The Rocktech BM102 is a USB-based, 2-channel oscilloscope with an analog bandwidth of 20MS/s and 50MS/s sampling rate.
This device appears to be a rebadge of the SainSmart DDS120 (or vice versa). The lsusb is exactly the same, the PCB is exactly the same (both have a "656517" and "102LJT1402" silkscreen), and the components used appear to be the same as well.
The device was apparently created by someone named "buudai" in 2012 (also reflected in the lsusb and in the former buudai.com website).
See Rocktech BM102/Info for more details (such as lsusb -v output) about the device.
