PowerXpert™ Help : Using the MA24106A : Optimizing the Readings
 
Optimizing the Readings
This section presents information on how to get the fastest readings from the MA24106A power sensor when using the Anritsu PowerXpert application or operating under remote control (refer to Programming Commands for Power Master for specific remote programming command descriptions). Measurement speed depends greatly on the type of measurement, the power level, and stability of the signal. Stability of a measurement is influenced by noise and signal modulation. If high resolution is required, averaging must be increased.
Note 
The values in the following tables are typical and should be used as a reference only.
Table: MA24106A Averaging Table (Low Aperture Time, Default Mode) describes the number of averages needed to attain a certain noise level for a particular power level measurement with the Low Aperture Time mode setting.
