HP 8340A

This used HP 8340A synthesized sweeper is a microwave signal generator covering from 10 MHz up to 26.5 GHz, built for high accuracy swept and CW signal generation in demanding test environments. It has served in labs performing component characterization, filter and amplifier testing, and general microwave network analysis, and it is offered here in working condition for continued laboratory or production use. The 8340A established a strong reputation for stability and repeatability that made it a mainstay of microwave test benches for many years. Engineers use this sweeper to provide precise stimulus signals when characterizing devices under test with spectrum analyzers, power meters, or network analyzers. Its synthesized architecture delivers the frequency accuracy and low phase noise required for sensitive measurements, while its sweep capabilities support fast, repeatable testing across wide frequency spans. The unit's rugged HP construction has allowed many of these instruments to remain in active service decades after their original manufacture. This signal source is well suited for RF and microwave engineering labs, calibration departments, and manufacturers of high frequency components who need a dependable swept source without the expense of a brand new synthesizer. Some cosmetic wear consistent with age and use should be expected, but the core synthesis and sweep functions remain the primary value of this instrument. It is a solid choice for buyers seeking proven microwave signal generation performance at an accessible price.
