METROPWR FX773, 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 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, and more. It has a fast external bus with which you can connect many accessories in series:
- Antenna switch 1X4 positions FX7
- Radio switch 1X4 positions FX7
- Directional coupler 3/5kW FX3/FX5
In the photo some examples of connecting some accessories. Metropwr Fx773/FX775 can handle 4 antennas and 4 radio simultaneously. Through a menu it is possible to cross each radio with each antenna.
In the picture the block diagram of the FX773 / FX775. The heart is a powerful 32bit uP with a second uP used to manage all measurements in real time.
To understand the potentialities of the METROPWR FX773/FX775 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.
It has a large Lcd touch screen display very fast and responsive, with which you can monitor:
- Measurement errors
- High SWR alarm
- RX/TX/Standbye
- Monitoring ADC/ACT
- USB PC RX/TX
- Check Bus I2C
