Measurement Guide for Reverberation Chambers

This page summarizes practical measurement guidance for MpyLab in mode-stirred (reverberation) chamber setups.

Overview

MpyLab integrates device control, acquisition, and evaluation in one Python runtime. Typical measurements are executed by a small measurement script plus one configuration file.

Recommended project layout per measurement campaign:

  • one dedicated folder for the measurement script and configuration

  • optional .dot file describing the measurement graph

  • autosave/output files generated by the runtime

Measurement runtime

A measurement run creates an MSC object, either from scratch or from persisted state (pickle). The runtime handles:

  • instrument communication

  • execution of measurement routines

  • evaluation routines

  • autosave and persistence of intermediate state

Persisting the state allows long-running measurements to resume from previous checkpoints.

Measurement graph (DOT)

The setup topology (instruments, cables, couplers, attenuators, paths) is defined as a graph in a .dot file. This graph is used by the runtime to resolve signal paths and evaluate measured quantities.

The DOT parser and grammar references are documented separately:
