HP 4352S VCO/PLL Signal Test System, 10 MHz to 3 GHz

The HP 4352S is a simple and multifunctional signal test system for VCO/PLL evaluation and test. This system can provide both powerful analyzing capability for design evaluation in LAB and high speed measurement capability for production line test with 2 operating modes, "signal analyzer" and "VCO tester." The HP 4352S, which consists of the HP 4352B VCO/PLL Signal Analyzer and one of the Hewlett-Packard low-noise signal generators controlled by the HP 4352B, covers up to 3 GHz and can measure the main VCO/PLL parameters, RF power, frequency, phase noise, spectrum, frequency transient, DC consumption current and FM deviation that are essential to designing RF oscillators used in wireless communication equipment.

The HP 4352B provides VCO tuning characterizing capability while controlling the internal DC power supply, the low-noise DC control voltage source and the 1 kHz signal source. In addition, this system can make high-speed phase noise measurements, thanks to the dedicated firmware and "carrier lock multi-mode PLL" technology that enables the system to lock onto the carrier of the measured signal automatically. And the HP 4352B has excellent phase noise performance, such as -157 dBc/Hz at 1 MHz offset typically, so that this test system can make reliable and repeatable phase noise measurement up to 10 times faster than conventional method. Actually, it can measure 801 measurement points from 100 Hz to 10 MHz offset frequency in 7.4 seconds/sweep. Adding the HP 71707A Microwave Downconverter expands its frequency range up to 26 GHz. Besides the powerful phase noise measurement capability, the HP 4352S can measure frequency transient with 50 Hz frequency resolution and 12.5 micro seconds time resolution. The HP 4352S improves your VCO and PLL evaluation efficiency and testing productivity dramatically.
