The duration of the modulator pulse is determined by which switch?

• A. Timing Switch
• B. Pulse Select
• C. Modulator Switch
• D. Range Switch

Answer: (B)

The duration of the modulator pulse is determined by the Pulse Select switch. This switch picks the preset pulse width that the modulator will produce on each trigger, so changing the selection directly changes how long the high-power pulse lasts. That duration affects the energy per pulse and overall radar performance. The other switches don’t set pulse width: the Timing Switch controls when pulses are generated relative to the timing sequence, the Range Switch selects the range window or gating, and the Modulator Switch simply turns the modulator on or off.
