Cirrus Seismic Evaluation Changelog

What's new in Cirrus Seismic Evaluation 2.4

May 16, 2012
  • Add CDB5378 Rev C

New in Cirrus Seismic Evaluation 2.3 (May 16, 2012)

  • Add switch control for CRD5376

New in Cirrus Seismic Evaluation 2.2 (May 16, 2012)

  • Add FFT averaging
  • Add "Coefficient_Files" folder which contains examples files for loading FIR/IIR/TBS coefficient.
  • Fix a bug: GUI doesn't stop data capturing when an error occurs in the middle of data capturing. This bug exists only in the version 1.9 (1.9 never released).
  • When impulse TBS is chosen, TBS Gain value is automatically set to -20dB.
  • Fix a bug: Sometimes, Filter IC doesn't allow Micro to read registers. It needs to be checked as soon as the USB connection established.
  • Micro reads the version register in filter chip to see if SPI communication is OK. If not, report an error message.
  • GUI used to save the last captured data in time domain. However, now GUI needs to save averaged FFT data.
  • GUI is not able to redraw FFT with the time domain data. Version 2.2 saves averaged FFT data and is able to reload the data and redraw FFT image.

New in Cirrus Seismic Evaluation 1.8 (May 16, 2012)

  • In calculating S/N number, Noise = (total Noise Power- Distortion Power)*(total bin/ (Noise bin-Distortion bin)). However, (total bin/(Noise bin-Distortion bin)) part is defined as integer, it always returns 1. So, define the equation as double.
  • Add CDB5376 Rev C

New in Cirrus Seismic Evaluation 1.7 (May 16, 2012)

  • Bug fixes:
  • Firmware skips at least one sample even though skip sample=0
  • This causes error at 4K sampling rate with skip sample =0.
  • Fix GUI (V1.7) and firmware(V1.4) both to handle zero skip sample properly
  • New feature:
  • Sync pulse generated at the beginning of each capture activity.

New in Cirrus Seismic Evaluation 1.6 (May 16, 2012)

  • Fix a compatibility issue:
  • It is reported that reading a register doesn't work properly with some PCs.
  • There is garbage data left over after reading and it causes error in writing.
  • Fix: Clearing USB buffer before exiting the reading module.
  • Add CDB5378 Rev B board support
