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).
