3B1

The Tektronix 3B1 is a timebase plug-in for 560-series scopes. The calibrated sweep rates go from 1 sec/div to 500 nsec/div. There is a switch that enables 5X horizontal magnification, which makes the fastest sweep 100 nsec/div. The 3B1 has a delayed sweep and a regular sweep. The 3B1 uses vacuum tubes, bipolar junction transistors, and tunnel diodes.
