  • HMC778 Frequency Sweep Mode

    Hi

    I have a question about HMC778 from the customer.
    He wants to make the trigger at TRIG synchronize exactly with starting of frequency change.
    Then, do you have any timing specification between rising edge of TRIG and starting of frequency change?
    Is…
