 The '''Tektronix 7A12''' is a 120 MHz dual-trace vertical plug-in for [[7000-series scopes]].
-It was designed by [[Roy Hayes]] (who also designed the [[3A3]] before leaving for HP Loveland in Jan 1971).
-The Evaluation Engineer for the 7A12 was [[Peter Starič]], co-author of the
-book "Wideband Amplifiers" with Erik Margan.
-The 7A12 has relays in the signal path for the input attenuators.
-The relays are controlled by logic in the 7A12, which is controlled by switches on the front panel of the 7A12.
-The 7A12 uses the [[155-0032-00]] as a gain stage and the [[155-0022-00]] for channel switching.
+Switches on the front panel control [[miniature relays]] in the signal path, such as those selecting input attenuators, through logic circuits.
