Rohde & Schwarz NRP-Z56 and NRP-Z57 thermal power sensors

Click2Contact

Rohde & Schwarz has expanded its range of power sensors by adding two models to the NRP family.

The sensors are the first to measure thermal power from DC up to 50 GHz and 67 GHz respectively. They are also the only thermal power sensors that can be used even without a base unit.

Connection to a PC takes place via USB. In addition to saving cost and space, the sensors offer good performance for calibration labs as well as for manufacturers of microwave transmission systems and RF/microwave components. A standing wave ratio (SWR) of 1.35 is achieved from 50 to 67 GHz. This is so far unparalleled and results in high precision. Linearity surpasses that of commercial products by a factor of 10 across the entire frequency range and allows accurate relative power measurements.

The NRP-Z56 and NRP-Z57 thermal power sensors (up to 50 and 67 GHz) offer good measurement accuracy. Sensitivity has been improved by minimising zero drift and noise.

The resulting increase in dynamic range (55 dB) enables thermal power measurements for powers as low as -35 dBm. In addition, measurement speed exceeds that of conventional instruments by a factor of three.

The company has developed a connector that incorporates a ball bearing, which simplifies correct attachment of the sensor to the DUT and provides a solution that also enhances measurement reproducibility.
