Description
The TH command sets the minimum amplitude level and clips data at
this value. Default value is −90 dBm. See also MKPT. MKPT does not
clip data below its threshold.
NOTE When a trace is in max-hold mode, if the threshold is raised above any
of the trace data, the data below the threshold will be permanently lost.
