The Keysight PZ2121A is a high-speed precision source / measure unit (SMU) featuring best-in-industry narrow-pulse width, fast Digitizer Mode, and seamless current measurement ranging. It enables narrow-pulsed measurements and fast dynamic measurements with a wide dynamic range for a wide range of emerging applications such as vertical-cavity surface-emitting laser (VCSEL) optical devices, integrated circuit (IC) testing. In addition, its low measurement noise performance enables measurements with shorter aperture times, and its seamless current measurement ranging function enables a wide dynamic range and eliminates range change time, which improves test throughput.
