TEST ELECTRONICS’ RF Shielded Fixtures
Simple shielded fixture provides Isolation of -60dB@4GHz.

RF Enclosure provides Isolation of -90dB@4GHz.
Double shielding, shielded fixture inside an RF enclosure <-120dB@4GHz

Cost effective solutions to RF shielding and isolation problems.

TE2100 RF Shielded Fixture
Simple Low cost RF isolated Bed of Nails clamshell style circuit board test fixture. Provides isolation of -60dB @ 4GHz. This shield option may be added to any of our TE1X00 and TE2X00 series clamshell style fixtures and fixture kits. The shield is fabricated from industrial strength 1/16" aluminum and lined with RF absorbent foam then mounted onto the press plate with 4 standoffs for easy removal. The fixture is also lined with RF absorbent foam. Two tabs near the hinging mechanism which guide the sides of the RF shield to slice tightly along the sides of the fixture create a tight RF shield which provides superior RF isolation performance of -60dB @ 4GHz. For greater performance of -90dB @4 GHz, our standard off the shelf unshielded fixture can be placed in one of the recommended Ramsey Electronics enclosures shown below on this page. Double shielding should mathematically provide -150dB @ 4GHz. we were only able to verify -120dB @ 4GHz due to limitations in the equipment available at our local testing laboratory.

TE2100 Fixture Actuated
Shows the press plate closed and pressing the board against the test pins. Note the tight RF seal provided by the way the sheet metal overlaps and slides into place.

TE2100 Shield Removed
The RF shield is held in place by 4 standoffs and can be quickly removed with only 4 screws. This provides an easy way to inspect and make adjustments if necessary. In the unit pictured here, access holes were added to the shield to adjust the press downs. This is only done for lower frequency applications because the holes would sacrifice RF isolation performance in higher frequency fixtures.

TE2500 Back View
This view clearly shows the tabs on the RF shield which is the key design technique that allows the edges of the RF shield box to create the tight overlapping RF seal along the edges of the fixture providing an isolation performance of -60dB @ 4GHz

TE2500 Open View
Quick 3 step operation saves man hours:
  1. Open the fixture with a touch of the front panel mounted thumb lever latch.
  2. Place the board under test inside.
  3. Press the fixture closed until you hear the latch click and lock.

Your UUT is simultaneously placed inside the fixture and an isolated RF environment ready to run your test all in one simple time saving action!
