Descrição
The R&S®NRP-Z85 wideband power sensors are ideal for radar applications. In development or during installation and maintenance, pulse characteristics as well as output power have to be measured. Similar measurements are required in the production of radar systems and radar components. Thanks to a maximum video bandwidth of 30 MHz and a rise/fall time < 13 ns, the sensors can measure pulses with a pulse width as small as 50 ns.

Key pulse parameters are determined automatically to simplify the measurement and prevent operating errors. By increasing the sampling rate, the high-resolution mode for repetitive signals permits the display of strongly magnified signal sections with a high graphical resolution.

Key Facts
• Measurement range: -60 dBm to +20 dBm (1 nW to 100 mW)    
• Frequency range: 50 MHz to 40 GHz (50 MHz to 500 MHz with reduced video bandwidth)
• 2.92 connector
• Operation with R&S®NRP2 base unit or via USB on a Laptop/PC
• Ideal for radar applications
• 30 MHz video bandwidth
• Rise/fall time <13 ns
• > 9500 measurements/s (buffered mode)
• Automatic pulse analysis
• Statistical analysis
• High resolution mode
• Trigger master mode

Features & Benefits
Outstanding dynamic range and accuracy
The dynamic range of the R&S®NRP-Z8x wideband power sensors yields a lower limit of -47 dBm for envelope power measurements and -60 dBm for average power measurements. This sensitivity is unique and so far unprecedented on the market. With benefit from enhanced reproducibility and high measurement speed.

These sensors are therefore ideal for analyzing envelope power as well as for measuring average power.
R&S®NRP-Z85 Wideband Power Sensor Features & Benefits

High resolution mode
Some applications require the display of strongly magnified signal sections such as the rising edge of a pulse. To improve the graphical display in the trace mode, which has a resolution of 12.5 ns, a high density of samples is required. Equivalent time sampling with repetitive signals can achieve a time resolution of up to 100 ps.

Highest measurement speed
The R&S®NRP-Z8x wideband power sensors are the world is fastest sensors. In buffered mode, a specified measurement speed of > 9000 measurements/s can be achieved.

Automatic pulse analysis
Automatic pulse analysis supports operators in measuring important pulse parameters. It eliminates the need for complex measurements using markers; changes in the pulse shape are immediately taken into account in the measurement results.

The following parameters are determined by automatic pulse analysis:

• Time parameters: rise/fall time, start/stop time, pulse width, duty cycle, pulse period, pulse off time

• Level parameters: pulse top, pulse base, peak, average, minimum, overshoot (positive and negative)

Statistical analysis
The R&S®NRP-Z8x wideband power sensors permit statistical analysis of the amplitude distribution of noise-like signals to determine key parameters such as peak envelope power, average power and peak-to-average power ratio. The measurement data supports the design of components for modern OFDM or CDMA based wireless systems, such as EUTRA/LTE and 3GPP FDD. A measurement of the CCDF, CDF or PDF using one million samples can be performed by the R&S®NRP-Z8x wideband power sensors in less than 25 ms at full video bandwidth.

It is also possible to perform statistical analysis on an individually configured time gate so that only specific signal sections are observed.

Trigger master mode (with base unit or R&S®NRP-Z5)
Combined with the R&S®NRP2 base unit or the R&S®NRP-Z5 sensor hub, an R&S®NRP-Z8x wideband power sensor can be used as a trigger source. In the trigger master mode, a trigger signal is derived from the measured signal inside the power sensor and forwarded to the base unit or sensor hub for further use. All other connected sensors can be externally triggered using this trigger signal.

Supported Devices
The R&S®NRP-Z85 sensor can be connected to latest-generation of signal generators, spectrum analyzers and network analyzers. This allows you to directly display the average power measured with the sensor without the need for an R&S®NRP2 base unit or PC. This also provides a simple solution for automatic level correction in a signal generator. The spectrum analyzers use the measured power as an absolute reference for increasing the measurement accuracy.
