GPIO Control

R2026b
Configure GPIO pins for automatic transmit/receive or manual control

Use Wireless Testbench™ radio objects to configure automatic transmit/receive (ATR) behavior or manual GPIO control on your NI™ USRP™ radio. By configuring ATR behavior, external hardware such as RF switches, LNAs, PAs, or trigger inputs can automatically respond to radio transmit, receive, idle, and full‑duplex states.
