38 * This is a unified protocol driver for the DS1000 and DS2000 series.
40 * DS1000 support tested with a Rigol DS1102D.
42 * DS2000 support tested with a Rigol DS2072 using firmware version 01.01.00.02.
44 * The Rigol DS2000 series scopes try to adhere to the IEEE 488.2 (I think)
45 * standard. If you want to read it - it costs real money...
47 * Every response from the scope has a linefeed appended because the
48 * standard says so. In principle this could be ignored because sending the
49 * next command clears the output queue of the scope. This driver tries to
50 * avoid doing that because it may cause an error being generated inside the
51 * scope and who knows what bugs the firmware has WRT this.
53 * Waveform data is transferred in a format called "arbitrary block program
54 * data" specified in IEEE 488.2. See Agilents programming manuals for their
55 * 2000/3000 series scopes for a nice description.
57 * Each data block from the scope has a header, e.g. "#900000001400".
58 * The '#' marks the start of a block.
59 * Next is one ASCII decimal digit between 1 and 9, this gives the number of
60 * ASCII decimal digits following.
61 * Last are the ASCII decimal digits giving the number of bytes (not
62 * samples!) in the block.
64 * After this header as many data bytes as indicated follow.
66 * Each data block has a trailing linefeed too.
