## Command Syntax

    :CHANnelN:THReshold:RFALl:TRACking  {{ON | 1} | {OFF | 0}}

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is `CHANnel4_2`.
