Binary

Raw, binary output format without any metadata. In the example below every byte contains one sample consisting of 8 probe values (each bit denotes the high or low value of one probe; bit 0 corresponds to probe 0, and so on). In the example, probe 6 is tied to GND (i.e., low), all others are high.

$ sigrok-cli --samples 1000 -f binary > somefile.dat
$ hexdump -Cv somefile.dat
