The block generates a perturbation signal at this port. Typically, you inject the
perturbation from this port via a sum block, as shown in the following diagram.
- When the experiment is running (start/stop positive), the block generates
perturbation signals at this port. - When the experiment is not running (start/stop zero or negative), the signal at this
port is zero. In this state, the block has no effect on the plant.
Dependencies
To enable this port, in Output Signal Configuration, select perturbation only.

The signal at this port contains the data that the block collects during the frequency-
response estimation experiment, including the perturbation signal applied to the plant
and the measured plant response. Use this port when you want to log experiment data for
later use. For instance, you can conserve resources in a deployed environment by logging
the data and performing the estimation offline (see Estimation Mode). There are two
ways to access the frequency response experiment data.
