Template:Plugin Sidebar 2 The Tektronix 7B92 is a 500 MHz timebase plug-in for 7000-series scopes. It was introduced along with the 7904 mainframe in 1972.

The 7B92 uses a discrete trigger circuit containing tunnel diodes.

Up to serial number B069999, the 7B92A used a discrete trigger circuit. After that, the 7B92A used a 155-0061-00 trigger amplifier followed by a 155-0150-00 trigger detector.
