The Tektronix 3T7 is a sampling timebase and pulser plug-in for 560-series scopes, introduced in 1971.

When used with a 3S7, a TDR system is formed.

The pulse is produced by a 21 mA, 1.5 pF tunnel diode, CR587, made by GE with Tektronix part number 152-0489-00.

The interface between the GR-874 connector and the printed circuit board is described in US Patent 3,426,311.

The 3T7 uses a CA3051 dual amplifier chip.
