octoBox quadAtten * DC to 6000 MHz Module with 4 programmable RF attenuators individually controllable via USB or Ethernet/PoE * 63 dB range * 0.5 dB step octoBox™ quadAtten module contains 4 individually programmable RF attenuators. quadAtten offers the best RF isolation on the market, making it suitable for highly controlled octoBox wireless testbed environment. While off-the-shelf attenuators have to be internally mounted due to inadequate isolation, octoBox quadAtten module mounts externally for easy access. Each of the 4 attenuators can be individually controlled via USB or Ethernet/PoE. APPLICATIONS Wi-Fi (802.11a/b/g/p/n/ac) and cellular (GSM, UMTS, LTE, FDD, TD-LTE and LTEAdvanced) testing Throughput vs. range measurements when used with the octoBox-MPE testbed RX sensitivity measurements Measurements under controlled signal and noise power settings octoBox quadAtten is an exceptionally well isolated high frequency programmable attenuator module with filtered USB and Ethernet interfaces. octoBox quadAtten module FEATURES & BENEFITS Frequency range: DC to 6000 MHz Dynamic range: 63 dB Step: 0.5 dB Insertion loss: 6 dB at 6000 MHz, typical 1 dB compression: 30 dBm IP3: 55 dBm Ethernet/PoE power and control interface USB power and control interface Provided PC software automates attenuation control and MIMO throughput vs. range measurements octoBox OB-THROUGHPUT script controls attenuators to produce throughput vs. range plots.
