5-1 Pulsed RF Power Operation

30 Power Sensor Manual

Although this manual discusses power sensors used with average responding power

meters, for rectangular pulsed RF signals, pulse power can be calculated from average

power if the duty cycle of the reoccurring pulse is known. The duty cycle can be found

by dividing the pulse width (T) by the period of the repetition frequency or by

multiplying the pulse width times the repetition frequency as shown in Figure 5-1.

This technique is valid for the entire dynamic range of Thermocouple Sensors and

allows very high pulse powers to be measured. For Diode Sensors, this technique is

valid only within the square-law region of the diodes.
