Applications
The HP 86242D, 86245A, and 86250D are RF plug-in modules designed for use with the HP 8620C Sweep Oscillator mainframe — part of Hewlett-Packard's Cal Lab series of precision microwave test instruments from the late 1970s. These plug-ins provide the frequency-generation capability of the sweep oscillator system, covering specific microwave frequency bands with calibrated output power and frequency accuracy. The 8620C series was widely used in RF and microwave laboratories, calibration facilities, and production test environments for tasks such as swept frequency response measurements, gain and flatness testing of amplifiers and filters, and antenna range testing. This manual provides the full operating procedures, performance verification tests, alignment and adjustment procedures, and illustrated parts data needed to operate and service these plug-ins to HP factory standards. It remains an essential reference for anyone maintaining, repairing, or calibrating 86242D, 86245A, or 86250D plug-ins today.
This HP 86242D / 86245A / 86250D RF Plug-In Operating and Service Manual (part number 86245-90001) has been inspected and is in good used condition. The cover shows light shelf wear consistent with age — a handwritten inventory notation is visible on the front cover — but the binding is intact, all pages are present and legible, and the printed diagrams, tables, and schematics throughout are clean and clear. This is the original April 1978 Hewlett-Packard printed edition. Please view our photo set and contact us if you have any questions.
