Magnetic radiation tester signal source of the basic parameters in general?

The signal source of the magnetic radiation tester used to test the electromagnetic shielding performance of the standard group/body testing textiles, plastic fabrics, non-conductive materials surface coating/plating, metal sheet, metal mesh, conductive film, conductive glass, conductive dielectric panels, etc. The signal source of the magnetic radiation tester will have the following basic parameters:

1.test frequency range: 300 KHz-3000MHz;

2. frequency Stability: ≤±5×10-6;

3. Frequency resolution: 1 Hz;

4. Signal purity: ≤-65dBc/Hz (off 10KHz);

5. Output level: -45dBm-+10 dBm;

6. Level accuracy: ≤±1.5dB (25°C±5°C, -45dBm-+5dBm). +5 dBm);

7. Harmonic rejection ratio: ≥30dB(1MHz-3000MHz), ≥25dB(300KHz-1MHz);

8. Directionality: ≥50dB(after vector calibration);

9. Power Sweep: -8dBm-+5dBm;

10. System Impedance: 50 Ohm.
