81180B

Keysight Technologies (Agilent HP)Arbitrary

The Keysight (formerly Agilent) 81180B is a high-performance 4.6 GSa/s Arbitrary Waveform Generator designed for applications demanding extreme speed, high bandwidth, and exceptional signal fidelity. Featuring 12-bit vertical resolution, two phase-coherent channels, and up to 2 GHz of I/Q modulation bandwidth, the 81180B offers three software-selectable output amplifiers to optimize signals for direct RF, I/Q, or low-overshoot time-domain applications.
