    1.8.2 Startup ► Press the ON/STANDBY key to switch to ready state. The R&S NRP2 initiates its startup procedure, i.e. it boots the operating system, automatically performs a selftest and starts the instrument firmware. If the previous session was terminated regularly, the instrument uses the last setup with the rele- vant instrument settings.
  • Page 23 Fig. 1-8: Start screen with access to Firmware Update and Bootmenu 1.8.2.2 Function check After switch-on, the R&S NRP2 performs a function test. The contents of all non-vola- tile memories, the RAM and the addressability of the interfaces are checked. Mes- sages indicate the options the instrument is equipped with.
  • Page 24 . When finished, the instrument displays the result under the network icon, i.e. "OK" indicates that the interface can be addressed. If the R&S NRP2 is not connected to a network hub or if a connection cannot be established during booting, the message (Not Connected) is displayed instead of "OK".
  • Page 25 If an error is detected when the non-volatile memory containing instrument settings is checked, an error message is displayed when booting is completed. The non-volatile memory is then re-initialized completely and the R&S NRP2 goes into the preset state. All instrument settings that have been saved are lost as a result of this procedure.

Timeslot mode: SENS:FUNC "POW:TSL:AVG" After the trigger event, the power is measured in timeslots, the number of which is defined with SENS:TSL:COUN. The length of the timeslots is set with SENS:TSL:WIDT.
  • Page 395 Annex NRP2 Programming Measurements Averaging/filters The power values to be measured are sampled by the sensors. The sampling values then undergo two-stage filtering before they are made available as measured values. The first filter stage is a time integration. The integration time is either set explicitly (ContAv mode: SENS:APER, Timeslot mode: SENS:TSL:WIDT and Trace mode: SENS:SWE:POIN and -:TIME) or determined automatically ("BurstAv mode").
  • Page 396 Measured-value corrections The R&S NRP2 offers different options for correcting measured values in the instru- ment. 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) of the power source.
  • Page 397 FETCh? This example assumes that a table called "Table 1" is available. Duty cycle If the duty cycle of a pulsed signal (SENS:DCYC) is reported to the R&S NRP2, the R&S NRP2 delivers the average power in the pulse. Example...

  • Page 401 Annex NRP2 Programming Measurements In the following example, sensor B is configured for a trace measurement as trigger master. Sensor A acts as trigger slave and performs a ContAv measurement. Sensor A will be started first and immediately enter WAIT_FOR_TRIGGER state. It will remain in this state, until an external trigger occurs.

  • Page 402: Compatibility Information

    CALC8:MATH "(SENS2)" A.5 Compatibility Information This section contains information regarding the compatibility of the R&S NRP2 remote control commands with those of the "E4418B" and "E4419B" power meters from Agi- lent. The R&S NRP2 is largely downward-compatible to the above-mentioned instru- ments but offers additional capabilities.
  • Page 403 :RWLock TRACe:STATe Is not implemented in the R&S NRP2. TRACe:DATA? Is not implemented in the R&S NRP2 in this form. Data of the trace mode can only be queried via the high-level commands (FETCh?, READ?, MEAS?) and CALC:DATA?. TRACe:UNIT? The UNIT node is only globally available in the R&S NRP2 and...
  • Page 404 E4418B/E4419B command Compatibility information TRIGger[:SEQUence[1]|2] The R&S NRP2 does not recognize the :SEQUence header and uses no TRIGger command globally but only on a sensor-by-sensor basis. If TRIGger or SENSe commands are to have a global effect, the :ALL header must be used instead of the numeric suffix.
