/ˈælfəˌtɛstər/

Origin: Formed within English, by compounding. Etymons: alpha n., tester n.⁴

Etymology: < alpha n. + tester n.⁴; in sense 1 with allusion to α as a symbol for current gain in a transistor; in sense 2 after alpha test n. Compare later alpha-test v.

1. Electronics. An instrument for ascertaining the ratio of the change in collector current to the corresponding change in emitter current in a transistor in a common-base configuration (the common-base current gain, symbol α). Now disused.
