I have reversed the Rigol MSO5000 Waveform *.bin file format

Example export on USB key all channels on Rigol MSO5000 with following steps

1. Storage=>Save Wave
2. Connect an USB Key and choose the "Removable USB Disk (D)" (else by default it will be in "Local Disk (C)")
3. Format *.bin
4. Channel (choose all channels it also work for LA channels even if there is some strange bugs sometimes)
5. Save
   Then you have a *.bin file in your USB Key

To parse this bin file see https://github.com/bvernoux/rigol_mso5000/tree/main/waveform_bin which include some examples and 010 Editor Template to parse the Rigol MSO5000 Waveform *.bin file format
Note:
The 010 Editor parser template v0.2 is also compatible with Agilent Oscilloscope Waveform *.bin file format only the signature change AG instead of RG for the 2 first bytes
Thanks to miek for the link on Keysight website which use same bin format as Rigol MSO5000
