Agilent/Keysight M8054A

The Keysight M8054A is a 32 GHz interference source module that generates repeatable, accurate level impairments for testing high-speed digital receivers in communication, radar, and electronic warfare applications. This 1-slot AXIe module delivers four differential output channels with adjustable bandwidth from 160 kHz to 32 GHz, supporting symbol rates up to 64 Gbaud and line coding formats including NRZ and PAM4. It integrates with Keysight's M8000 Series BER test solutions and the M8040A BERT for comprehensive receiver stress testing.
