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
U2000/1/4A sensor, where the range switch point is –10 ± 1 dBm in a
pulsed signal configured as follows:
The calculated average power is –12 dBm.
