Page 4 Supplement R&S NRP The data sheet specifies how long the R&S NRP can be operated from the battery. The battery operating time depends on the number and type of the connected sensors and especially on the brightness of the display backlighting. The battery can be charged at temperatures between 5°C and 30°C and discharged at temperatures ranging from 0°C to 40°C.
Page 5 R&S NRP Supplement (¶ MENU) The calibration cycle is performed. First of all, the battery is fully ä charged, then fully discharged and finally fully charged again. This process may take between 11 and 20 hours depending on the charge status of the battery at the beginning of the calibration cycle.
Page 6 R&S NRP Supplement Supplement to Operating Manual R&S NRP 1144.1400.12-04- Dear Customer, Your power meter is equipped with firmware version ≥ 03.00. A number of functions have been modified since the printing of the manual, and the modifications are described on the following pages. Ethernet For remote control via a TCP/IP-based LAN, the R&S NRP can be fitted with an optional 10/100BaseT Ethernet interface (option R&S NRP-B4).
Page 7 Supplement R&S NRP VXI11 The VXI11 protocol uses ONC RPC (open network computing remote procedure calls), making it possible to call R&S NRP functions at the source code level as if they were running locally on the controller. The following figure shows the relationships of the relevant protocol layers in the OSI reference model.
Page 8: Connection Setup
R&S NRP Supplement Communication channels of a VXI11 connection Channel Meaning Core All client-server communication, excluding aborts and interrupts, is handled via this channel. Abort Since the commands in the core channel are serialized and therefore cannot be interrupted, asynchronous abort commands must be transmitted via a separate, independent channel. This channel serves no further purpose.
Page 9 Supplement R&S NRP VXI11 protocol functions Function name Channel Meaning core Opens a link to a network instrument device, setting up socket connections for the create_link() core and abort channels, but not for the interrupt channel. destroy_link() core Cancels a link to a network instrument device. core Sends an IEEE 488.2 or SCPI command as a string to a network instrument device.
Page 10 R&S NRP Supplement If the R&S NRP is connected to a controller via a USB 1.1 interface, it logs on as a USBTMC (USB test and measurement class) device, provided that USB is selected as a remote interface in the System Remote menu.

Page 265 Remote Control - Commands R&S NRP Service Request, Use of the Hierarchical Structure Under certain conditions, the device may send a service request (SRQ) to the controller. This service request usually causes an interrupt at the controller to which the controller program can respond by suitable actions.
Page 266 R&S NRP Remote Control - Commands Parallel Poll In case of a parallel poll, up to eight devices are simultaneously requested by the controller to transmit one bit of information on the data line, i.e. to set the data line assigned to each device to logical 0 or 1. Analogously to the SRE register, which determines the conditions for generating an SRQ, a Parallel Poll Enable Register (PPE) is available which is ANDed bit-by-bit with the STB (taking into account bit 6).

Page 277 Remote Control - Commands R&S NRP SYSTem:STANdard:PRESet <string> The R&S NRP can be easily configured for measuring standardized signals (e.g. mobile radio standards). For this purpose, the standards listed in the Annex ( Standard Configurations) are stored in the R&S NRP. The SYST:STAN:PRES command sets the listed parameters and, if desired, also configures front-panel display windows (if SYST:STAN:PWS ON).
Page 278 R&S NRP Remote Control - Commands TRIGger The trigger commands are used to configure the timing conditions for the start of a measurement. Note: When the sensors are connected to the R&S NRP, they inform the device about the SENSe and TRIGger commands supported and about the value ranges for parameters.
Page 279 Remote Control - Commands R&S NRP INITiate[1..4|:ALL]:DISable[?] ON | OFF This command prevents the execution of the INIT:IMM command for one or more sensors. It can thus suppress the start of a measurement for specific sensors if the INIT:ALL:IMM command is used. *RST value: OFF INITiate[1..4|:ALL][:IMMediate][?] This command starts a single-shot measurement.

Page 281 Remote Control - Commands R&S NRP TRIGger[1..4|:ALL][:IMMediate] Performs triggering and ensures that the sensor directly changes from the WAIT_FOR_TRG state to the MEASURING state irrespective of the selected trigger source ( ). A trigger delay set with TRIG:SOUR TRIG:DEL is ignored but not the automatic delay determined when TRIG:DEL:AUTO:ON is set. When the trigger source is HOLD, a measurement can only be started with TRIG.
Page 282 R&S NRP Remote Control - Commands TRIGger[1..4|:ALL]:SOURce[?] BUS | EXTernal | HOLD | IMMediate | INTernal Sets the trigger signal source for the WAIT_FOR_TRG state. The trigger event is initiated by TRIG:IMM or *TRG. In this case, the other trigger setting are meaningless.

Page 320: I Programming Measurements With The R&S Nrp
R&S NRP Annex: Remote Control - Commands Programming Measurements with the R&S NRP Measuring with high-level commands The R&S NRP is based on the instrument model defined in the SCPI 1999.0 standard. This model provides a number of logic blocks that can be configured via remote-control commands. The R&S NRP is provided with high-level measurement commands that automatically perform the most important settings and simplify measurements, thus making it unnecessary to completely configure these blocks for each measurement.
Page 321: Relative Measurements
Annex: Remote Control - Commands R&S NRP Relative measurements If the measurement results are to be output not as absolute values, but relative to a reference value, the keyword :RELative can be added to the measurement command. The result is then divided by a value that was previously set by means of CALC:REL:POW or CALC:REL:AUTO ONCE.
Page 322: Processing The Results Of Two Sensors
R&S NRP Annex: Remote Control - Commands Processing the results of two sensors The R&S NRP offers measurement commands for processing the results of two sensors. The calculated result can also be partly referenced to a stored reference value. The measurement commands are obtained by adding one of the following keywords: (difference) :DIFF :DIFF:REL (difference with reference value)
Page 323: Selecting A Measurement Mode
Annex: Remote Control - Commands R&S NRP Selecting a measurement mode Other MEAS commands are available for measurements to be performed in a mode other than the ContAv mode. The short form of these commands is obtained by adding a keyword for the measurement mode to keyword MEAS.
Page 324 R&S NRP Annex: Remote Control - Commands MEAS:ARRay? (1000) 1000 measured values are recorded in the ContAv mode. After termination of the last measurement, the results are stored in the output queue. There is no triggering as in the ContAv mode. The measurement result is a list of 1000 measured values separated by a comma.
Page 325: Selecting The Output Unit For Measured Values
Annex: Remote Control - Commands R&S NRP Selecting the output unit for measured values So far, no information has been given on the unit of the measured values. It is possible to modify the output unit of the measured values. A distinction is made as to whether the result represents a power or a power ratio.
Page 326: Division Of Meas
R&S NRP Annex: Remote Control - Commands Division of MEAS? MEAS? can be divided into other high-level measurement commands. ⇔ CONF [<parameters list>] MEAS? READ? [<parameters list>] The CONF command configures the measurement, whereas READ? starts the measurement, and calculates and provides the result. This division offers two advantages: 1.
Page 327 Annex: Remote Control - Commands R&S NRP Example: CONF TRIG:SOUR BUS INIT FETCh? ( Å -214, "Trigger deadlock", *TRG or GET is not possible if FETCh? is waiting). 1144.1400.12 Annex - I.8...
Page 328: Trigger State System
R&S NRP Annex: Remote Control - Commands Trigger state system The accuracy of a result largely depends on how accurately the sequence of a measurement can be determined. The R&S NRP manages a trigger state system to SCPI 1999.0 for each sensor to define the exact start and stop time of a measurement.

INITIATED IDLE *RST, PowerOn INIT:IMM INIT:CONT ON Fig. I-1: Overview of basic relationships in the trigger state system Fig. I-1: Overview of basic relationships in the trigger state system shows the basic structure of the trigger system.
Page 330: Logic Relationship Of Command Systems Sense, Calculate And Unit
R&S NRP Annex: Remote Control - Commands Logic relationship of command systems SENSe, CALCulate and UNIT The following section provides an overview of the measurement procedure of the R&S NRP. The commands are mentioned as examples. These commands are described in detail in chapter 6. To perform measurements with the R&S NRP, the user should have a good understanding of the trigger system and be familiar with the result processing.
Page 331: Measuring With Low-Level Commands
Annex: Remote Control - Commands R&S NRP Measuring with low-level commands Low-level commands allow the user to perform the most important modifications on the measurement configuration. In the present context, low-level commands are all commands that do not belong to high- level commands.
Page 332 R&S NRP Annex: Remote Control - Commands If triggering needs to occur in response to a rising signal edge, the trigger system has to be configured with TRIG:SOUR INT and TRIG:SLOP POS: *RST TRIG:SOUR INT (triggering in response to a signal edge) TRIG:SLOP POS (triggering in response to a rising signal edge) INIT FETCh?
Page 333 Annex: Remote Control - Commands R&S NRP Example: *RST TRIG:SOUR INT (starts measurement 50 µs after the trigger event) TRIG:DEL 50 us (starts next trigger event 800 µs after the trigger event at the earliest) TRIG:HOLD 800 us INIT FETCh? Another way to modify the trigger system timing is to set a holdoff time (TRIG:HOLD).
Page 334 R&S NRP Annex: Remote Control - Commands Level, hysteresis and dropout time With internal and external triggering (TRIG:SOUR INT | EXT), a trigger event is recognized when the level of a trigger signal exceeds a specific value. This value is the trigger level and can be set with TRIG:LEV.
Page 335: Configuration Of Sensor Settings
Annex: Remote Control - Commands R&S NRP Configuration of sensor settings The sensor settings are controlled by the SENSe command system. The sensors tell the basic unit which commands they understand and which parameters are allowed. As a result, the commands described below cannot be used for some sensors.
Page 336 R&S NRP Annex: Remote Control - Commands • Scope mode (SENS:FUNC "XTIM:POW"): This mode is used to determine a large number of measured values in succession. The number of required measured values is set with SENS:SWE:POI and the total measurement time with SENS:SWE:TIM. Note that each measurement must be triggered separately.
Page 337 Annex: Remote Control - Commands R&S NRP Automatic filter setting: SENS:AVER:COUN:AUTO:TYPE NSR | RES is used to select whether the noise component should remain below a specific threshold (NSR) or the measurement result should be stable specific accuracy (RES). avoid long measurement times,...
Page 338 R&S NRP Annex: Remote Control - Commands Measured-value corrections The R&S NRP offers different options for correcting measured values in the instrument. These options all require an existing knowledge of the test setup or the time structure of the signal. Offsets in the result can be corrected globally and depending on the frequency, and it is possible to consider the duty cycle of a signal and the influence of the complex reflection coefficient ( Γ...
Page 339: Configuration Of Calculate Blocks
Annex: Remote Control - Commands R&S NRP Reflection coefficient of the source (source gamma, Γ ): Reflections at the power source may • distort the result. If the reflection coefficient of the source is known, it can be specified for the measured-value correction via command path SENS:SGAM.
Page 340: Optimization Of Measurement Speed
R&S NRP Annex: Remote Control - Commands Optimization of measurement speed The duration of a message can be reduced by making the following setting: (deactivates screen content !!!) SYST:SPEed FAST The following settings also affect the measurement speed to a greater or lesser extent. Which of these settings are possible, however, depends on what is to be measured.
