Optimizing the Readings

This section provides information on how to get the fastest readings from the MA24103A and MA24105A 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: MA24103A (<100 MHz) Averaging Table (Forward Average Power) and Table: MA24103 (>100 MHz) and MA24105A Averaging Table (Forward Average Power) describe the number of averages needed to attain a certain noise level for a particular power level measurement when measuring forward average power.
