Hewlett Packard 4352A

The HP 4352A is part of the entire HP 4325S system. The HP 4352S 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 measurement capability for production line test with 2 operating modes, “Signal Analyzer” and “VCO Tester” mode. The HP 4352S, which consists of the HP 4352B VCO/PLL Signal Analyzer and Hewlett-Packard low-noise signal generator controlled by the HP 4352B, covers up to 3 GHz and can measure the main VCO/PLL evaluation parameters, RF power, frequency, phase noise, spectrum, frequency transient, DC consumption current and FM deviation. In addition, the HP 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. When configured with the HP 43521A downconverter unit, the HP 4352S offers a dedicated and comprehensive VCO/PLL design and production measurement solution for manufacturers that must test at frequencies over 3 GHz. The enhanced HP 4352S is a complete system that offers a frequency range from 10MHz to 12.6GHz and is capable of measuring phase noise, RF power, transients, settling time, and many more parameters required for VCO/PLL evaluations. 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 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 with up to 10 times reduction in measurement time. Actually it can measure 801 measurement points from 100 Hz to 10 MHz offset in 7.4 seconds/sweep. 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. When the HP 71707A Microwave Downconverter is added to the standard system, the phase noise measurement can be performed up to 26.5GHz. The HP 4352S improves your VCO and PLL evaluation efficiency and testing productivity dramatically.
