NRP2

The compact, robust R&S®NRP2 base unit with color display supports up to four R&S®NRP-Zxx power sensors and all sensor-dependent measurement functions. Measured values are displayed numerically or graphically, depending on the measurement function. The window-based user interface allows simple, intuitive operation; the base unit can be remotely controlled via Ethernet, GPIB or USB.

Features & Benefits
Straightforward numerical and graphical display of measured values, plus intuitive operation
The R&S®NRP2 simultaneously supports up to four power sensors of the R&S®NRP family. Function keys on the front panel provide quick access to the most important functions. Users can open the frequency setting menu or zero the connected sensors at the push of a button. The mode key provides direct access to all available measurement functions.

User-programmable save/recall memory locations allow fast access to personal settings. Presets for all major mobile radio standards, such as 3GPP LTE, 3GPP WCDMA, GSM/EDGE, WLAN and Bluetooth®, ensure correct measurement with a minimum of keystrokes.

The brilliant TFT color display supports the intuitive, window-based operating concept. Key parameters and functions are color-coded and can be seen at a glance.

Results are presented in numerical and graphical display windows that can be easily configured.

In the continuous average, burst average timeslot and time gate average measurement modes, up to four numerical results can be displayed in parallel. Ratio, SWR, return loss and reflection coefficient can be calculated from two measurement channels using predefined computation functions and displayed in addition to the absolute and relative power level.

Trace measurements and statistical measurements are presented in graphical windows. The trace mode allows simultaneous display of two traces in one measurement window. Level differences and time offset can be seen at a glance and accurately measured using horizontal and vertical markers. It is also possible to display the ratio of two traces.

Timeslots and time gates as well as the associated measurement values (average, peak or peak/average) can be graphically displayed in the trace window.

All R&S®NRP-Z8x wideband power sensors allow automatic pulse analysis. Up to six of 15 user-selected pulse parameters can be displayed in addition to the measurement trace.

The statistical amplitude distribution of the envelope power is shown as CCDF, CDF or PDF in a statistics window.

Hardware interfaces for remote control and triggering
The R&S®NRP2 provides three different remote interfaces for integration in automated test setups as standard: Ethernet, USB and GPIB.

A trigger input on the rear panel permits external triggering for synchronized power measurements. Using an R&S®NRP-Z81, for example, a trigger signal can be derived from the measurement signal and output at the trigger output (trigger master mode). A level-proportional voltage or a digital signal for limit monitoring can be output via BNC connectors.

Emulation of other common power meters
The R&S®NRP2 can interpret the command set of other power meters. Legacy instruments in existing systems can be quickly replaced by the R&S®NRP2 without additional programming effort. Instruments that can be emulated include the predecessor, the R&S®NRVD, and other manufacturers instruments:

• R&S®NRVD    
• HP 436A
• HP 437B
• HP 438A
• Agilent N1911A
• Agilent N1912A
• Agilent E4418B
• Agilent E4419B

Expandable to up to four measurement channels
The R&S®NRP2 standard configuration includes one measurement channel. The base unit can be optionally expanded to two (R&S®NRP-B2) or four (R&S®NRP-B2 and R&S®NRP-B5) measurement channels. An optionally integrated 50 MHz/1 mW reference source (R&S®NRP-B1 sensor check source) can be used to check the function of the power sensors.
