PDF User Manual for MFJ-224 (MFJ 224 MFJ224) :  

MFJ-224 (MFJ 224 MFJ224) technical specifications : 



The MFJ-224 is a revolutionary handheld 2 Meter FM Signal Analyzer™ that lets you:

* Measure signal strength with over 60 dB dynamic range.
* Check and set FM deviation of your packet and voice radios.
* Measure antenna gain, beam width, front-to-back ratio, side lobe suppression.
* Measure actual feed line loss in dB.

Plug in any scope and your MFJ FM SignalAnalyzer™ becomes a service monitor! It lets you visually analyze modulation, noise, and instantaneous-peak deviation. You can tune in any signal between 143.5 and 148.5 MHz. Its built in discriminator-meter function makes accurate tuning simple and easy. You can plug in headphones to help you tune in and identify signals with precision.

Here are some countless jobs your MFJ-224 FM SignalAnalyzer™ can perform...

* Evaluate Antenna Performance
Measure key yagi specifications such as gain over a dipole (dBd), beamwidth, front-to-back ratio and sidelobe suppression.
* Compare antennas to see which works best.
Check real-world performance of experimental antennas against computer predictions.
* Detect Feed line Faults
Document end to end cable loss in dB. See how much signal is actually lost between the antenna and the radio. Find out if kinks, corrosion and moisture have deteriorate performance - or if a new feed line meets factory specs.
* Plot Field Strength Patterns
Plot repeater or packet node field strength in dBm or microvolts throughout the coverage area. Find out where the signal is going - and where it isn't. Evaluate the impact of position changes with accuracy.
* Position Your Antennas
Take your MFJ-224 to the mountain, on the roof, or up your tower to position antennas for best possible performance - a few feet either way can make a big difference over difficult paths. Aim yagis with absolute pin-point accuracy.
* Measure Preamp Gain
Tune preamps for best gain and noise figure using your meter, a scope, and a weak signal source. Measures gain in dB.
* Nail Jammers Fast
Track down hidden transmitters - or nail jammers fast! High resolution 60 dB RSSI display is amateur radio's most accurate S-meter.
* Check and Set Deviation
Measure transmitter deviation anywhere in the band. Use the built-in meter display with a test-tone or plug into a scope for accurate instantaneous-peak readings on speech, packet, DTMF and CTCSS tones. Help your fellow HAMs - the MFJ-224 can measure the deviation of any signal you can hear!
* Analyze Audio Quality
Use the oscilloscope output to visually evaluate the quality of speech or tones by viewing the audio waveform. See if tones are clipped or distorted or if the speech limiter is working improperly. Solve FM audio problems fast!
* Scan the Band
Tune in and identify signals using monaural or stereo headphones. Check speech quality of your radios or use as a second receiver to monitor activity.
* Tune Transmitters and Filters
Use with RF-sniffer probe to tune low-power transmitter stages. Tune high-Q filters and networks for best response, lowest loss.

The revolutionary MFJ-224 2 Meter FM SignalAnalyzer™ may be the most useful 2 Meter handheld test instrument you may ever own. There's also a battery check function. Requires a 9 volt battery (not supplied). Measures 4 x 2˝ x 6ľ inches (92x190x45 mm).
