Description

Advanced CODAS Analysis Software add-on to WinDaq Recording & Playback software.
Provides sophisticated analysis functions not available in the standard WinDaq software.

Allows calculated channels, derivative, integration, moving average, automatic file management, automatic scaling, and more.

 

Example of Advanced CODAS Analysis Software Usage

The Waveforms displayed in windows 1 and 3 are the Advanced CODAS inputs. Advanced CODAS applied the desired analysis, calculates the resulting waveforms, and outputs the results in windows 2 and 4.

 

Product Features

  • 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 Playback 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
    Differentiator, Integrator, Rectifier, Moving Average Filter, Arithmetic Operations Utility, Peak and Valley Detector, and Report Generator. (see below for more details)

Calculation Functions

  • Differentiator
    Calculates a rate of change waveform with built-in, adjustable low pass filtering.
  • Integrator With 4 Reset Methods
    Generates the area bounded by the curve reset on zero crossing of the input waveform, level of the output waveform, time, or 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.) Use this utility 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 maximum 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 values cycle-by-cycle, or on a multiple cycle averaging basis.
