The A3A1 Master Trigger Generator Card can produce trigger pulses at PRFs of which values?

The A3A1 Master Trigger Generator Card can produce trigger pulses at PRFs of which values?

• A. 300, 500, 900, 1100 Hz
• B. 600, 700, 800, 1000 Hz
• C. 200, 400, 600, 800 Hz
• D. 750, 850, 950, 1050 Hz

Answer: (B)

Pulse repetition frequency (PRF) is how often the trigger generator emits a pulse each second. The A3A1 Master Trigger Generator Card is built with a timing network that provides four discrete PRF settings, specifically 600, 700, 800, and 1000 Hz. These are the values the device is designed to produce, reflecting its internal divider ratios and timing limits. The other sets of PRFs propose frequencies outside this supported list or would require division options the card does not offer, so they don’t match how the card operates. In radar testing, using the correct PRF ensures the test pulses align with the intended scenario and avoid timing issues like missed pulses or aliasing.
