Noise suppression of SM 331; AI 8 x TC
The table below contains the frequency codes to be entered at byte 1 of data record 128
(see the previous figure.) The 400 Hz, 60 Hz and 50 Hz settings only apply to 8channel
software filter mode. The 50 Hz, 60 Hz and 400 Hz settings only apply to 4- and 8-channel
hardware filter mode.
