Rohde & Schwarz NRP-Z11
Average Power Sensor
Description
This unit fuse multiple path architecture, multiple diode technology and a simultaneously scanning multichannel measurement system into a unique high performance concept.
Multiple path architecture means combining two or three diode detectors to obtain a large dynamic range for modulated signals.
This is achieved by operating each detector exclusively in the square law region, and only using the optimally driven detectors for the measurement.
Multiple diodes comprise several zero bias Schottky diodes connected in series and integrated on one chip.
Key Points
6dB wide overlap ranges, smooth transitions
Simultaneous scanning and analysis
Chopper stabilization of the signal paths for repetitive signals
High signal/noise ratio throughout
Low modulation effect,
Negligible delays and discontinuities when switching signal paths,
Ability to perform a time-domain analysis of the test signal within the available video bandwidth.
Larger dynamic range
Specifications
Frequency range: 10MHz to 8GHz
