Supply Scope

  • MFJ-225 Antenna Analyzer
  • Operating instructions (EN)
The MFJ-225 has got all functions of a standard analyser plus a variety of new functions, such as built-in LC display, 2 port VNA and USB port. The MFJ-225 does not require calibration (self-calibrating)! Very easy to use. All functions are described in the included English manual.

Two antenna analysers in one!

The MFJ-225 is a complete, self-contained analyser that is battery-powered and thus can be installed directly at the antenna. Connect the device to a PC and use the IG-mini VNA freeware to create a fully-fledged 2-channel VNA and do extensive data analysis. You can also print graphical curves in addition to your numerical results.

View more!

Thanks to the built-in, illuminated 3″ graphic display, you will always have all the values in view. In addition to the presentation of discrete values, the SWR can also be plotted graphically as a curve. Other important displayed values are Impedance, V/R ratio, phase angle. Set center-frequencies with a knob on the side of the MFJ-225 and read the curve in full screen mode on the display.

Frequency range from 1.5 to 179.9 Mhz

The MFJ-225 analyser covers the entire frequency range from 1.5MHz to 179.9 MHz continuously with the help of an integrated DDS-VFO with 1 khz resolution, so all mechanical elements like switches or controller are no longer necessary. The adjustment is done by an optical encoder.

Built-in signal generator!

The MFJ-225 uses a built-in signal generator with -5dBm power output to test several components such as mixer, amplifier, filter etc. The signal has a good suppression of harmonics of -50dBc and provides for excellent test results.

Versatile power supply!

For operation of the MFJ-225 you can use 4 AAA (rechargeable or Alkaline) batteries. These are installed inside the device. With a 12V socket attached on the side, you are even able to recharge the batteries. A LED light shows the charging status. A USB cable does also function as a power supply for the MFJ-225 when connected to a PC.
