Product Overview

Latest-generation large 2D-turntable RF chamber — automated TR-398 ready

Large 2D-turntable RF chamber, latest revision.

The CT840c is the newest revision of our flagship large-format chamber (CT840a / CT840b). Built around a programmable 2D turntable with ≥70 dB RF isolation, it's the de-facto chamber for automated TR-398, Rate-vs-Range and Rate-vs-Orientation testing. Comes with antenna mounts, LED lighting, an internal camera and the usual full set of filtered interfaces. The turntable, fan and door / light switches are controllable directly from LANforge for fully unattended test runs.

/// 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 ≈ 1092 × 900 × 940 mm.
  • Inside dimensions ≈ 890 × 660 × 520 mm — accommodates large enterprise APs and reference clients.
  • Approximate weight: 91 kg (200 lb).
  • API-controlled fan; door and light switches with API hooks.
