On-site measurement of radiated emission

Here is an example of on-site measurement of radiated emission at a site without a shield environment.

Application

• This is on-site measurement system of radiated emission for pre-compliance.
• This is very convenient for measuring such large EUT as difficult to bring to a test site.
• This is excellent in cost performance because of a combination of our products.
• This can easily measure outdoors because of handy type measuring instruments.
• The near field probes can also be used to find radiated sources.

Solution

• 
• [Measurement flow]
  1. Measure environmental noise at EUT power off.
  2. Measure the noise at EUT power on.
  3. Subtract ① from ② and take out only noise from the EUT.
