    Hi,

    I've got some attenuators that serve to attenuate RF signal of GHz frequency.

    Some of them don't have catalog number written on them.

    How can I know how many dBs each attenuates?
    Can I just measure the RF signal with and without them?

    Also, how can I tell if they're bi-directional?

    Thanks!

    Sounds right to me - provided you have the requisite equipment. Are these 50Ω devices? What about their throughput power rating?

    Measure the loss both ways - if its the same then they probably are bi-directional.
