Welcome to
Azur Electronics

I am selling my complete Hewlett Packard 141T based Spectrum Analyser System, 20Hz to 18GHz, together with all the accessories. After completing various design projects, I need to downsize my Workshop and create some space.

This has taken me quite a few years to collect and many hours to refurbish and test the equipment, accessories and system. I would much prefer to sell the whole system to another electronics enthusiast, rather than break it up and sell it all item by item on eBay.

Complete HP 141T based Spectrum Analyser System and Accessories
The HP141T System is a popular and versatile Spectrum Analyser as it is hardware controlled. HP Operating and Service Manuals are available for download. This means that: complicated software menus are not used; what you see on the display has not been synthesised; and the comprehensive Manuals provide long term maintainability. Spare parts are also available.

Plus there is a lot of technical support available on the Forum at HP-Agilent-Keysight-equipment@groups.io
