1.2. Key Features
The RWC7100A RF shielding enclosure offers excellent shielding effectiveness of over 100dB within a wide operating
frequency range of 400MHz to 6400MHz, so that the effects of external interference are reduced to a minimum.
In all interior workspaces, absorber material is attached in order to minimize RF reflections.
Users can utilize the three I/O panels differently depending on the purpose of use, and can order a standard I/O panel
(Module) or a separate customization panel.
To maintain lasting shielding effectiveness, users can order additional EMI gaskets and easily replace them when
necessary.
There are many kinds of wireless standards in various industries that require a strict level of shielding effectiveness.
In particular, this product is suitable for measuring radiation of various DUTs (devices under test) in development,
production line and QC applications where high accuracy is required as shown below.
LTE, NB-IoT devices (700MHz, 2-6GHz)
LoRa, Sigfox devices (400MHz, 900MHz, 2.4GHz)
WiFi devices (2.4GHz, 5.8-6.2GHz)
Bluetooth devices (2.4GHz)
GNSS devices(1.2-1.6GHz)

• Refrain from using this equipment in a place subject to much vibration, direct sunlight, outdoor and where
the ground is not flat.
• If this product is not used for a long time, store it in a dry place away from direct sunlight, covered with vinyl or
placed in a cardboard box.
• If this product is left with the lid closed for a long time, the performance of the shield gasket may deteriorate.
Before using it again, be sure to open the lid and keep it open for at least one day, then check the shielding
effectiveness.

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.

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)
