USB Programmable Attenuator | 50 MHz–8 GHz, 90 dB, 0.25 dB Step
Model: AT10008B-90-U-MBT
The AT10008B-90-U USB Programmable Attenuator provides precise, programmable RF attenuation from 50 MHz to 8 GHz with a wide 0 to 90 dB attenuation range and fine 0.25 dB steps. Its compact USB-controlled design is well suited for automated RF testing, signal-level control, laboratory setups, production test systems, and RF development.
Built-in insertion-loss compensation helps the actual attenuation match the selected value, while the USB Type-C interface supports both GUI and API control for convenient manual or automated operation.
