ARM DSO 203 Nano Pocket-Sized Digital Oscilloscope
 (Black Metal case - not easy to break)


(Please note: there are similar products in the market that come w/ black plastic case which is not good as metal case.)

 

Description

  This pocket oscilloscope is primarily used for applications in the following situations:
   1. Repair common electronic equipment  outside (Air conditioning or Industrial frequency inverter power supply, AC / DC switching power supply or inverter, elevator and building fire safety equipment, industrial control circuit)
   2. Hardware maintenance or software debugging RS232, RS485, I2C, CAN and other communications interface circuits, LED display and keyboard scan driver circuit, brushless motor drive circuit
   3. Audio equipment and circuits, electronic toys and remote control models, car repair electronic circuits
   4. School after-school teaching practice and student development of electronic small production
   5. Need to slow signal changes observed applications (such as: relay and switch contacts jitter, battery charge and discharge curves of the load transient response power supply, temperature sensor features measurement)
   6. The related supply t electronic circuit (SCR voltage regulator, power factor correction, electronic energy saving lamps, dysprosium lamp mercury lamp sodium lamp xenon lights drive circuit), As for other issues such as: CPU clock, RAM access, bus and USB or Ethernet signal measurement, high frequency and the video circuitry and the need to use FFT for signal analysis and so on occasion, The oscilloscope valued less than $1000 are not necessarily qualified for these. We advice to buy high-end oscilloscope! Deserves special mention is this pocket-sized internal battery-powered oscilloscope can be used, so in the field measurement, Ground is completely suspended, can be completely the same as multimeters, which measure what point, do not consider the issue of ground isolation.

Important Note:
Because this is a new products, the description may have some mistake, welcome to point it.

Cautions
The warnings and wrong operations possible cause dangerous.

Description:
►3" 240 × 400 widescreen color TFT LCD screen, STM32 is the master MCU, with the FPGA to implement the control and management of external ADC and data cache.
►At the same time to reduce the size and easy to DIY manual welding, MCU and the FPGA are selected QFP100 package, ADC selected QFP48 package.
►36M+36M sampling frequency, the use of the ADC AD9288-40 chip, single-channel maximum sampling frequency of the 72M.
►FIFO RAM has a maximum operating frequency of use of> 200MHz low-power FPGA to achieve.
►The AD9288-40 Overclocking to achieve 72M+72M sampling frequency, so that the maximum single-channel sampling rate up to 144M.
►Analog channel circuit using unity gain> 150MHz op amp, so the actual 30MHz analog bandwidth is expected to do more.
►As low power, low-cost, QFP package and other conditions of the FPGA, storage capacity is not large, so DSO203 sampling depth of the current situation for the multi-channel 4096 points per channel, single-channel work cases, 8192 points.

PACKAGE INCLUDES:

1 x DS-203 oscilloscope (with assembled case)

1 x 1000mah lithium battery

2 x Probe

1 x USB cable

A Flannel Bag is supplied for this item freely.


Frequently Asked Questions

Q: If this is a beta run, will the device be firmware upgradeable (via USB) when and if bugs are found?   
A: Sure, just copy the firmware onto internal USB disk, press ">" while booting up to upgrade.

Q: What are the user applications?     
A: [No official answer] As far as I know, there will be the possibility to boot up different applications that you can store on the U-Disk. I'll add a section to this page collecting ideas for user applications.

Q: What is the battery life? 
A: It's 1000mAH, 3.7V
