RF accessories are categorized encompassing many different accessories that work to improve and modify the signal quality of radio frequency (RF) systems. An example is the Modulation Break Down Test (MBDT), which is used to determine the amount of power that a communication device can handle before the signal breaks down. This allows a user to know the maximum power level a device can view before the signal becomes unreadable.

The MBDT is performed by sending a signal with a continuous RF wideband noise and a predefined step at its modulation. This signal then passes through the device under test, and echoed back to the device, where it is then recorded and observed. The device will begin to see data errors and signal deterioration when the power level reaches above the maximum absorbable power. The maximum power that a device is able to tolerate is often referred to as the point of Modulation Break Down.

The MBDT is applied mainly in the form of radio communication and data networking. The MBDT is used to determine the maximum power level allowable for a particular channel, before any signal break down occurs. This is mainly important as designers of radio communication systems must ensure that the signals are strong enough to be received, but not too strong, as signal break down or data errors could be confused as reliable information, thus leading to system failure.

In order to perform the MBDT, special testing equipment is used. The test set must be able to perform signal modulation on frequency, while performing noise power measurements. The test set must also be capable to send a signal through the device under test, and record the echoed RF signal. The test set should produce reliable results, as it is important to consider the MBDT as part of any communication system design.

The major factor that affects the readings obtained during the MBDT is the noise power. When the noise power is improved the data errors of the signal also gets reduced. Most of the noise in the signal is caused by the environment, such as background noise; however, the design of the transmitter and receiver, can also affect the signal quality. As such, designing communication systems requires a careful consideration of the modifications that need to be made in order to reduce the noise power.

The MBDT is an important part of communication system engineering. It is used to ensure that the signals being sent out are reliable and can be understood by the receiver. When designing a communication system, it is important to consider environmental factors, design of the system, and the MBDT results, as any of these can affect the signal transmission. This will ensure optimal results for the system.
