wavegen_424.m

%% wavegen_424.m    
% function initialises the ao424 awg using the "wavegen" command
% Inputs:
% site : 1..6
% nchan: 1..32
% loop : 0 = one-shot, 1 = forever
% soft_trigger : 0 = no-trigger, 1=trigger
%
% Assumes that channel data files have been uploaded previously using upload_ch
% Queues AWG data files to the AWG device
% device is ready to go on trigger
% optional trigger arg starts the process, but a more likely  scenario is
% to use the trigger on starting an adjacent ADC module
