What does the Interference Blanker provide?

• A. Provides a blanking signal to connected receivers whenever the main terminal unit is transmitting
• B. Encrypts data during transmission
• C. Loads crypto keys automatically
• D. Measures signal strength of Link 16

Answer: (A)

Interference management during transmission is being tested here. The Interference Blanker provides a blanking signal to connected receivers whenever the main terminal unit is transmitting. This signal tells those receivers to mute or blank their inputs during the MTU’s transmit window, preventing the transmitter’s energy from causing interference or desense in the receiving path. The other options describe encryption, crypto-key handling, or signal‑strength measurement, which are separate functions and not what the Interference Blanker does.
