6 Measure the DUT.

A triggered measurement and the uniform window selection produces a much more
accurate response at the low end of the frequency spectrum. The periodic chirp
provides more energy than random noise. It is a self-windowing signal that provides
exactly the same stimulus from one measurement average to the next. Consequently,
averaging is not required.
The analyzer’s source impedance is less than 5 ohms. If your DUT needs a specific
source impedance, insert the appropriate resistor in series with the source output.
