HP 8595A

This used HP 8595A spectrum analyzer comes from the well regarded HP 8590 series and covers a frequency range extending to 6.5 GHz, making it suitable for a wide variety of RF and microwave measurement tasks. It has been used in production testing, field service, and calibration lab settings where its combination of accuracy and portability made it a workhorse instrument for years. The unit is offered in operational condition, ready to support ongoing test and measurement needs. Engineers rely on the 8595A for signal analysis work such as measuring spurious signals, evaluating amplifier gain and distortion, and verifying transmitter performance across a broad span. Its synthesized local oscillator delivers the frequency accuracy required for repeatable measurements, while the analyzer's dynamic range supports both low level noise floor measurements and strong signal analysis on the same bench. The instrument's straightforward front panel controls make it approachable for technicians moving between multiple pieces of legacy HP gear. This analyzer is well suited for labs, universities, and RF service organizations that need a dependable secondary or primary spectrum analyzer without the cost of new equipment. As with all used test gear, some cosmetic wear should be expected, but the underlying measurement performance remains a strong match for general purpose RF work. It is a practical choice for buyers seeking proven HP quality at a reasonable price point.
