3 Using P-Series Power Sensor
108 Keysight N8262A User’s Guide
Introduction
The P-Series Wideband Power Sensor’s mode of operation is optimized to
measure the peak and average power of pulsed or modulated signals with a wide
bandwidth.
The power meter automatically recognizes a P-Series Wideband Power Sensor
when it is connected. The sensor’s calibration data, characterizing the sensor
output versus input power, frequency and temperature, is automatically read by
the power meter. After the sensor’s data is read, the power meter automatically
performs a zeroing and calibration, this process is described in “Zeroing and
Calibrating the P-Series Sensor” on page 92.
The power meter and/with P-Series Wideband Power Sensor continuously
samples the RF signal at 100 mega-samples per second.
The instantaneous power of an RF signal can be detected with up to 30 MHz of
video
[1]
bandwidth (modulation bandwidth).
The triggering methods used by the system (power meter and sensor) enable the
continuous measurement of modulated signals or single events. A trigger can be
taken from a rising or falling edge of an RF signal pulse or controlled externally.
[1] The term video is applied to a signal that has been amplitude demodulated from an RF carrier, but
contains components in the RF part of the spectrum. For a power meter it refers to the output of
the sensor diodes.
NOTE
Maximum dynamic range is related to the maximum sensor bandwidth. Refer to
the documentation supplied with your P-Series Wideband Power Sensor for
specification information.
