The Instrustar ISDS205X is a USB-based

• 2-channel oscilloscope with an analog bandwidth of 20MS/s and 48MS/s sampling rate,
• 2-channel "data recorder" (same as oscilloscope, simply storing the analog data),
• 2-channel spectrum analyzer with an analog bandwidth of 20MS/s,
• 1-channel DDS signal generator (sine, square, triangle, up sawtooth, down sawtooth); sine up to 20MHz, rest up to 2MHz,
• 8/16-channel logic analyzer with a max. sampling rate of 24MHz.

See Instrustar ISDS205X/Info for more details (such as lsusb -v output) on the device.
