You don't.  The modulation is applied to the UHF clock source the
machine uses to generate its bus clocks.  At these frequencies 10%
modulation depth will result in perhaps a few hundred nanoseconds in
uncertainty in the pulse position.  This uncertainty is not magified as
the clock is divided down.

More like 200 nsec.

So are you by standing there giving off thermal radiation.
