HP 8564E

This HP 8564E is a used portable spectrum analyzer that covers a wide frequency range with excellent sensitivity, making it a workhorse for RF and microwave signal measurements in service and calibration environments. The unit has been maintained in working order and reflects normal cosmetic wear consistent with regular bench use, but it remains fully functional for field and lab diagnostics. It is well suited to technicians who need a dependable, proven platform for spectrum analysis tasks such as EMI troubleshooting, signal characterization, and general RF verification. The 8564E offers wide dynamic range and a synthesized local oscillator for accurate frequency measurements, along with a variety of built-in markers and trace functions that speed up everyday testing. Engineers and technicians use this analyzer to inspect harmonics, spurious signals, and modulation characteristics across communications and radar test setups. Its rugged HP build quality has made these units popular in calibration labs, educational settings, and depot repair shops where a trusted legacy analyzer is still valued. This listing is for the base analyzer unit only unless otherwise noted, and buyers should expect a previously owned instrument that has been powered on and functionally checked. It is a great option for labs looking to add a dependable used spectrum analyzer without the cost of new equipment, and it continues to be a common choice among test and measurement resellers and engineering teams working with legacy HP gear.
