Product Overview

Integrated 4-chamber stack — ≥90 dB isolation, full Wi-Fi sealing

4-chamber integrated stack with 90+ dB isolation, 2D turntable.

The flagship of the stacked-chamber line: ≥90 dB RF isolation per chamber, full Wi-Fi sealing even with every filter in use. The right pick for DFS, certification work, and any test where stray Wi-Fi from the outside world cannot be allowed to leak in. Same 4-chamber layout (large DUT center with turntable, medium clients on top, instrument bay below) — pre-wired and LANforge- controlled. Optional 3D positioner upgrade.

/// 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

  • Welded steel construction with conductive RF gaskets and filtered penetrations.
  • Forced-air ventilation with filtered intake/exhaust to keep DUTs cool.
  • Universal A/C power strip inside the chamber.
  • Front-loading door with quick-release latches; stackable with matching chambers.
  • Customisable port configurations — tell us your DUT and we'll wire the chamber to match.
  • Outside dimensions: 1200 × 800 × 2300 mm (47.25 × 31.5 × 90.5 in).
  • Heavy-duty welded steel with double conductive gaskets.
  • ≥18 dB RF absorption across 1.3-18 GHz internal lining.
  • Castor base for rolling.
