Resources & Application Notes Get more out of your RF test chamber.
Application notes from the bench on how RF shielded test enclosures actually work — how to spec one, how to get clean data through filtered I/O, and how to keep your shielding tight from sub-GHz all the way to 28 GHz.

Taking the Mystery Out of RF Wireless Testing
Start here. Why you need an RF test chamber at all, what one does, and how it fits into wireless testing — no prior shielding background assumed.

How to Select & Configure an RF Shielded Test Enclosure
Sizing, isolation, and how you'll connect to the device inside — the decisions that lock in before you ever request a quote.

Measuring & Verifying Shielding Isolation
How to test the test chamber — and exactly how 'tight' it has to be to actually shield. Verify your enclosure instead of trusting the spec sheet.

Using an RF Shielded Test Enclosure at Low RF Frequencies
Using the chamber from 10 kHz to 30 MHz: electric fields are stopped at any frequency, magnetic isolation holds full spec down to ~60 kHz — the physics, the numbers, and the steel-wall option.

Inside the Phone Crackers: How Forensic Extraction Tools Work
There's no secret backdoor — GrayKey and Cellebrite grind in on device state. Why BFU vs. AFU decides everything, why the 72-hour inactivity reboot changed the game, and why the forensics bench has to be RF-quiet.
Filtered I/O — getting data in and out
Every connector breaks the shield. Here's how to break it without losing your data or your isolation.

Understanding Data Signals Through Filtered I/O Connectors
Filtering keeps RF out — but it can also block the data you're trying to pass. Here's the conundrum, and how to get your signal through clean.

SuperSpeed data lands in the same band as the RF you're shielding out. What that means for cable lengths, connected devices, and the pitfalls to avoid.

The Effect of Adding Multiple I/O Filters
Every connector you add is another hole in the wall. Why more filtered interfaces can quietly degrade total isolation — and where the limit is.

Why Filtered I/O? What One Unfiltered Cable Does
The hole isn't the problem — the wire is. A conductor has no cutoff frequency, so one unfiltered cable drags a −100 dB enclosure down to −40. Why the whole filter category exists.
