4352B

The Keysight (Agilent HP) 4352B VCO/PLL Signal Analyzer is designed for evaluating voltage-controlled oscillators (VCOs) and phase-locked loops (PLLs) in both development and production environments. Operating from 10 MHz to 3 GHz, it functions as a signal analyzer and VCO tester to quickly measure RF power, frequency, tuning sensitivity, phase noise, and transients.
