Page 119 ® Remote control commands R&S NRPM Controlling the measurement The following chapter introduces in general the principle of triggering and the con- trolling mechanisms for the output of the measurement results. 10.5.1 Triggering In a basic continuous measurement, the measurement is started immediately after the initiate command.
Page 120 ® Remote control commands R&S NRPM Controlling the measurement Measurement start Depending on whether you want to measure continuously or want to execute one dedicated measurement, select the corresponding command: ● on page 151 INITiate:CONTinuous Starts a new measurement cycle automatically after the previous one has been completed.
Page 121 ® Remote control commands R&S NRPM Controlling the measurement 10.5.2 Controlling the measurement results The R&S NRPM3(N) sensor module can cope with the wide range of measure- ment scenarios with the help of the so-called "termination control". Depending on how fast your measurement results change, you can define, how to retrieve the measurement results.

Page 138 To describe the format of the command response, it is important to know some additional information. Besides the average power, the R&S NRPM sensor module can measure addi- tional measurands like "Minimum", "Maximum" or "Random". These additional measurands are denoted as auxiliary measurands and can be selected with the on page 131 command.
Page 139 R&S NRPM Configuring the measurement modes A trace measurement with the R&S NRPM can therefore be configured to return up to three measurands on each channel/antenna module. As a consequence, the resulting data which is provided by a [SENSe<Sensor>:]TRACe:DATA query can contain between 1 and 9 blocks of measurement data. For example, 1 resulting measurement data block if only one antenna module is used and only average power is to be measured on that channel.

Page 142 ® Remote control commands R&S NRPM Configuring the measurement modes Usage: Query only [SENSe<Sensor>:]TRACe:MPWidth? Queries the attainable time resolution of the trace mode. The result is the small- est possible distance between two pixels, i.e. it is the smallest time interval that can be assigned to a pixel.
Page 143 ® Remote control commands R&S NRPM Configuring the measurement modes If disabled, each measurement from the sensor module is averaged. If enabled, only one sampling sequence per measurement is recorded, thus increasing the measurement speed. With a higher measurement speed, the measured values of an individual measurement are immediately delivered.
Page 144 ® Remote control commands R&S NRPM Configuring basic measurement parameters SINC Returns the trace data as the result of a SINC interpolation of the acquired samples. This setting is only reasonable if the selected number of trace points is higher than the num- ber of samples which results from the internal sample rate in the selected trace time.

Page 146 ® Remote control commands R&S NRPM Configuring basic measurement parameters In this case, previous measurement results still contained in the averaging filter strongly affect the settling of the display. As a result, the advantage of detecting trends in the measurement result while the measurement is still in progress, is lost.

For achieving better accuracy, the carrier frequency of the applied signal must be set.
Page 148 Sets the duty cycle for measuring pulse-modulated signals. The duty cycle defines the percentage of one period when the signal is active. If the duty cycle is enabled, the R&S NRPM calculates the signal pulse power from the average power considering the duty cycle in percent.
Page 149 ® Remote control commands R&S NRPM Starting and ending a measurement The attenuation of an attenuator located ahead of the sensor module (or the cou- pling attenuation of a directional coupler) is considered with a positive offset, i.e. the sensor module calculates the power at the input of the attenuator or the direc- tional coupler.

It is however advisable to check the nominal data from time to time. 13.1 Cleaning Do not use any liquids for cleaning. Cleaning agents, solvents (thinners, acetone), acids and bases can damage the labeling, plastic parts and display.

As a manufacturer, Rohde & Schwarz completely fulfills its obligation to take back and dispose of electrical and electronic waste.
Page 195 ® Remote control basics R&S NRPM SCPI command structure Annex Remote control basics ● SCPI command structure................195 ● Status reporting system................202 SCPI command structure SCPI commands - messages - are used for remote control. Commands that are not taken from the SCPI standard follow the SCPI syntax rules. The R&S NRPM3(N) sensor modules support the SCPI version 1999.
Page 196 ® Remote control basics R&S NRPM SCPI command structure *ESR? EVENT STATUS QUERY Queries the contents of the event status register. *IDN? IDENTIFICATION QUERY Queries the instrument identification string. A.1.2 Syntax for device-specific commands Long and short form The mnemonics feature a long form and a short form. The short form is marked by upper case letters here, to distinguish it from the long form, which constitutes the complete word.
Page 197 ® Remote control basics R&S NRPM SCPI command structure Optional mnemonics Some command systems permit certain mnemonics to be inserted into the header or omitted. These mnemonics are marked by square brackets in the description. The instrument must recognize the long command to comply with the SCPI standard.
Page 198 ® Remote control basics R&S NRPM SCPI command structure ● Text ● Character strings ● Block data The parameters required for each command and the allowed range of values are specified in the command description. Numeric values Numeric values can be entered in any form, i.e. with sign, decimal point and exponent.
Page 199 ® Remote control basics R&S NRPM SCPI command structure ● NAN Not A Number (NAN) represents the value 9.91E37. NAN is only sent as a instrument response. This value is not defined. Possible causes are the divi- sion by zero, the subtraction of infinite from infinite and the representation of missing values.
Page 200 ® Remote control basics R&S NRPM SCPI command structure Block data Block data is a format which is suitable for the transmission of large amounts of data. A command using a block data parameter has the following structure: Example: SYSTem:HELP:SYNTax:ALL? Response: #45168xxxxxxxx The ASCII character # introduces the data block.
Page 201 ® Remote control basics R&S NRPM SCPI command structure The hash symbol introduces binary, octal, hexadecimal and block data. ● Binary: #B10110 ● Octal: #O7612 ● Hexa: #HF3A7 ● Block: #21312 A "white space" (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the parameters.
Page 202 ® Remote control basics R&S NRPM Status reporting system Example: TRIG:LEV 0.1E-3 TRIG:DEL 3E-3 A.1.6 Responses to queries A query is defined for each setting command unless explicitly specified otherwise. It is formed by adding a question mark to the associated setting command.

Page 206 ® Remote control basics R&S NRPM Status reporting system part can only be read, but not written into or cleared. Its contents are not affected by reading. PTRansition / NTRansition status register part The two transition register parts define which state transition of the CONDition part (none, 0 to 1, 1 to 0 or both) is stored in the EVENt part.
Page 207 ® Remote control basics R&S NRPM Status reporting system ENABle bit = 1: if the associated EVENt bit is "1", the sum bit is set to "1" as well. This part can be written into and read by the user as required. Its contents are not affected by reading.
Page 208 ® Remote control basics R&S NRPM Status reporting system Bit No. Meaning Error queue not empty The bit is set if the error queue has an entry. If this bit is enabled by the SRE, each entry of the error queue generates a service request. An error can thus be recognized and specified in detail by querying the error queue.

Page 216 ® Remote control basics R&S NRPM Status reporting system A.2.8.1 Operation calibrating status register The CONDition register contains information about whether a sensor module is currently being calibrated and, depending on the configuration of the transition register. The EVENt register indicates whether a calibration was started or com- pleted since the last readout of this register.
Page 217 ® Remote control basics R&S NRPM Status reporting system A.2.8.3 Operation trigger status register The CONDition register contains information about whether a sensor module is currently in the waiting for trigger state, i.e. expecting a trigger event and, depending on the configuration of the transition register. The EVENt register indi- cates whether the waiting for trigger state was entered or quit by a sensor module since the last readout of the register.
