Detailed Review:

Hi Guys,

 

After a customs clearance and holiday delays finally the OpenScope MZ arrived as a new year gift.

Along with the launch of our new YouTube Channel, here is my first review of the year.

Well actually after a long I was impressed with a USB Scope.

Its a small PCB loaded with

  • Oscilloscope
  • Waveform Generator
  • Logic Analyzer
  • GPIOs
  • Programmable Power Supply
  • Wifi Connectivity
  • SD Card Slot

 

 

Specification:

 

Connectivity

  • Wifi (802.11g)   (2.4 GHz only)
  • USB

 

Oscilloscope

  • 2 Channel
  • 12 bit Resolution
  • 2 MHz Bandwidth
  • Input Impedance of 1MΩ
  • ±20V  Voltage Range
  • 6.25 MSPS Sampling Rate
  • Input Impedance of 1MΩ
  • Buffer Size of 32640 Samples per channel

 

Function Generator

  • 1 Channel
  • 10 bit Resolution
  • 1 MHz Bandwidth
  • 3Vpp with ±1.5V offset Voltage Range
  • Maximum  Current 15 mA approx. (Digilent mentions 20mA)

Logic Analyzer

  • 10 Channels
  • 3V3 Logic Level
  • 10 MSPS Sampling Rate

 

GPIO

  • 10 Channels
  • 3V3 Logic Level
  • 7mA and 12 Source and Sinking Current

 

Programmable Power Supply

  • 2 Channels
  • ±4v Output Voltage
  • Maximum 50 mA/channel

 

The board requires a 5V power Supply, running on PIC32MZ2048EFG. and Wifi Module from PIC itself(MRF24WG0MA)

In case you guys want see only the "Scope in Action" part, did some Harmonic Analysis and Frequency Response Curves.

CONs

  • They could have provided with a little higher bandwidth
  • Buggy Wifi
  • Waveform Generator has to be stopped every time to adjust the parameters, this will be little tedious if  you are trying to fine tune things.
  • No Pattern Generator
  • No Protocol Analyzer
  • Non Responsive UI

 

PROs

  • Good  Accuracy and Sensitivity
  • USB and WiFi
  • Very good WiFi Range
  • SD Slot
  • Nice UI, I  loved  the one click button that pop up the pinout
  • FFT and Bode Plot Functionality
  • Can be programmed with Arduino or MPLAB X IDE.
  • Very good Documentation and an Archive of Video Tutorials
  • No need for any Apps on Mobile (I'm using a Windows Mobile so it  matters)
  • Open Source

 

Cheers
