DSO Quad also known as DSO203 is a pocket size 4 channel digital oscilloscope for common electronic engineering tasks. It's based on ARM cortex M3 (STM32F103VCT6), providing 72MS/s sampling rate with integrated FPGA and high speed ADC. An internal 2MB USB disk can be used to store waveform captures, user applications and to upgrade firmware.
Features
- Pocket size and light weight
- Two 36MS/s analog channels, Upto 72MS/s if configured to single channel.(Upgrade to Two 72MS/s analog channels, Upto 144MS/s if configured to single channel from .sys version v1.31)
- Two digital channels
- Signal Generator
- Various Triggering Option
- Easy waveform storage
- Firmware upgrade
- User applications
- Open source

Idea Collection
**Applications **
'Simple Mode' - where only the most basic functions are available to help people without experience.
- Detailed at https://github.com/PetteriAimonen/QuadPawn/wiki/Advanced-Volt-Meter
Protocol analysis/data capture - Serial, I2C, SPI, CAN
LCR (uH, uF and R) measurement capability - The inbuilt signal generator makes this a natural. Three methods exist, all requiring an external component(s) Example
Semiconductor Analyzer - Use the DAC to test and chart the voltage response of a diode / transistor (and simply identify components, such as transistor pinout and polarity)
RF spectrum analyzer
A 2D X-Y mode that plots the analog channels against each other on two axes with a digital channel optionally functioning as a 'beam' enable/disable.
- Something seems to exist? Not in APP2.50 yet.
A DMX Decoder/Analyser and generator (used in conjunction with an external RS485 IC) would make this a VERY useful gadget for theatre techs.
Television mode (analog TV) : Display frame/field/line (select field A/B) or line number. Display vectorscope diagram. Display content (ie: the TV image).
Synchronization with a second DSO Quad for a 4 channel analog/digital signal, perhaps similar USBscope50 [moved from HARDWARE]
use 'wave out' to generate a pulse/step when master unit triggers, use C/D as trigger for slave(s)
Create USB remote control software, such that if LCD breaks, you can still use it with PC software. [moved from HARDWARE]
Stream data to PC - Use PC as storage buffer, with additional processing power. A PC could decode I2C words and other protocols where the Quad wouldn't. [moved from HARDWARE]
White noise function - add to the functions generator
Enhancements
- A spectrum analyzer displaying a view from a frequency/time perspective
- Fast Fourier Transform, would be nice and easy for viewing spectrum data of a single signal.
Hardware/Device-Oriented
SDR (Software defined radio) note we only have USB full speed (12Mb/s)
Preamplifier 10x badly needed!!!
Add bezel buttons for easier to access menus.
Add 2 more analog channels, Perhaps via USB dongle.
Add port for expansion devices, such that and add-on device can offer more capabilities, like RF generation, or a function generator that is capable of larger amplitudes. In particular a +5v and 3.3v output would be useful.
Other
Service application for technical support staff. Could split the screen and display instructions like 'Check if port 3, pin 5 has a signal, if not xyz might be broken'. There could be a next button and for each step the text, the right timescale, trigger values etc. are selected
My phone is ARM based, perhaps make a USB version of this and an app for my phone, that allows my phone to be the display / insured touch screen display.
Simple math functions on both analog channels and generated signal.
Two totally ground separated input would enable measureing inputs, which are not the same ground referenced. (like in the Velleman two-channel personal scope)
Input overvoltage protection diode should be added to protect device form HV spikes
Oversampling and its software implementation could decrease noise, and increase effective bit depth
Special technique equivalent time sampling, could increase bandwidth for repetitive signals
Non-storage mode which constantly sweeps the visible area instead of storing into a huge offscreen buffer. I set the sample rate to 50ms in the current version (eg. to look at an audio signal) it only updates the screen once every few seconds, it should update continuously.
Please add more ideas..

Components
Please add links to core components (play/pause) button while turning on the device. Your device is now in firmware upgrade mode, and a USB disk should appear on your system. You copy the firmware files one at a time, and each time you copy a new file, the device will disconnect to prepare the file. When the disk reconnects, the extension of the file you uploaded will change ('.rdy' means the upload worked properly).
The order that you upload the files in DOES matter. Start by uploading the .hex files (order unimportant). To upload the .BIN files, you need to first upload the corresponding .ADR file. This tells the device where to put the binary file (e.g. upload CFG_FPGA.ADR first, then upload xxxxFPGA.BIN immediately after). If you make a mistake, delete all the files and start again.
When you're finished uploading all the firmware files, turn off the device to complete the upgrade. When you boot the device again, your firmware versions should be updated. If you get an error at the splash screen, try uploading the firmware again, carefully following the instructions above.
More details and Linux instructions here: DSO_Quad:Upgrading_Firmware
File Descriptions
| File Type | Filename Format | Description |
|---|---|---|
| FPGA File | xxxxFPGA.BIN | configuration data for the FPGA |
| Logo File | logo_xxx.BIN | Create any 16 color 64*256 .BMP file (filesize = 46.9KB), and change the extension to .INF. This is the image displayed on the splash screen. |
| System File | SYS_xxxx.hex | ??? (description needed) |
| Application File | APP_xxxx.hex | ??? (description needed) |
| Address File | xxxx.ADR | These files tell the device where to put the next .BIN file you upload. There is one for the FPGA file, and one for the LOGO file. The files are named so that you know which goes with which. |
note: as newer versions become available, these filenames may appear slightly different. The x's represent values that could change over time.
Memory layout
| Begin | End | Size | note |
| 0x00000 | 0x03fff | 16384 | DFU |

| 0x2c000 | 0x3d7ff | 71680 | FPGA bitstream (Datasheet says maximum size is 533KBit, so this is a bit large) |
| 0x3d800 | 0x3ffff | 10240 | Logo (bmp, 256x64, 4 bit) |
Note: The flash base address is 0x08000000, but is mirrored by the chip at 0x00000000 when BOOT0 is low.
