METROPWR FX773 5″+ Coupler FX3
The FX-77x is a measuring system for HF signals whose remote sensors are looped directly into the antenna cable. A large display (touchscreen) shows the measured values, with an optional switch several antennas and radios can be combined.
The measurement technology for HF signals is becoming more and more perfect in order to be able to cope with demanding tasks. The FX-771/3/5 is the heart of the ‘Metropwr’ measuring system, which is suitable for many tasks in the shack with external sensors and switches. This control and display unit is equipped with a powerful microprocessor and is operated via a colored LC touch display.
The integration into the station takes place via a USB 2.0 interface to the PC. Appealing operating software is available for the Windows PC, with which the measurement data can also be displayed there.The external Metropwr sensors can be installed up to 5m away from the control panel. Sensors for shortwave up to 3 or 5 kW are available. The sensors are intended for indoor use (not weatherproof) and contain a directional coupler, via which the measurement data is signaled to the main device. The FX-771/773/775 comes with a short wave sensor FX-3.The displayed data includes everything you need for the analysis of the HF signal and the antenna system. The power can be measured in real time, with functions such as average, peak power and display in watts or dBm. In addition to the VSWR, various measured values such as R, Z and |X| be determined, the transmission signal can be examined for the degree of modulation.
This makes it easy to check that the transmission signal is “clean”.A remote-controlled 4 to 1 switch for shortwave is available as an option. In this way, complex systems with several antennas and radio devices can be set up. In combination with a Metropwr sensor, complete antenna controls can be implemented. The changeover switch does not require its own power supply and can be set up up to 5m away from the operator panel.
For particularly precise measurements, or measurements in other frequency ranges, there is the option of addressing a ‘Bird 43’ wattmeter via the MetroPWR’s expansion bus and integrating it into the overall system. See article FX-43 Interface for Bird-43. A maximum of two FX-7 switches can be connected to the FX-771/3/5.
