R&S®NRT

Power Reflection

Meter Family

At a glance

The R&S®NRT-Zxx directional power sensors are self-contained

measuring instruments. They can be connected directly

to the R&S®NRT2 or, via the R&S®NRT-Z5 USB interface

adapter, to the PC (communications via USB).

The compact R&S®NRT2 power reflection meter supports

all the measurement functions of the R&S®NRT-Zxx directional

power sensors. The large, user-friendly touchscreen

simultaneously displays the forward and reverse power.

The base unit is exceptionally easy and intuitive to use and

can be remotely controlled via LAN, GPIB (R&S®NRT2-B8

option) or USB.

Key facts

??Simultaneous display of forward and reverse power

??Measurement of average power, average burst power,

peak power, crest factor, CCDF and mismatch

??5" color touchscreen

??Direct operation of the R&S®NRT-Zxx directional power

sensors from a PC

??Frequency range from 25 MHz to 4 GHz

(sensor-dependent)

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-Zxx directional power sensors 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

calculated 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 reflection

ratio in %.

Analog bargraph and autoscale

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 outside

the defined limits are highlighted in red. The analog

bargraph additionally graphically displays the defined limits

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 programming

required). The R&S®NRT2 power reflection meter can

be remote controlled via USB or LAN. The R&S®NRT2-B8

option adds remote control via GPIB (IEEE 488).
