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.
