Before installing the links in the field, it is recommended that you bench-test the links. A suggested setup

for basic bench testing is shown below:

When setting up the equipment for bench testing, note the following:

Each radio should be earthed at all times. The radio earth point should be connected to a protection earth.

In a bench setup, there should be 60 - 80 dB at up to 1 GHz of 50 ohm coaxial attenuation, capable of

handling the transmit power of +37 dBm (5 W) between the radios' antenna connectors.

If more than two radios are required in your bench setup, a multi-way splitter is required. The diagram

shows a two way splitter. This splitter should be 50 ohm coaxial up to 1 GHz and capable of handling the

transmit power of +37 dBm (5 W).

Use double-screened coaxial cable that is suitable for use up to 1 GHz at ≈ 1 metre.

CAUTION: Do not apply signals greater than +10 dBm to the antenna connection as they can damage the
