The new power meter generation with modern and intuitive user interface
 
The R&S®NRX simultaneously supports up to four R&S power sensors and displays the results clear on the flexible configurable screen. The user interface with the touch screen based operating concept simplifies the operation. In addition function keys on the front panel provide quick access to the most important functions.
 
Key facts:
 
- Intuitive operation with touch screen based GUI
- Supports up to four R&S®NRP and R&S®NRQ6 power sensors
- Supports all sensor-dependent measurement functions
- Optional high-precision CW and pulse mode reference source module
- Optional power reflection measurements with NRT-Zxx sensors
R&S®NRX versatile, User-friendly base:
 
The R&S®NRX simultaneously supports up to four power sensors of the R&S®NRP and R&S®NRQ family. Function keys on the front panel provide quick access to the mostimportant functions. Users can open the frequency setting menu or zero the connected sensors at the push of button.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 5" 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. The 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 crest factor) can be graphically displayed in the trace window. All R&S®NRP-Z8x wideband power sensors allow automatic pulse analysis. Up to 12 of 18 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®NRX provides three different remote interfaces for integration in automated test setups: Ethernet, USB and optionally GPIB (R&S®NRX-B8). A trigger input on the rear panel permits external triggering for synchronized power measurements.
 
Expandable to up to four measurement channels:
 
The R&S®NRX standard configuration includes one measurement channel.The base unit can be optionally expanded to two (R&S®NRX-K2, software option) or four (R&S®NRX-K2 and R&S®NRX-K4, software options) measurement channels.
 
Flexible sensor interfaces:
 
The R&S®NRX provides two sensor connectors on the front and optionally two additional sensor connectors on the rear (R&S®NRX-B4, hardware option). A USB 2.0 interface on the front and the rear provides further connectivity (USB power sensors, memory key, mouse or keyboard).
 
Power reflection measurements:
 
The R&S®NRX optionally provides the R&S®NRX-B9 interface for the R&S®NRT2 directional power sensors.
 
Code emulation of the R&S®NRP2:
 
The R&S®NRX can interpret the command set of its predecessor, the R&S®NRP2.
 
Sensor check source:
 
An optional high-precision 50 MHz/1 GHz reference source module (R&S®NRX-B1 sensor check source) can be used in CW mode to check the function of all R&S®NRP power sensors. In pulse mode, the test generator can be used to check the pulse measurement performance of the R&S®NRP-Z8x wideband power sensors or the R&S®NRQ frequency selective power sensor.
 
 
 
Specifications with limits:
 
Represent warranted product performance by means of a range of values for the specified parameter. These specifications are marked with limiting symbols such as <, ≤, >, ≥, ±, or descriptions such as maximum, limit of, minimum. Compliance is ensured by testing or is derived from the design. Test limits are narrowed by guard bands to take into account measurement uncertainties, drift and aging, if applicable.
 
Specifications without limits:
 
Represent warranted product performance for the specified parameter. These specifications are not specially marked and represent values with no or negligible deviations from the given value (e.g. dimensions or resolution of a setting parameter). Compliance is ensured by design.
 
Typical values (typ.)
 
Characterizes product performance by means of representative information for the given parameter. When marked with <, > or as arange, it represents the performance met by approximately 80 % of the instruments at production time. Otherwise, it represents the mean value.
 
Nominal values (nom.)
 
Characterize product performance by means of a representative value for the given parameter (e.g. nominal impedance). In contrast to typical data, a statistical evaluation does not take place and the parameter is not tested during production.
 
Measured values (meas.)
 
Characterize expected product performance by means of measurement results gained from individual samples.
 
Uncertainties
 
Represent limits of measurement uncertainty for a given measurand. Uncertainty is defined with a coverage factor of 2 and has been calculated in line with the rules of the Guide to the Expression of Uncertainty in Measurement (GUM), taking into account environmental conditions, aging, wear and tear.
