Unit powers on and all switches and knobs are functional. Includes probe and accessories. Appears to be functional, but has not been used in quite some time.
The Model 4815A RF Vector Impedance Meteris a general purpose, self-contained instrument for measuring complex impedance in a widevariety of laboratory applications, aswell asproductiontesting of circuits and components. The frequency range is 0.5 to 108 MHz; impedance magnitudeis measured in 9 ranges from 10 ohms100 Kohmsfull scale; and phase angle between 0° and 360° is indicated on two ranges.
An internalRFoscillator, 0.5 to 108MHzsupplies a test signal to the unknown impedance,12.6uaon the 10 ohm range,and 4uaon all otherranges. Provision is made for using an externalRFsource, particularly useful whenmeasuring quartzcrystals and other high Q devices.
the 4815A. The kit consists of adapters for probe to
BNC and Type N connectors, a probe socket for use
on circuit boards, a component mounting adapter,
probe holder, probe ground assembly and center pins.
Some of the accessories have been used over the years but it is mostly complete.
