Main features:

  • Operating frequency from 1.8 – 500MHz.

  • Signed phase metering up to 500MHz.

  • Two points of measurement, at the sensor point and at the antenna point. 

  • Phase measurement between sensors.*

  • Real time temperature compensation in the meter and the sensor.

  • Every meter and every sensor individually calibrated for the best accuracy. Temperature controlled, computer automatized calibration setup makes over 10,000 calibration points in each meter and over 100 points in each sensor. Calibrated per port for level, frequency, phase, and temperature.

  • Dual, high speed, three color, user adjustable auto-ranging LED bar graphs with configurable peak hold.

  • Very wide viewing angle, sunlight readable, high contrast graphics OLED display.

  • Multiple, user configurable display screens for powers, impedances, waveform, spectrum, IMD ... 

  • Single and Dual channel modes, auto mode for SO2R, special 4IN direct input mode.

  • User configurable alarms (SWR, High Power, Low Power, PSK IMD, Arcing) in three stages (Warning, Alarm, Fault) for two power levels on per sensor, per band basis.


  • Internet enabled, native IEEE 802.3 Ethernet port for remote connectivity, no computer required.

  • Internal HTTP server for seamless access from the computer browser for status checking, maintenance and firmware updates. No drivers, no specialized software installation.

  • Internal VNC server for remote access to complete setup.

  • Dedicated TCP port for high speed remote control applications, open protocol.

  • Free Remote Control application provided for Windows and OS-X.

  • Legacy RS232 port.

  • High purity, DDS based test signal generator (single/dual tone, noise) for linearity and bandwidth tests.

  • Two keying, configurable ports (2x IN, 2x OUT) for protections.

  • iLINK port for simplified connectivity to our interfaces.

  • Auxiliary port for future expansions (wall mount 7 segment LED displays, analog meter).


Other features:

  • Internal speaker for audible warnings.

  • Internet synchronized real time clock.

  • Ambient light sensor for led bars and display brightness control.

  • Fully EMI shielded, aluminum die cast enclosure.

Internal processing highlights:

  • 210 MIPS, 32bit floating point Cortex M4 DSP processor for extremely fast updates and accurate calculation of complex functions.

  • Hi-grade, parallel 16bit ADC, sampled at 125ksps.

  • 24bit DAC at 160ksps for signal generator.

* Both sensors are of the same type (U/I or FWD/REF), connected by the same length leads and operating at the same frequency.
