The overall performance of a power meter dependents on the power sensor employed. Boonton has a variety of quality power sensors to meet virtually all applications. Boonton has a complete line of Peak and Average power sensors up to 40 GHz for all of your fast rise time, wide bandwidth and wide dynamic range applications.

Boonton has a large variety of power sensors that are compatible with the 4540, 4500B, 4300, 4240 and 4530 series of Boonton power meters. The power meter specifications describe the instrument's warranted performance. These specifications are valid over the instrument's operational and environmental ranges after performing a zeroing/calibration procedure unless otherwise stated. Measurement uncertainty information can be found in the Boonton power sensor manual that is available upon request.

Functions of Power Sensors
The sensor converts the incident RF or microwave power to an equivalent voltage that can be processed by the power meter. Next, the sensor presents to the incident power impedance that is closely matched to the transmission system. Both must be done with minimal drift and noise for the most accurate measurements.

Calibration and Traceability
Boonton employs both a linearity calibration as well as a frequency response calibration. This maximizes the performance of Diode Sensors and corrects non-linearity on all ranges. Linearity calibration can be used to extend the operating range of a Diode Sensor. It can also be used to correct non-linearity throughout a Thermocouple or Diode sensor's dynamic range. Frequency calibration factors (NIST traceable) and other data are stored within all peak power sensors. Linearity calibration is performed using the peak power meter's built-in calibrator.

Sensor Selection
Boonton Diode Sensors are constructed using balanced diode detectors. This dual diode configuration offers increased sensitivity and harmonic suppression when compared to a single diode sensor. When choosing a power sensor, several factors must be considered including frequency range, dynamic range and modulation. The sensor should have a faster rise time than that of the modulated signal. Boonton offers various peak power sensors for a huge variety of frequency ranges allowing measurements with widest dynamic range and fastest rise times.
