  1. What is the AWG output voltage range, and can it directly drive an AOM driver?
    A: The output voltage should be kept at 1 VPP; it can directly drive the AOM.

  2. The start and stop frequencies of the sweep range.The minimum sweep time of the AWG—that is, the shortest possible sweep duration—affects the maximum pulse repetition rate.
    A: The start and stop frequencies may be anywhere within the bandwidth, which is DC–500 MHz.

  3. The minimum sweep time of the AWG—that is, the shortest possible sweep duration—affects the maximum pulse repetition rate.
    A: The AWG can load any waveform, with a minimum of 256 points and a maximum of 32,000 points, at a sampling rate of 6 GHz.

  4. Could you please provide a system architecture diagram for chirp DAS? I have seen the setup for pulse DAS on the official website, but not for chirp DAS. I am primarily seeking confirmation as to whether the existing pulse DAS system can be converted into a chirp DAS system (including the corresponding demodulation) simply by replacing the AOM with a 200 MHz model and switching from pulse to chirp mode.
    A: The DAS architecture remains the same; simply replace the AOM with a fixed 200 MHz frequency shift with one that sweeps over 200 MHz. We do not provide the specific demodulation algorithm; the acquisition card can capture the raw signal, but the user must implement the demodulation themselves.
