Description
HI up for sale is this General Radio Output Power Meter 1840-A. It measures audio-frequency power into any desired load, it also measures:Power output of Oscillators, Amplifiers, Preamplifiers, Transformers, Transducers, and Low-Frequency lines.
Output impedance, by adjustment of the load to yield maximum power indication.
Frequency-response characteristics of amplifiers, transformers, and other audio-frequency devices
This instrument is basically a multi-tapped audio-frequency transformer with a fixed secondary load. Its two front-panel switches connect eight identical primary windings and six secondary taps in various combinations to provide a total of 48 different primary impedances.
The maximum power rating can be extended for any given impedance with the use of simple T-network attenuator, design data for which are supplied with the instrument.Despite some cosmetic wear, it still appears to be in good condition (although it is NOT tested). Thanks for looking!
