2.2.2 Test Procedure
1) Set up the source antenna with RWC1020A inside the RWC7100A to be located in the center.
2) Connect the spectrum analyzer and reference antenna with RF cable. (If necessary, use an adequate RF amplifier
together.)
3) Set up the spectrum analyzer as follows:
- Center Frequency: 400.1MHz (Change to 900.1MHz, 2400.1MHz, 5800.1MHz, respectively)
- Span: 500Hz
- Resolution BW: 4.7Hz (or Auto)
- Reference Level: 0dBm
- Scale 20 dB/div
4) Set up the signal generator or RWC1020A as follows:
- Frequency : 400.1MHz
- Power : +10dBm
5) Open the RWC7100A door and measure the power (Pref) moving the reference antenna to several points as
shown in Figure 2-3.
[Figure 2-3] Check the reference power level (Door Opened)
6) Close the RWC7100A door and measure the output power(Pmes) moving the reference antenna at the same
positions in step 5)
[Figure 2-4] Check the measure power level (Door Closed)
7) Calculate the Shielding Effectiveness Pse[dB] = Pmes[dBm] - Pref[dBm].
8) Change the signal generator to the next frequency and repeat the measurement process, step 3) to 7)
