8-Channel Programmable Attenuator | 50 MHz–8 GHz, 90 dB, 0.25 dB Step

Model: AT80008B-90-UE-MBT The AT80008B-90-UE 8-Channel Programmable Attenuator provides precise, independent RF attenuation across 50 MHz to 8 GHz. With 8 channels, a wide 0 to 90 dB attenuation range, and fine 0.25 dB steps, it is well suited for multi-channel RF testing, automated test systems, signal-level control, production testing, and laboratory applications. Built-in insertion-loss compensation helps improve attenuation accuracy, while USB Type-C and Ethernet interfaces provide flexible control options. GUI and API support make the unit easy to integrate into both manual and automated RF test environments.
