Période

early 1970s+

Canada

An American made instrument of the early 1970's used at DREA (Defence Research Establishment Atlantic), now DRDC Atlantic (Defence R & D Canada - Atlantic), a department of National Defence. Canada's Defence Research Board was founded in 1940 to provide scientific support to all three armed services; in 1967 the Atlantic component in Dartmouth, NS became DREA. The current mandate of DRDC Atlantic is to conduct research and development in underwater and marine military technology for Canada's Navy and Air Force (Ref. 3). This instrument was put into operation 1971.01.10 as part of the Equipment Pool inventory at the Dartmouth facility and was primarily used by electrical engineers (Ref. 1).

Fonction

An instrument used to measure impedance, displaying impedance magnitude, impedance phase & frequency.

Technique

This instrument was marketed by HP as providing the design engineer with an easy-to-use , one-instrument method for checking impedance of components & circuits. Impedance of components, complex networks, & other tho-terminal devices was measured by connecting the device to the HP impedance meter, selecting the desired test frequency, & adjusting the impedance range switch. Both impedance magnitude in ohms & phases in degrees were read directly (Ref. 2).
