About the measurement method of radiation emission

I have a question about how to measure radiation emissions.

Tittle is『Optimizing EMI in Switching Regulators for Consumer and RF-Sensitive Applications』

How do you measure the EMI Tests shown in Fig. 8 and Fig. 9?

Is the board put in a case for measurement?

Best regard.
