Description

Once we came across this piece of gear we knew that we had to stock it.  What is lacks in sample rate it makes up for in size and portability.  We find we use ours even more often than our desk scope as it is tremendously convenient.  

Scope traces can be dumped via USB to a PC using a UART-USB converter.  If you don't happen to have one on your bench we do have a low-cost version available.  The same converter doubles as a firmware programmer with a simple modification.

Specifications

• Footprints provided for user analog extend/experiments - users can quickly build their own analog circuits (amplifiers, filters, oscillators, etc) using two redundant on-board opamps. 
• Alternative power supply connector, LCD trimmer, and M64 programming header relocated to the bottom edge of board, where back panel has an opening for easy access.
• LCD contrast adjustable by trimmer - easily accommodate LCDs from different manufacturers
• Wider measurement range for the frequency meter -- up to 10MHz comparing to < 5MHz in existing models
• Precise voltage reference provided for accurate analog measurement
• Vertical sensitivity indicator
• Couple setting indicator
• Screen display is now complete where waveform captures need to be stored for later analysis. 
• Auto switching between Oscilloscope Mode and Frequency Meter Mode 
• Removed conflict between LCD and buttons
• Removed conflict between LCD mounting pins and 7805 heatsink 
• Test signal terminal relocated to the left side for quick connection 
• M64 programming header pin-out changed to STK200 compatible pin-out
