The Tektronix 3T7 is a sampling Timebase and Pulser Plug-in for 560-series scopes.
The 3T7 was 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.
