The 4400-8-94/5 from Spectrum Control is a 4-Channel Programmable Attenuator that operates from 0.1 to 8 GHz. It provides an attenuation range from 0 to 94.5 dB in 0.5 dB steps and has an attenuation switching time of 100 ns. The attenuation channels can be operated independently or in a synchronized fashion where all attenuators change simultaneously. The attenuators have an insertion loss of less than 6.9 dB. The system requires a DC supply of 5 V (USB powered) and draws less than 200 mA.
The 4400-8-94/5 can be controlled using USB & Ethernet interfaces and has a programmable TTL trigger through the AUX port. Spectrum Control’s control software can also be used to operate this attenuator. The control software allows users to set up, control, and perform tests and measurements over a standard USB 2.0 communication interface. It is available in a RoHS-compliant module that measures 152.40 x 17.56 x 61.32 mm with SMA-female connectors and is ideal for use in automated test equipment (ATE), 3G/4G LTE/5G / DVB fading test simulation, MU-MIMO, WiMax, Wi-Fi testing, mobile handover, and traffic simulation test environment applications.
