The module supports both Continuous Wave (CW) operation and modulation modes. Modulation is compatible with Analog or TTL signals at frequencies from 0 to 30kHz, making it suitable for time-gated sensing, ranging, and synchronization with external instrumentation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply do I need, and is it included?\u003c\/h4\u003e\n\u003cp\u003eA: A matching AC\/DC power supply unit (PSU) is available in three form factors: a compact OEM type for system integration, a standard lab type, and an adjustable lab type for R\u0026amp;D use. All accept universal AC input (85–265V, 50\/60Hz).
