Cellular and personal-communications-services (PCS) telephone manufacturers strive for more-efficient manufacturing methods. This has intensified the competition among test-equipment manufacturers to provide instruments tailored for automated production test. As one of the fundamental elements of every RF automatic-test-equip-ment (ATE) system, frequency synthesizers are sprouting faster and simpler automation, higher test speeds, better phase-noise performance, and better maintainability, for the same price (or less) than their less-well-endowed predecessors. With the 68000 and 69000 families of frequency synthesizers, Anritsu (Morgan Hill, GA) addresses this market with no fewer than 42 discrete instrument models in three broad categories. Each instrument is configured to meet the performance needs of specific applications and budgets. The new 68C and 69B models add to these capabilities with improvements in phase noise, measurement speed, automation, and calibration.
