Advanced CODAS Analysis Software

Description

Advanced CODAS offers sophisticated analysis functions not available in WinDaq Waveform Browser playback software. Beginning with acquired waveforms, Advanced CODAS creates calculated channels without ever leaving the WinDaq Waveform Browser environment. The calculation functions, used individually or in any combination, may be applied to any waveform with fully automatic calibration in any desired unit of measure. Calculated channels are cleanly inserted into the waveform file and assume the characteristics of an acquired channel.
