METROPWR FX771, is a modern VECTOR POWER/SWR METER completely digital. It’s composed of a wattmeter and a power coupler for measurements up to 3/5kW. It has a very modern and slim design, and very high performance. It has inside a fast 32bit processor plus a coprocessor to handle all the measurements in real time, and measure Power (AVG, PeP, dBm) , SWR, R, Z, X, %Mod and more. It has a fast external bus with which you can connect many accessories in series:
- Antenna switch 1X4 positions
- Radio switch 1X4 positions
- Directional coupler FX3 3kW
- Directional coupler FX5 5kW
- Power switches FX7
In the photo some examples of connecting some accessories. Metropwr Fx771 can handle 4 antennas and 4 radio simultaneously. Through a menu it is possible to cross each radio with each antenna.
To understand the potentialities of the METROPWR FX771 Wattmeter, I attach some link diagrams. The potentialities are enormous thanks to the scalability and expandability of the instrument. Perhaps calling it a wattmeter is somewhat diminutive as in the Metrovna I thought in great designing a tool that can measure almost any power at almost any frequency as well as handle all antennas and radios at the same time. In short, a UNIQUE tool in its genre and perhaps never seen to this day. As for the Metrovna, I wanted to integrate all the features of the trade tools and integrate them into a highly high tech wattmeter. Starting with the unique design of the SMART functions, in addition to the common tools seen in the last decades. Calling on the chats in photos under some link diagram:
– Easy for HF / 50MHz 3 / 5kWatt
It has a large Lcd touch screen display very fast and responsive, 10 front leds with which you can monitor:
- Measurement errors
- High SWR alarm
- RX/TX/Standbye
- Monitoring ADC/ACT
- USB PC RX/TX
- Check Bus I2C
