The Agilent 4352B test system can evaluate the characteristics of VCOs and PLLs that are essential to designing local oscillators used in RF wireless communication equipment. This system can provide both powerful analyzing capability for design evaluation in LAB and high-speed measure-merit capability for production line test with 2 operating modes, “Signal Analyzer” and “VCO Tester” mode.
The Agilent 43525, which consists of the Agilent 4352B VCO/PLL Signal Analyzer and Hewlett-Packard low-noise signal generator controlled by the Agilent 4352B, covers up to 3 GHz and can measure the main VCO/PLL evaluation RF power, frequency, phase noise, spectrum, frequency transient, DC consumption current and FM deviation. In addition, the Agilent 4352B provides and controls the DC power supply, the low-noise DC control voltage source and the 1 kHz signal source necessary for VCO tuning characterizing. This system can make high-speed measurements thanks to the dedicated firmware and “carrier lock multi-mode PLL” technology for phase noise measurement that enables the system lock unto the carrier of the measured signal automatically.
In addition, the Agilent 4352B has excellent phase noise performance such as -157 dBc/Hz at 1 MHz offset typically, so that this test system can make reliable slid repeatable phase noise measurement. The 4352B can measure 801 measurement points from 100 Hz to 10 MHz offset in 7.4 seconds/sweep.
And adding the Agilent 71707A Microwave Down converter expands its frequency range up to 26 GHz. Besides the powerfull phase noise measurement capability, the Agilent 43525 can measure frequency transient with 50 Hz frequency resolution and 12.5 micro seconds time resolution.
