<Admonition title="Important" type="danger">
Please note that the simulation is done using a noise model generated from system snapshots obtained in the past (sometimes a few years ago) and the results are not representative of the latest behaviours of the real quantum system which the fake backend is mimicking. If you want to run noisy simulations to compare with the real quantum system, you should use the `qiskit_aer` library. After installation, you can follow the steps below to generate a simulator that mimics a real quantum system with the latest calibration results.

If we want these to be text based, we need to save the output in a .. code:: text block. But I think the image is fine. This text is not very readable to a screen-reader, so the image with alt text will be more useful to non-sighted users.

Agreed! I like having an image there rather than the text much more too, but that's nice! TIL

<Admonition title="Note" type="note">
You need to call [`ALAPScheduleAnalysis`](qiskit_ibm_runtime.transpiler.passes.scheduling.ALAPScheduleAnalysis "qiskit_ibm_runtime.transpiler.passes.scheduling.ALAPScheduleAnalysis") before running dynamical decoupling to guarantee your circuit satisfies acquisition alignment constraints for dynamic circuit backends.
