Low cost two-path diode power sensors offer 80 dB dynamic range in production measurements
Power measurements over a dynamic range of 80 dB (-60 dBm to +20 dBm) are now possible for both CW and modulated signals. The noise component is two times less than that of comparable solutions on the market. As a result, measurement speed is increased by a factor of four.
The sensors are based on the proven and patented multipath technology from Rohde & Schwarz. The overlapping diode paths are measured in parallel. They are weighted in the transition range to ensure a smooth transition between measurement paths and eliminate differential nonlinearity. In addition, the user does not have to switch paths, since both diode paths are measured in parallel. This increases measurement accuracy and reduces measurement times.
The power sensors can be operated on the NRP2 base unit and on virtually all signal generators, spectrum analyzers and network analyzers from Rohde & Schwarz. Moreover, in combination with the NRP-Z4 USB adapter, the sensors can be used directly with a PC.
