For sale: a Hewlett-Packard 803A VHF Bridge, an early piece of HP RF laboratory equipment from the 1950s.
The 803A was designed for direct measurement of impedance magnitude and phase at VHF frequencies. It is a substantial, all-metal laboratory instrument with a built-in analogue meter, separate Phase and Magnitude controls, and connections for an external generator, detector and unknown load.
This is the kind of old HP equipment that is interesting both as functional test gear and as a historical laboratory collectible.
