Which card produces pulses that are 50 ns wide?

• A. Sweep Generator card
• B. Master Trigger Generator card
• C. Range Gate card
• D. Pulse Shaper card

Answer: (B)

In radar timing, syncing all modules hinges on a pulse with a precisely defined width. The Master Trigger Generator is built to output a master timing pulse with fixed, known dimensions, such as 50 nanoseconds, so every subsystem can synchronize to the same event.

The Sweep Generator creates a signal that changes over time to drive displays or measurement sweeps, not a fixed-width trigger for coordination. The Range Gate controls when the receiver is active within a chosen range window, focusing on gating rather than delivering a standard trigger pulse. The Pulse Shaper adjusts the shape of a pulse but doesn’t inherently provide a fixed, nanosecond-scale width used for global synchronization.

So, the card that provides a 50 ns wide pulse is the Master Trigger Generator.
