The optical fiber quality detection light of the TNF1AST4 board shares the light source with the OSC channel. When the TNF1AST4 board is used for detection in the "advanced parameter mode" (), the OSC communication will be interrupted. At this time, only the fiber quality detection signal is sent, and the detection dynamic range is large.
