Revision as of 21:08, 3 April 2016
The SainSmart DDS140 is a USB-based, 2-channel oscilloscope with an analog bandwidth of 40MS/s and 200MS/s sampling rate.
Optionally, it also supports usage as signal generator or logic analyzer.
See SainSmart DDS140/Info for more details (such as lsusb -v output) about the device.
