--- Quote from: tv84 on February 01, 2018, 10:14:36 pm ---A bit of OT but, for the record, may be useful to others who want to verify Rigol CRC's: 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. --- End quote --- 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? |
