Power Sensor Characteristics

The power sensor has three primary functions. First the sensor converts the incident

RF or microwave power to an equivalent voltage that can be processed by the power

meter. The sensor must also present to the incident power an impedance which is

closely matched to the transmission system. Finally, the sensor must introduce the

smallest drift and noise possible so as not to disturb the measurement.

Table 2-1 lists the characteristics of the latest line of Continuous Wave (CW) sensors

offered by Boonton. The latest Peak Power sensor characteristics are outlined in Table

2-2. This data should be referenced for all new system requirements.
