Product Overview
High-isolation large 2D-turntable RF chamber — ≥90 dB
Large 90+ dB RF chamber with 2D turntable.
The CT840b is the high-isolation analog of the CT840a — same
2D-turntable platform, ≥90 dB isolation. Full Wi-Fi sealing
even with all filters in use, making it the right pick for
DFS testing, certification work, and any scenario where the
last 20 dB of isolation matter.
Optional 3D positioner upgrade for full antenna sphere coverage.


CT840b
/// Software Features
RF & Network Interfaces
- •16+ filtered SMA ports (32 on the larger 'b' chambers).
- •3× filtered 10 GbE Ethernet pass-throughs per chamber.
- •USB-A 3.0, USB-A 2.0 (optional) and USB-C pass-throughs.
- •Optional 4K HDMI, RF Coax (Type-F) and FC fiber filtered ports.
- •Universal A/C power strip inside every chamber.
- •Optional DC-jack pass-through for chamber-internal power.
Frequency & Isolation
- •Designed for 800 MHz – 8 GHz operation, optimised for the 2-6 GHz Wi-Fi range.
- •'a'-series: ≥70 dB RF isolation (most affordable; great for everyday Wi-Fi work).
- •'ss' stack chambers: ≥80 dB RF isolation (mid-tier).
- •'b'-series: ≥90 dB RF isolation (full Wi-Fi isolation even with all RF filters in use).
- •RF-absorbing internal lining: ≥4.5 dB at 2.4 GHz, ≥10 dB at 5 GHz on 'a' models; ≥18 dB across 1.3-18 GHz on 'b' models.
Automation & Integration
- •Programmable 2D turntable (and 3D positioner option) on larger chambers — driven directly from LANforge.
- •API-controlled fan and door / light switches on supported models.
- •Integrated LED lighting and an internal camera on Large and Stack chambers.
- •Antenna mounts and high-gain directional antennas on Large and Stack chambers.
- •Front-loading doors with stack-friendly form factors.
/// Hardware Specifications
