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.
ols supported The file format used by the "Alternative" Java client for the Openbench Logic Sniffer.
srzip supported supported The current (v2) sigrok session file format (*.sr).
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.

Supported transform modules

Name Description
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.
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.
