Add flag in config for sweep mode
#define FREQ_MODE_START_STOP 0x0 #define FREQ_MODE_CENTER_SPAN 0x1 Now sweep mode not defined from frequency0 > frequency1 or frequency0 < frequency1 frequency0 always < frequency1 All freq must get by use get_sweep_frequency(mode) Revert Select CH0 reflect channel before set freq, add additional delay on 0 sweep point
