Using a bias tee and sampling tee, you can inject specific
frequency, measureable "noise" into the power supply connection.
This will allow you to make measurements as you would
with simulations.
If you're not familiar with them, a bias tee combines
DC signals and AC signals. You can supply your DC supply
on one port, your AC-noise on the second port, and the
third port containing both the AC and DC signals goes
to your device. This will allow you to inject specific
frequency noise into your device.
A sampling tee simply strips off a small portion of the
signal from a coax line to allow to to measure its amplitude.
By placing a sampling tee after the bias tee, you can
measure the AC and DC signals going into your device.
Both types of tees can be purchased from Agilent, Picosecond Pulse
Labs, and others....
Hope this helps,
Pat
