Input output formats

libsigrok supports a number of different input modules (a.k.a. file formats) and output modules, and has a generic API which allows easily adding more input/output modules.

Supported input/output formats

Name	Input	Output	Description
Analog	—	supported	Text output of analog data and types.
ASCII	—	supported	ASCII art.
Binary	supported	supported	Raw binary data output without any metadata attached.
Bits	—	supported	0/1 digits.
ChronoVu LA8	supported	supported	ChronoVu LA8 software file format (usually with .kdt file extension).
CSV	supported	supported	Comma-separated values (also usable for generating data and config files for gnuplot).
hex	—	supported	Hexadecimal digits.
Intronix Logicport LA1034	supported	—	Intronix Logicport LA1034 *.lpf files.
ols	—	supported	The file format used by the "Alternative" Java client for the Openbench Logic Sniffer.
saleae	supported	—	Files exported by the Saleae Logic application.
srzip	supported	supported	The current (v2) sigrok session file format (*.sr).
STF	—	—	"Sigma Test File". Native format of the Asix Sigma/Omega vendor software.
VCD	supported	supported	The Value Change Dump format (can also be visualized in gtkwave, for instance).
WAV	supported	supported	The waveform audio (WAV) file format.
Raw analog	supported	—	Analog signals without header (configurable sample size, format, and endianness).
Lauterbach Trace32	supported	—	The Lauterbach Trace32 logic analyzer data file format.
WaveDrom	—	supported	Digital timing diagrams in JSON syntax

Supported transform modules

nop	Do nothing.
scale	Scale analog values by a specified factor.
invert	Invert values.

Possible candidates for future input/output formats

Name	Description
Scanalogic	Used by the IKALOGIC Scanalogic-2 and IKALOGIC ScanaPLUS logic analyzers.
Rigol ROF	Used by the Rigol DP800 series power supplies.
Rigol RAF	Used by the Rigol DG1000Z, DG4000, and DG5000 series signal generators. See DG1000Z User Guide page 2-75, also this post at eevblog.
Rigol WFM	Used by the Rigol DS series oscilloscopes. See https://github.com/mabl/pyRigolWFM/blob/master/wfm.py
Rigol WFM4	Used by the Rigol DS4000 series oscilloscopes.
Vector MDF (v3.3) / ASAM MDF (v4.x)	Automotive industry standard format. Docs can be found here and here. Validator is here. Some code is here and here.
COMTRADE	File format used by devices in power engineering (e.g. protective relays, fault recorders). Can contain digital and analog data with constant or variable sample rate.
PWL	Trivial file format that can be used to define the signal of voltage/current sources in a SPICE simulation.
Tektronix WFM	Used by the Tektronix TDS series oscilloscopes. A parser for Matlab can be found here.
EVCD/IDX/FST/GHW	File formats generated by hardware simulation tools. See the GtkWave manual for some of them, and conversion utilities.
NI TDMS	File formats used by various National Instruments software like LabVIEW or DAQExpress.
IMC data format	File formats used by imc GmbH softwares. File format description can be found in the imc Software Shared Components documentation. (Registration required.)
