Using P-Series Power Sensor

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 zero and calibration, this process is described in
Calibrating the P-Series Sensor"
The power meter and P-Series wideband power sensor continuously sample the
RF signal at a 100 mega-samples per second. Similarly, the dual channel meter
samples both channels at the same rate.
The instantaneous power of an RF signal can be detected with up to 30 MHz of
video
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.
Maximum dynamic range is related to the maximum sensor band width. Refer to
NOTE
the documentation supplied with your P-Series wideband power sensor for
specification information.
