LabChart 8.1.16 (Win)

Windows changes

  • Fixed issue where using the FE2XX Series Bio-amp (Octal, Quad, Dual and Neuro amps) input Low pass filters with cutoff frequencies of 1 kHz or lower could introduce inter-channel delays of up to ~1.5 ms.
  • Fixed issue where the FE2XX Series Bio-amp bandwidth was lower than expected at sampling rates below 100 kS/s. This also affected sampling with slave devices when sampling from multiple devices into the same document, e.g. when sampling with two PowerLabs the slave device would have a lower bandwidth than the master device.
  • Fixed issue with the delay compensation for FE2XX Bio-amp inputs. The delay between a signal recorded via the Bio-amp input relative to that recorded by a PowerLab input is now less than +/- 10 µs for sample rates above 100 S/s, and less than +/- 1 sample period for all sampling rates, so long as the PowerLab input and Bio-amp input have the same input low pass filter settings (including the case where the input low pass filters are both off).
  • New PowerLab Red enabler improves the self-calibration of 15 and 26 series PowerLabs (i.e. offset calibration on startup).
