The 4801-8-127 from Spectrum Control is a Solid-State Programmable Attenuator that operates from 0.3 to 8000 MHz. It is a cost-effective attenuator designed for customers who work with RF systems in challenging environments that require high performance. This attenuator consists of 8 channels and allows users to either independently control the attenuation in each channel or in a synchronized fashion, while maintaining excellent repeatability. It has an attenuation range of up to 127 dB in 0.25 dB step size. This solid-state attenuator has an insertion loss of less than 14.5 dB and a switching speed of 0.2 µs.
The 4801-8-127 can be remotely controlled via Spectrum Control’s control software over a standard USB 2.0 communication protocol or an Ethernet interface that supports protocols such as IP, UDP, TCP, TELNET and HTTP (via a web browser). This RoHS-compliant attenuator requires a DC supply of +5 V via USB and consumes 200 mA of current. It is available as a module that measures 243.84 x 83.22 x 17.55 mm and has SMA (female) connectors. This programmable attenuator is ideal for automated test equipment (ATE), 3G/4G LTE/5G/DVB fading test simulation, MU-MIMO/WiMAX/Wi-Fi testing, and mobile handover simulation test environments.
