The CRC-16 that Rigol uses in the DG5000 is a "customized" CRC-16 with the following parameters:
width=16 poly=0xA011 init=0x1008 refin=false refout=false xorout=0x0000 check=0xAC1A residue=0x0000 name="CRC-16/RIGOL 1"
The CRC-16 that Rigol uses in the DG4000 is a "customized" CRC-16 with the following parameters:
width=16 poly=0xA011 init=0x0528 refin=false refout=false xorout=0x0000 check=0x147D residue=0x0000 name="CRC-16/RIGOL 3"
The CRC-16 that Rigol uses in the DG1000 is a "customized" CRC-16 with the following parameters:
width=16 poly=0xA011 init=0xFFFF refin=false refout=false xorout=0x0000 check=0x5CC1 residue=0x0000 name="CRC-16/RIGOL 4"
Many Rigol equipments use this variation:
width=16 poly=0x1021 init=0xEBCC refin=false refout=false xorout=0x0000 check=0x6809 residue=0x0000 name="CRC-16/RIGOL 2"
And, other Rigol equipments (that include a CRC-16), use the more common:
width=16 poly=0x1021 init=0xFFFF refin=false refout=false xorout=0x0000 check=0x29b1 residue=0x0000 name="CRC-16/CCITT-FALSE"
Edit1: Included a parsing of many Rigol file types (showing the CRCs).
Edit2: Added Rigol 2 CRC16 type.
Edit3: Added Rigol 3 and 4 CRC16 types.

How did you get those specs for the CRCs? Is there software you can run that takes as input a known piece of text and its CRC value, and can output the parameters needed to generate that CRC value from the known text?

I have my own tool but a good inspiration is here.

Hello. Do you have such a utility for working with ds1102z-e?
