Making Measurements Using the Power Sensor
3-14 PN: 10585-00016, Rev. A MA24104A UG
Table 3-1, 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.
Table 3-2, describes the number of averages needed to attain a certain noise level for a particular power level
measurement with the High Aperture Time mode setting.
Note: The values in the following tables are typical and should be used as a reference only.
