See SR setup using text-file commands (version 2.0 and later)
The main purpose of running source/receiver (SR) setup is to encode the proper distance and location information into the header of each channel's data in the recorded field files (records). This setup is usually encoded into original field records during the field operation by the acquisition software if the operator arranges necessary parameters properly at the beginning of data acquisition. This can be checked at the early stage of SR setup when importing field records of SEG-2 format (and, if they are confirmed to have the correct setup encoded, then they can be saved as a single file in the PS-format [*(SR).dat] ready for the regular MASW analysis and this separate setup procedure will be skipped). If the SR setup was ignored during data acquisition or the original setup is in error, then the correct setup can be encoded by running this "Source/Receiver (SR) Setup" module
The SR setup can also be applied to a previously saved file of PS-format from the main menu. In this case, only one file is selected for input. To select one file as illustrated below.
