Abstract

1,116,730. Attenuators. TEKTRONIX, Inc. 2 Nov., 1966 [19 Nov., 1965], No. 49125/66. Heading H3U. An attenuator having input terminals 10, 12, attenuator sections 3 . . . 6 and ganged switch sections 16, 18, 20, 22 consisting of contacts 14, 26, 30, 32 movable through positions I to XI is characterized by a shunt connection 60 extending between switch sections 16 and 22. This shunt connection, by shorting the switch sections, reduces the undesired input capacitance of the attenuator by about 50% whenever the attenuator is switched into any one of the positions I to III which involve no attenuation. The attenuator sections 3 . . . 6 are described with reference to Figs. 3-6 (not shown).
