2.2. Performance Test

This product is a precision RF Shielding Enclosure manufactured to be robust. Please refer to the test procedure for

shielding effectiveness below to ensure optimal performance at all times. This product may need calibration

depending on the number of uses and period of use. Please refer to the Maintenance section for more details.

This product may require maintenance depending on the number of the lid’s opening and closing and the period of

use. Please refer to the maintenance section for more details.

2.2.1 How to Set up the Equipment Required for RF Shielding Effectiveness Test

The following devices are required to check the shielding effectiveness.

- Signal generator : capable of generating 400M-6400MHz tone signal

- Signal generator side antenna : omni-directional one

- Signal power meter : A spectrum analyzer or equivalent device that can measure the tone power of a signal source

- Signal receiving side antenna(Reference) : A broadband antenna with high gain characteristics that can receive even

weak signals well

- RF signal amplifier : capable of sufficiently amplifying weak RF signals, if necessary

When measuring the shielding effectiveness of RWC7100A, it is recommended to install a signal generator with a

built-in battery inside RWC7100A, and perform the measurement outside of RWC7100A. If a signal is generated from

the outside and input through a cable, it is not guaranteed that the test results would be accurate.

Refer to Figure 2-2 for cable connections for testing.
