Press Mode key to select and add the expected mode to window management.
Press Meas Setup key to enter the corresponding measurement parameter configuration
menu. According to the actual needs, select the required parameter configuration options, obtain

Average|Hold times
Average|Hold Times N, is the counter when the trace type is "average", "max hold" and "min hold".
In a single measurement (Single), and any valid trace type is "average", "max hold" or "min hold",
the sweep stops when the counter reaches N.
Larger (average|hold) times can reduce the influence of noise or other random signals, thereby
highlighting stable signal characteristics in the signal.
