can be set to 512 or 1024 points. Select Record Length To change record length enter “Select Timebase” screen as stated in “Adjust Timebase”... -
Page 11: Advanced Operations
Recall Waveform Saved waveform can be recalled and displayed on screen without any change. To do this enter Menu and touch the button “Recall WF”. Recalled waveform is always displayed in HOLD state. JYE Tech - 11 - www.jyetech.com... -
Page 12: Send Waveform Data
Connect DSO112A oscilloscope to an USB port on PC. DSO112A contains a Uart-USB bridge CP2102. You need install driver on the PC for this chip if you are the first time using the PC for DSO112A. Please go to Silicone Lab website www.silabs.com to download the appropriate driver for your system and install it correctly. - Page 13 DN112-06v02 Select the port that is corresponding to DSO112A (you can identify it by going to Windows hardware manager and connecting/disconnecting the USB cable). Set parameters as shown in the figure above. Prepare data to be transferred. Capture the waveform you need and put DSO112A in HOLD state so that the captured data will not change.

1Hz, 10Hz, 100Hz, 1KHz, 10KHz, 100KHz, 1MHz, and 440Hz. To select different frequency enter Menu and touch the “Test Sig.” button. The Test Signal Frequency screen shows. Select the frequency wanted and touch “Done” button to finish. JYE Tech - 16 - www.jyetech.com... -
Page 17: Δt Cursors
Never. If there is no screen touch activity detected within the time period the oscilloscope will shut down itself. However, if external power supply (USB) is used the auto power-off timing is disabled. The unit will never shut down itself in this case. JYE Tech - 17 - www.jyetech.com... -
Page 18: Serial Interface (Si)
The USB connection is based on a CP2102 Uart-USB bridge inside DSO112A. You need install driver for this bridge on PC if it is the first time to connect to DSO112A. Please go to Silicone Lab website to download the appropriate driver for your system and install it correctly. -
Page 19: Output Of Captured Data
Standalone Mode where captured data are displayed on LCD panel as waveform. In situation where captured data are wanted DSO112A can be set USB Scope Mode. Under USB Scope mode waveform display on panel will be disabled. All captured data are output through the SI. -

Page 32: Firmware Upgrade
Sometimes you might need to upgrade firmware to acquire new features or higher performance. There are two ways to change the firmware for DSO112A. One is by the pre-installed bootloader. The other is by a programmer. Upgrade Firmware by Bootloader Connect DSO112A oscilloscope to an USB port on PC. - Page 33 “Maximum connection count” to 100. This will make connection easier. Change settings on tab “Com Port”. Com port number should be chosen to the one corresponding to DSO112A. Communication format must be set to 9600 bps, 8N1, no parity and flow control. Then click OK button.
- Page 34 There are many such programmer available on the market (for example, sku# 07302 from JYE Tech). It is important to make sure that the connection between programmer and J3 on DSO112A is correct. The table below describes the signal names on J3. J3 Pin-out Description...
