Product Overview

Large 2D-turntable RF chamber — automated TR-398 testbed staple

Large 70+ dB RF chamber with programmable 2D turntable.

The CT840a is the long-running large-format 2D-turntable chamber — the workhorse behind countless TR-398 Issue 1/2/3 testbeds. ≥70 dB isolation, programmable turntable controlled directly from LANforge, and an internal LED + camera for remote observation. Stable, well-understood, and frequently in stock.

/// 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.
