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
00000000  bf bf bf bf bf bf bf bf  bf bf bf bf bf bf bf bf  |................|

ChronoVu LA8

sigrok chronovu-la8 output format in the ChronoVu LA8 software

This is the file format understood by the ChronoVu LA8 software. The usual file name extension is .kdt.

$ sigrok-cli -d 0 --samples 1000 -f chronovu-la8 -o foo.kdt

Limitations:

  • The file size must be exactly 8388613 bytes (8 MB samples + 5 bytes metadata).
