The Rigol DS1000 series are 50-150MHz, 1GSa/s, 2-channel digital storage oscilloscopes. The 'D' suffixed models also include a 16 channel logic analyzer.
The bandwidth limitations appear to be software-imposed, and devices can be "upgraded" to a model number with a higher bandwidth by changing a firmware setting using undocumented commands in the protocol.
All variants currently appear to have the same USB VID and PID (1ab1:0588).

Protocol
All devices in the series support both USBTMC and RS232 connections. The same SCPI protocol is used over both connections. The serial parameters are 8n1, with baud rate from 9600 to 38400 (configurable in Utility/IO Setting menu on the scope).
