Principle

EMI shielding, of high importance in the electronics industry, measures the effectiveness of a material to protect signals from being disrupted by external electromagnetic signals, as well as preventing generated signals from interfering with surrounding components.

Capabilities

20KHz - 15.GHz

ASTM D4935
Repeated sweeps are made across the frequency range and averaged for both the shield and blank specimens
6" square sample or larger (minimum 4 required)
Testing temperatures (lab ambient)

Equipment

	Equipment Type	Information
	Custom fixture for 20KHz-1.5GHz	Frequency range is swept Shield is compared to blank Samples are modified to fit
	Copper Mountain TR-5048 VNA	Connects to fixture coaxially Utilizes TRVNA software
