Mfj 225 graphic antenna analyzer

The MFJ-225 has all the functions of a standard analyzer plus a series of new functions, such as Built-in LC display, 2 ports Vna and the USB port. The MFJ-225 does not require calibration (self-calibration)! Very easy to use. All the functions are described in the English manual supplied.  {

two antenna analyzers in one!  {
The MFJ-225 is a complete, self-sufficient analyzer, which is battery-powered and therefore the antenna can be installed directly. Connect the device to the PC and use the IG-Mini Vna Freeware to create a real 2 channel VNA and make an in-depth analysis of the data. It is also possible to print the graphic curves in addition to the numerical results.  {

See others!  {
thanks to the built-in, illuminated by 3 "graphic display, you will always have all the values ​​in sight. In addition to the presentation of discrete values, the SWR can also be reported in the graph as a curve. Other important values ​​displayed are impedance, V / R ratio, phase corner. Set center-freeze with a knob on the side of the MFJ-225 and read the curve in full screen mode on the display. {

frequency range 1.5-179.9 MHz
The MFJ-225 analyzer covers the entire frequency range from 1.5 MHz to 179.9 MHz continuously with the help of an integrated DDS-VFO system with 1 kHz resolution, so that all mechanical elements such as Switch or the controller are no longer necessary. The adjustment is carried out by an optical encoder.  {

Built-in signal generator!  {
The MFJ-225 uses a BUILT-IN CON-5DBM power generator Power to test different components such as mixer, amplifier, filter etc. the signal has a good suppression of the harmonic of-50dbc and provides excellent test results.  {

versatile feeding! 
For the functioning of the MFJ-225 it is possible to use 4 AAA batteries (rechargeable or alkaline). These are installed inside the device. With a 12V socket attacked on the side, one is also able to recharge the batteries. An LED light indicates the state of charge. A USB cable does not work also as a power supply for the MFJ-225 when connected to a PC.  {
