Dataq Advanced CODAS Analysis Software

Advanced CODAS offers sophisticated analysis functions not available in WinDaq Waveform Browser playback and analysis software. Beginning with acquired waveforms, Advanced CODAS creates calculated channels without ever leaving the WWB environment. The calculating 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.

 

Disk Streamer Performance

Generates calculated channels of any length limited only by the size of your hard drive.

 

Insert and Overwrite Modes

Advanced CODAS allows calculated waveforms to overwrite or append themselves to existing channels.

 

Menus or Batch Files

A single keystroke from the WWB screen activates the Advanced CODAS menu system of easy-to-use scripts. Simply enter calculation parameters, and activate the function. Often-used scripts may be combined into a batch file.

 

7 Calculation Functions

Advanced CODAS consists of seven functions: differentiator, integrator, moving average filter, arithmetic operations utility, peak and valley detector, and reort generator.

 

Differentiator

Calculates a rate of change waveform with built-in, adjustable low pass filtering.

 

Integrator with Four Reset Methods

Generates the area bounded by the curve reset on zero crossing of the input waveform, by the level of the output waveform, by time, and as a function of an external event.

 

Rectifier

Used in the analysis of polarized signals, this function produces a rectified view of any waveform. Supported rectification functions are absolute value (full wave), and positive and negative unipolar (half wave).

 

Moving Average Filter

Also referred to as a boxcar integrator, this utility can be used for filtering noise, or for generating mean waveforms. The function can also simulate a high pass filter to eliminate base line shifting.

 

Arithmetic Operations

This function allows you to combine waveforms as a function of arbitrary mathematical formulas. Also supports phase shifting of selected waveforms in precise increments.

 

Peak and Valley Detector

Detects cycle-by-cycle inflection points (minimum and miximum excursion) on any periodic waveform. Allows peak-only, valley-only, and peak and valley selections.

 

Report Generator

Generates a report of peak detected waveforms in spreadsheet (CSV) or ASYST/ASYSTANT format. Reports value at peak, value at valley, rate, and mean. Rate information may be reported in Hz, cycles per minute, or an interval in seconds. Reports value cycle-by-cycle, or on a multiple cycle averaging basis.
