Measurement considerations

While autoranging is a good starting point, it is not ideal for all measurements.
Signal conditions such as crest factor or duty cycle may cause the power meter to
select a range which is not the optimum configuration for your specific
measurement needs. Signals with average power levels close to the range switch
point require you to consider your needs for measurement accuracy and speed.
For example, using an E9300/1/4A sensor, where the range switch point is –10 ±
0.5 dBm in a pulsed signal configured as follows:

The calculated average power is –12 dBm.
