Yes,
Not only will the LISN have poor performance above 100 MHz, but the
CISPR voltage probe or a "down and dirty" series capacitance will have
trouble at these frequencies, although they will all work well at lower
frequencies. Many of the other suggestions from members on this subject can
be used to measure higher frequencies.
As is invariably the case in this business, the "correct" answer
depends on the frequency range of concern and the problem actually trying
to be identified. Usually for the higher frequencies I use field probes
along the board or cables rather than contact, sometimes adding short wires
as "intentional unintentional" radiators.

Hi there - The AC LISN will have a very poor performance above about
100MHz don't you think??
