function Oscope = ReadOscope(Lookup)
    % Oscope()
    %   Collect data created from Tektronix TDS 2014C Four Channel Digital Storage Oscilloscope
    %   Created by: jsl5865
    % Syntax:
    %   Oscope = ReadOscope(Lookup)
    % Description:
    %   Data collection from Tektronix TDS 2014C oscilloscope is standardized, therefore all recordings output the same 
    %       data structure. This function reads all of the oscilloscopes parameters and recorded data from the .csv file(s)
    %       produced after saving a waveform.
    %   This oscilloscope has four channels, which each produce a single .csv file when waveforms are saved (i.e. one .csv file
    %       for each channel). This script saves the Time & Voltage for each of these channels within arrays to be accessed later.
    % Input: 
    %   Lookup - structure created from FileLookup.m
    %          - File extension must be .csv
    %          - Only necessessary arguments: 
    %               - Lookup.FileCount : Total number of files
    %               - Lookup.FolderInfo.name : Name of files
    %               - Lookup.FolderInfo.folder : Folder(s) that contain files
    % Output:
    %   Oscope.{Oscilloscope Recording settings, Time, Voltage}
