    Hello,
    I need to generate the Chirp Modulation Signal for our LoRa based device conductive sensitivity verification test

    details attached for your reference.
    Is it possible using Arb mode od VSG25/60.
    Kindly advice

    Both devices have an Arb mode, but the VSG25 is limited to 2k symbols (very small buffer). It looks like these chirps are often clustered together in a sequence, and never wider than about a MHz, so the VSG60A would be the right choice, since its buffer is on the PC/laptop and can be very large if needed.

    Dear Sir,

    I am Sagar Mistry from System Level Solutions(India)Pvt Ltd.

    I need to generate the Chirp modulated signal for Lora Conductive Sensitivity testing purposes inside the lab using VSG25A.

    Please find the attached image for more reference regarding the specification of the chirp modulated signal need to generate using VSG25A.

    Request you to guide me regarding the necessary steps or configurations needed to perform in VSG25A.

    Hope to hear from you at the earliest.

    Thanks and Regards,

    Unfortunately, we are not familiar with the LoRa specification and do not have any resources to help you with your task.
