DESCRIPTION :
MZM-3004 has been designed from a Stereo Radio Tuner equipped with the most advanced reception circuits. Each one of the functional sections has several test points which permit the analysis and monitoring of the main electrical signals of the turner. All the test points are protected against accidental shorting.
FEATURES :
- Alternative frequency (AF)
- Digital Tuning
- Digital Signal Level Display
- Frequency range (FM, MW, LW)
- AM : 531-1,602 KHz, 153-279 KHz
- Direct through frequency introduction
- Automatic Broadcast Station search
- Menu Selection Display
- Preset FM and AM sections
FAULT SIMULATOR :
The fault simulator manipulates electric points of the tuner, to simulate real faults.
GENERAL SPECIFICATION :
- DC Output: 3.3V, 5V,8V 0.2A
- Operating temperature: 0 to 45C, 85% OR Less(R.H)
- Input Power:AC 240V, 50Hz 1-Phase
