R&S®NRT2 POWER REFLECTION METER Simple touchscreen operation Thanks to intelligent menus, the compact R&S®NRT2 base unit with a state-of-the-art 5" touchscreen is extremely easy to operate. On the top menu level, users can switch between the most important measurements. Additional parameters can be set in clearly structured submenus. Important functions such as setting frequencies, zeroing and creating screenshots can be accessed at the push of a button. Simultaneous display of forward and reverse power The R&S®NRT-Z14 and R&S®NRT-Z44 directional power sen- Analog bar graph with configurable limits sors simultaneously measure forward and reverse power and calculate additional parameters such as load matching. The R&S®NRT2 power reflection meter then displays one forward and one reverse parameter at the same time. The forward measurement function shows the average power, average burst power, peak envelope power (PEP) and the peak-to-average power ratio (crest factor). The cal- culated absorption average power (forward minus reverse), absorption burst power, absorption PEP and amplitude distribution (CCDF) for modulated signals can also be displayed. The reflection measurement function displays the average power, return loss, SWR, reflection coefficient and reflec- tion ratio in %. Analog bargraph and autoscale Forward measurement function Measurements can be shown as numeric values or in an analog bargraph. To define the analog measuring range, the user starts the autoscale function by simply pressing a button. The scale of the analog bargraph is optimally adjusted to the measured signal. Visual limit monitoring Each measurement can be visually monitored. Values out- side the defined limits are highlighted in red. The analog bargraph additionally graphically displays the defined lim- its in red. 100 % code compatibility with predecessor model The remote commands of the R&S®NRT2 are 100 % code compatible with the command set of the previous R&S®NRT model. This simplifies device replacement and integration into existing systems (no additional program- ming required). The R&S®NRT2 power reflection meter can be remote controlled via USB or LAN. The R&S®NRT2-B8 Reflection measurement function option adds remote control via GPIB (IEEE 488). 4

Direct power monitoring on a PC The R&S®NRT-Zxx directional power sensors are fully cali- brated, independent measuring instruments that can also be used without the base unit. The R&S®NRT-Z5 USB inter- face adapter enables direct connection to a laptop/PC. The R&S®NRT-Z14 and R&S®NRT-Z44 power sensors make high-precision power and reflection measurements extremely cost-effective. Direct monitoring on a PC is very useful in applications where data needs to be collected (e.g. in development labs and for maintenance of base sta- tions) as well as for purely remote controlled applications such as power monitoring in transmitter stations and EMC test systems. The R&S®Virtual-NRT Windows user interface (provided as a free download) allows users to define mea- surement functions and also display and store individual results and series of measurements. 6

VERSATILE APPLICATIONS Continuous monitoring of transmitter systems Power measurements with digital modulation Many applications need continuous monitoring of power Conventional directional power meters only measure RF and reflection, e.g. to enable fast reaction times when and microwave signals that have an unmodulated enve- an antenna is damaged. This requires a highly accu- lope. The R&S®NRT-Z14 and R&S®NRT-Z44 directional rate measuring instrument that does not influence the power sensors have been designed to also meet the SWR and attenuation of the antenna feeder and does not requirements of digitally modulated signals. The key fac- generate any interfering signals. The R&S®NRT-Z14 and tor is their ability to correctly measure the average power R&S®NRT-Z44 directional power sensors feature good (RMS value) of a signal irrespective of its envelope. The matching, low insertion loss and excellent intermodula- sensors behave like a thermal power meter and offer the tion characteristics. When a multicarrier signal is applied, best accuracy and measurement range (35 dB to 40 dB). the sum power is displayed – a feature rarely found in con- ventional directional power sensors. Since data is digitally For TDMA systems, the average burst power function transferred, the length of the connecting cable is not criti- makes it possible to measure transmitter power in an cal and the R&S®NRT-Z14 and R&S®NRT-Z44 directional active timeslot. If several timeslots are active (e.g. base power sensors can be installed where they measure most stations), the average power function can determine the accurately – at the antenna feed point. average power over all timeslots. The peak envelope power function can measure overshoots at the beginning of a timeslot or peak values caused by modulation down to a minimum duration of 200 ns (R&S®NRT-Z44) or 1.5 µs (R&S®NRT-Z14). When measuring CDMA signals with the ¸NRT-Z44 directional power sensors, both the peak envelope power function and the average power function can be used. The peak envelope power function measures the short- time peak values that are approx. 10 dB above the average value. This provides information about the overdrive capa- bility of the transmitter output stage. The peak envelope power can be displayed as an absolute value in W or dBm or as a relative value in dB referenced to the average value (crest factor).

1) Depends on measurement function and direction. 2) Ratio of measured forward and reverse power in dB with perfectly matched load. 3) Specifications apply to measurement of forward power. 4) Values in [ ]: 2 ▷ 1 forward direction (if different from 1 ▷ 2 forward direction). 5) Power measurement below the specified limits is possible at the expense of increased influence of zero offset. 6) Measurement of average power up to the CW limits is possible at the expense of increased measurement errors. 7) Increased uncertainty with a coverage factor of k = 2. For normal distribution, this coverage factor has a coverage probability of 95 %. 8) With matched load (SWR max. 1.2) under consideration of the carrier frequency which must be input for an accuracy of 1 %; measurement results referenced to the load end of the sensor, averaging filter set to automatic mode (high resolution). The influence of the carrier harmonics can be ignored provided they are below −30 dBc up to 5 GHz. With an SWR of more than 1.2 on the load end, the influence of directivity on the measured forward power is to be considered. The associated increased uncer- tainty with a coverage factor of k = 2 is equal to 6 % of rdg (0.25 dB) × the load reflection coefficient. Example: a mismatched load with 3.0 SWR yields a 0.5 reflection coefficient, producing an additional uncertainty of 3 % of rdg (0.13 dB). The overall measurement uncertainty will be increased to 4.4 % of rdg (0.19 dB). 9) With matched load (SWR max. 1.2) under consideration of the carrier frequency which must be input for an accuracy of 1 %; measurement results referenced to the load end of the sensor, averaging filter set to automatic mode (high resolution). The influence of harmonics of the carrier can be neglected provided they are below −30 dBc up to 4 GHz, −35 dBc from 4 GHz to 10 GHz and −60 dBc above 10 GHz. With an SWR of more than 1.2 on the load end, the influence of directivity on measured for- ward power is to be considered. The associated increased uncertainty with a coverage factor of k = 2 equals 6 % of rdg (0.25 dB) × load reflection coefficient for carrier frequencies up to 3 GHz and 10 % of rdg (0.4 dB) × load reflection coefficient from 3 GHz to 4 GHz. Example: a mismatched load with 3.0 SWR yields a 0.5 reflection coefficient leading to an additional uncertainty of 3 % of rdg (0.13 dB) in the frequency range up to 3 GHz. Overall measurement uncertainty will be increased to 4.4 % of rdg (0.19 dB). 10) After zero adjustment. 11) In the temperature range from +18 °C to +28 °C; relative to a CW signal. The error depends on the modulation parameters for each case, e.g. the modulation frequency with AM and the individual sensor characteristics. The specified tolerances refer to 1 ▷ 2 forward direction and a power of 120 W (R&S®NRT-Z44). With burst signals, the specified errors refer to an average burst power of 120 W (R&S®NRT-Z14/-Z44). Since errors due to modulation are proportional to power, they become smaller the lower the power: a WCDMA signal with an average power of 30 W, for example, will only cause a very small error of about ±0.5 % of the R&S®NRT-Z44 sensor with modulation correction switched on. 12) With modulation correction switched on. 13) With modulation correction switched on (same as WCDMA); chip rate set to 3.6864 Mchip/s. 14) Signal similar to test model 1 with 64 channels for downlink with 3.84 Mchip/s in line with 3GPP standard 3G TS 25.141 V3.1.0 (2000-03); modulation correction switched on, chip rate set according to test signal. 15) Statistically distributed with a mean value of 0 %/K, the stated temperature coefficients correspond to approximately two standard deviations. Temperature coefficients must be considered for calculation of measurement uncertainty below +18 °C and above +28 °C. Example: at +5 °C and 1 GHz, a temperature drift of (18 − 5) × 0.25 % = 3.25 % of rdg (0.14 dB) for average power measurement can be expected relative to +18 °C. Combined with the measurement uncertainty of 3.2 % from +18 °C to +28 °C, the overall uncertainty will be 4.6 % of rdg (0.19 dB). 16) Typical values; measured with R&S®NRT-Z5, average time of 100 measurements. Measurement results settled with power-dependent (automatic) averaging. Each mea- surement time is defined as the time from the input of the trigger command up to the termination of the return string (baud rate 38.4 kbit/s). All measurement results consist of two measured values: one for the forward power measurement function and one for the selected reflection parameter (SWR, return loss, reflection coefficient or reflected power). 17) After zero adjustment, unmodulated burst signal with rectangular envelope. The burst power must be at least 4 W for the R&S®NRT-Z14 and the R&S®NRT-Z44. For the R&S®NRT-Z44, the burst width must be > 2 ms {4 kHz}, > 40 µs {200 kHz} and > 5 µs {”FULL”}. For the R&S®NRT-Z14, the burst width must be > 2 ms {4 kHz}, > 40 µs {200 kHz} and > 10 µs {”FULL”}. Since the measurement uncertainty is inversely proportional to the burst width and the power, it may be smaller or higher for other waveforms. 18) In the temperature range from +18 °C to +28 °C; video bandwidth “FULL“, PEP defined as power with a CCDF value < 10–6. 19) Setting must be initiated with a “rev:pow“ command in addition to the setting command for the forward measurement function via the remote interface of the sensor. Since the sensor measures average reverse power with this setting (a parameter normally not of interest in combination with any function other than average power measurement), the setting is denoted as “PEP measurement only“ or “CCDF measurement only“. 20) After zero adjustment, unmodulated burst signal with rectangular envelope, threshold value set to half the burst power. The burst power must be at least 4 W for the R&S®NRT-Z44. For the R&S®NRT-Z44, the repetition rate must be < 50/s {4 kHz}, < 2500/s {200 kHz}, and < 20000/s {”FULL”}. For the R&S®NRT-Z14, the repetition rate must be < 50/s {4 kHz}, < 2500/s {200 kHz} and < 10000/s {”FULL”}. Since the measurement uncertainty is proportional to the repetition rate and inversely proportional to the power, it may be smaller or higher for other waveforms. For spread spectrum signals such as cdmaOne, CDMA2000®(3x), WCDMA, DAB and DVB-T, the mea- surement uncertainty is optimally described by an uncertainty for the threshold setting. This uncertainty is taken into account in addition to the specified value. With modulation correction switched on, this additional uncertainty is approx. 5 % of the power value in W for the aforementioned standards. 21) Using double-shielded twisted pair cable with a characteristic impedance of 100 Ω and a cross section of ≥ 0.22 mm2 (24 AWG) for the data lines is recommended to achieve the advertised performance and electromagnetic immunity. Minimizing voltage drop can require a larger cross section of e.g. 0.5 mm2 (20 AWG) for the power supply lines.
