result and the new measurement. The last result is weighted by (n – 1)/n. The
new result is weighted by 1/n. Each new measurement produces a new result.
If you are measuring an intermittent signal and no valid demodulated signal is
acquired, the numeric results will display the last valid, Running Average results
until a fresh, valid signal is acquired. This enables you inspect the averaged
results for poor quality, intermittent signals that might otherwise be lost.
• Max Hold: Is not an average, but on a point by point basis, displays the
maximum amplitude for the given frequency or channel since Max Hold was
turned on. It is updated when a new maximum occurs.
If you are measuring an intermittent signal and no valid demodulated signal is
acquired, the numeric results will display the last valid, averaged Max Hold
results until a fresh, valid signal is acquired.
• Group Average: Makes the requested number of measurements, averages the
measurement data, and displays the average as a single result-trace.
Measurement time will vary based on the requested number of averages and can
take minutes for very large number of averages.
• Group Max Average: Makes the requested number of measurements before
returning a single result-trace. This trace is the maximum value seen at each
trace point over the requested number of averages (measurements).
To set averaging:
