E CH_(D)/(A+B)/(A-B)/(C&D)/(C|D)/
REC_A/ REC_B/ REC_C/ REC_D
thru CH_D: Input(A+B), waveforms of CH_A & CH_B sync
(A-B): get subtraction of waveforms of CH_A & CHA_B
(C&D): get and operation of CH_C & CH_D
(C|D): get or operation of CH_C & CH_D
REC_A: reload the last waveform saved in CH_A
Same for REC_B, REC_C & REC_D
