Product Overview

Latest-generation medium RF chamber — ≥70 dB isolation in a desk-top footprint

Latest revision of the medium-sized 70+ dB RF chamber.

The CT820c is the latest revision of our medium-sized affordable RF enclosure family (CT820a / CT820a-hf / CT822a). Sized to fit most APs, Wi-Fi devices and instrument tools on a typical bench, with ≥70 dB of RF isolation across 800 MHz – 8 GHz. Comes with a full set of filtered interfaces (SMA, 10 GbE, USB, optional HDMI / coax / fiber) and a universal A/C power strip inside. Engineered for daily Wi-Fi 6E / Wi-Fi 7 testing where chamber repeatability matters more than carrier-grade isolation.

/// 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 ≈ 550 × 650 × 535 mm (matches the 'a' generation footprint).
  • Inside dimensions ≈ 480 × 490 × 480 mm — fits all common APs and most laptops.
  • Approximate weight: 30 kg (66 lb).
