OctoScope BOX-38: Semi-anechoic chamber

Key octoBox Building Block

Talk to us about this

Description

octoBox-38 semi-anechoic chamber is a key building block of the octoBox stackable wireless testbeds. octoBox features stable anechoic conditions for over the air (OTA) signal transmission inside. It supports a variety of filters for high speed data, video and power that enable you to control the devices inside without breaching the isolation of the octoBox.

The filters include gigabit Ethernet with POE (power over Ethernet), USB, HDMI and DC power. octoBox also supports the installation of a waveguide filter for feeding fiber optic or other non-conductive cables through to the devices inside. Ventilation is filtered via waveguide honeycomb filters.

Antenna kits, shelves and other accessories described in the octoBox Datasheet make octoBox easily adaptable for a variety of test configurations.
