SainSmart DDS140 Portable Handheld PC-Based USB Digital Oscilloscope 40MHz Bandwidth 200MS/s (DDS-140 + Signal Generator)

SainSmart DDS140 can be extended to achieve oscilloscope, signal generator and logic analyzer triple main functions by inserting different sub-modules. The advantages are the optional modular structure and high performance price ratio. Its body takes operation of traditional oscilloscope and part function of display transfer drawing into the computer by the software to achieve. As long as the device is via USB cable into your compute, it will form a complete oscilloscope test system.
