Operators can use this tab to change the Radar's STANDARD FREQUENCY even while the Radar is Radiating.

• A. False
• B. True
• C. Not allowed
• D. Ambiguous

Answer: (A)

In radar operation, critical RF settings like the STANDARD FREQUENCY are kept fixed during transmission to protect signal integrity and equipment stability. The transmitter’s frequency reference is tightly controlled, and changing it while the radar is radiating would detune the RF chain, cause a sudden frequency jump, and disrupt the coherence of the pulse and the processing that relies on a stable reference. This can degrade range and Doppler measurements and even create harmful interference or regulatory issues. To prevent these problems, the system typically disables the frequency-change option when the radar is active, requiring the radar to be in standby or off before making adjustments. So, you can’t change the STANDARD FREQUENCY while the radar is radiating, which is why the statement is false.
