Sample files
Recordings to try before you open your own.
Synthetic files in the formats your instruments and software export, with their usual channel names, units and rates. Download one and drop it on the app. Your own files open the same way: they are read in your browser and never uploaded.
Hydrogen and fuel cells
Stack test stations: cell voltage monitors, load banks, gas supply and coolant loop.
Cell_037 60-cell PEM stack, 30-minute test
Polarization staircase to 1.6 A/cm² and a dynamic load. 60 cell voltages at 10 Hz, stack values at 100 Hz, flows, pressures, humidity and coolant. Cell 37 floods at high load and recovers at every anode purge.
Stack Voltage 10-cell short stack, polarization curve
Station-style text export with a preamble and a units row: current density, stack voltage, HFR, ten cells, temperatures, pressures, humidity and flows at 10 Hz.
E-motors, power electronics and CAN
Dyno and power-analyzer recordings, and vehicle bus logs decoded with a DBC.
I_U PMSM dyno, full-load sweep
500 to 12 000 rpm at 300 Nm then constant power, a hold and regen. Phase currents and DC link at 20 kHz; speed, torque, efficiency and winding temperatures at 100 Hz.
MotorSpeed Vehicle CAN log, five-minute drive
VCU torque request, inverter status and temperatures, BMS pack values and a multiplexed cell-voltage message. Open both files together; cell 07 sags under load.
Biosignals
High-density EMG, EEG and lab streaming recordings, with their annotations and markers.
EMG R3C5 HD-EMG, 8 × 8 grid on biceps
64 channels at 2048 Hz plus force, two isometric contractions at 30 % and 60 % MVC. Motor units propagate along the columns; R5C3 has a poor contact.
O1 EEG, 32 channels, resting state and oddball
500 Hz, four minutes: eyes open, eyes closed with posterior alpha, an auditory oddball with a P300 on targets, blinks and a jaw clench. 121 annotations.
C4 Motor imagery session, LSL recording
A 16-channel EEG stream and the stimulus program’s marker stream. The mu rhythm drops over the motor cortex opposite the cued hand.
Power quality and grid
Protection relay and disturbance recorder output.
IA 132 kV feeder, phase-A-to-ground fault
Three-phase voltages and currents at 12.8 kHz: 8 kA fault with DC offset, single-pole trip, open-pole period and auto-reclose at 700 ms, with pickup, trip and breaker status.
Lab DAQ and vibration
High-rate accelerometer data as DAQ software and MATLAB scripts save it.
Accel_GB_X Gearbox run-up at 25 kHz
600 to 4200 rpm: gear-mesh orders crossing a 1.6 kHz housing resonance, an outer-race bearing defect and a tacho, plus a 100 Hz group. Made for a spectrogram.
acc_point1 Impact-hammer modal test
Five hits on a plate at 25 kHz with three accelerometers; modes at 182, 547, 1310 and 2730 Hz. The fourth hit is a double hit.
