Set up IP Time Windows or Frequencies

This is a right-mouse-button contextual GX for inspecting or updating the time or frequency windows of an IP array channel.

Setup IP Time Windows or Frequencies dialog options

Domain type

 Indicates if the data is time or frequency domain. This field is editable to allow you to input the information for older historical data.

Windows | Frequencies

 Number of time of frequency windows. This is set to the dimension of the array.

Delay time | Base frequency

For time domain IP, the time delay before the first reading. For frequency domain, the base frequency.

Time windows | Frequencies

Expanded or concise list of the time/frequency values. The concise syntax is n x m interpreted as values (m) repeated n times .

Application Notes

The IP menu loads this contextual right-mouse menu item which only applies to array channels. If the time or frequency window information is imbedded in the array channel it will be loaded. For older data, not containing this information; you can input it using the same tool.

This is an interactive tool only, and hence does not have scripting parameters.

The format for the time windows has been standardized with that for the voxel cell sizes in VOXSTAT.GX, with the existing addition that if you do not have the full number specified, the last value is assumed to be repeated as many times as necessary so that all array elements have an assigned time window value.

Variable Cell Size Syntax

n [x|X|*] m [[ ],] l [x|X|*]p [ ,] q

Where:

n & l represent the number of array elements

m & p are the value of the repeated element respectively n and l times

q is the last element value and if it is repeated, it is not necessary to enter the number of repetitions

The above sequence can be repeated as many times as necessary.

For example, for an array of 16 elements all of the following are acceptable:

  • 30 (indicates 16 elements of value 30)

  • 4x20 2x50,30 (indicates elements 0,1,2,3 have a value of 20, elements 4,5 have a value of 50, elements 6 to 15 have a value 30)

  • 4*20 2*50 30 (is interpreted as above)

  • 4X20 12*50 (indicates elements 0,1,2,3 have a value of 20, elements 4 to 15 have a value of 50)

  • 30, 4x20, 2x50,30 (indicates element 0 has a value of 30, elements 1,2,3,4 a value of 20, elements 5,6 a value of 50, followed by 9 elements of a value of 30)
