Application Notes

Regular channel data is required for a number of IP applications, such as plotting pseudo-sections. The IPWINDOW GX creates a new channel from selected array channel columns.

Multiple Windows/Frequencies

For Time Domain array channels, multiple channels are summed using a weighted average based on the width of each time window. For Frequency domain channels, a simple summation of values is used.
