HMC-C200 DRO vibration sensitivity graph

Hi

I am not that familiar with vibration sensitivity, but I am trying to make sense of this graph that is given in the datasheet for the HMC-C200 DRO:

Can somebody please explain to me what this means? If the y-axis units were /G it would have made sense to me. As far as I know, /G is the usual unit for vibration sensitivity, and then I could calculate the phase noise of the device under specific vibration conditions. The unit g2/Hz used in this graph usually refers to power spectral density of vibration, but then the graph does not make any sense to me.

Any help would be appreciated, thanks.

  • good news and bad news.

    good news is that we have discussed this back and forth a few times and we have come to realize that you are right!

    the measured data should be in 1/g.

    Bad news, is that now we have to change the datasheet.

    thank you for calling us out on this and forcing us to unravel this internally.

    we at ADI are always learning and always improving.
