Directional power sensors measure forward and reverse power under operating conditions. These measurements are required when installing, servicing and monitoring transmitters, antennas and RF generators. The NRT family consists of the NRT2 power reflection meter and various NRT-Zxx directional power sensors. Thanks to their wide range of measurement functions and high accuracy, they can be used in research, development and production.
The NRT-Zxx directional power sensors are self-contained measuring instruments. They can be connected directly to the NRT2 or, via the NRT-Z5 USB interface adapter, to the PC (communications via USB).
The compact NRT2 power reflection meter supports all the measurement functions of the 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 (NRT2-B8 option) or USB.

| Benefits |
|
| Simple Touchscreen Operation | Thanks to intelligent menus, the compact 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 sub-menus.
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 NRT-Zxx directional power sensors simultaneously measure forward and reverse power and calculate additional parameters such as load matching.
The 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 NRT2 are 100% code compatible with the command set of the previous NRT model.
This simplifies device replacement and integration into existing systems (no additional programming required).
The NRT2 power reflection meter can be remote controlled via USB or LAN.
The NRT2-B8 option adds remote control via GPIB (IEEE 488).
