−100 dB of RF isolation.

The hard part of feeding a USB-3, USB-C, 10G, or HDMI line through a shielded wall is that high-speed data and RF interference are, electrically, the same beast — a conventional low-pass filter would cut your data right along with the noise. On our patented high-speed interfaces, the design discriminates by signal mode instead: your differential data passes unfiltered, while the common-mode RF riding alongside it is low-pass filtered out — even when that interference sits right at your data frequency. (Our USB 2.0 and 1G Ethernet interfaces use straightforward low-pass filtering — the right tool for those data rates; the mode-selective design is what makes the high-speed lines possible.)

We don't drill the enclosure body for your configuration — your interfaces live on a flat I/O plate that we customize, install, and final-test in the exact setup you'll run. Two consequences: custom configurations ship in days instead of months, and when the next interface arrives, you swap a plate, not a chamber. Your enclosure doesn't become obsolete.

JRE Test builds on a line of engineering that kept solving the next problem instead of stopping at the first one. The category started here: founding engineer John Ramsey originated the operator-accessible RF shielded test enclosure — the hands-in design that lets you reach in and manipulate a device by hand while the shield holds — then kept extending it with the bare-arm sleeve, the high-performance shielded window, and the high-speed filtered interfaces. That's JRE patented technology, and the same engineers who carry it forward are the ones you reach when you spec your test.
