Rohde & Schwarz introduces the world's first USB-capable wideband power sensors that can measure up to 40 GHz

The wideband power sensors can be operated from a PC via the R&S NRP-Z4 USB adapter, or in combination with an R&S NRP/NRP2 power meter. They can also be connected to any signal generator or virtually any signal, spectrum and network analyzer from Rohde & Schwarz. Users can read the power measured from the DUT directly at the generator or analyzer. A complete measurement solution comprising an R&S NRP-Z85 or -Z86 and an R&S NRP-Z4 USB adapter is significantly more cost-effective than a conventional setup involving a power sensor and a power meter.

With a video bandwidth of up to 30 MHz and a sampling rate of 80 MHz, the R&S NRP-Z85 and -Z86 are the ideal choice for analyzing the time characteristics of modulated signals. The rise time of less than 13 ns enables easy measurement of the most frequently analyzed pulse shapes. The power sensors can measure both peak power and average power over a defined time interval as well as perform statistical signal analysis (CCDF, PDF). Their performance is far superior to that of commercial wideband power sensors: With a measurement uncertainty of 0.18 dB at 40 GHz, the new sensors offer unparalleled accuracy for continuous-average measurements. This combines with the sensors’ other exceptional performance features to make them the market benchmark in peak power applications.

The power sensors’ automatic pulse analysis function provides peak power and average power measurements as well as detailed information on other important power and time characteristics of pulsed signals. These include, for example, pulse top level, pulse duration, pulse period, pulse duty cycle and pulse rise and fall times. Using equivalent time sampling, the R&S NRP-Z85 and -Z86 can display pulsed signals with a very high time resolution. This is done by sampling a series of consecutive waveforms of a pulsed signal. The measurements are time-shifted relative to one another, yielding a compacted sequence of samples, which over time are combined into a complete waveform.
