    Is there a way to modify the VSG to use an external reference? If not, is there any way to reduce the drift?

    I do not see the phase noise specified in the manual. Is this information published somewhere?

    Found the phase noise. Seems within your spec. Drift looks well within spec but would really like to lock it to an external source.

    JoeQSmith,
    We do not have any provisions for locking the time base to an external source. There is a 24 MHz time base that could have been locked with an additional timebase PLL, but that would only get you within a few Hz, not a true lock, due to the resolution of the RF PLL.
    Any future vector signal generators we produce will have the ability to lock, but they will be significantly more expensive.
