3S6

Manuals – Specifications – Links – Pictures

The Tektronix 3S6 is a dual-trace sampling module for 560-series scopes, particularly the 568.

It interfaces with the sampling heads through a connector on its rear panel (using S-series sampling head extenders). Deflection factor, DC offset and polarity, as well as normal/smooth mode can be programmed externally by a controller such as the 240 / 241 Programmer. The 067-0584-99 Remote Programmer calibration fixture is available to do this manually during setup/calibration.

In a typical setup, the programming unit is connected to the 568 using a multi-conductor cable. The 568 routes those signals to the plug-ins.

Key Specifications

Deflection	2 mV/div to 200 mV/div, 1–2–5
DC offset	–1 V to +1 V
B channel delay	–5 ns to +5 ns
Programming	27 logic lines, true is ground or <2 V, false is open or >6 V
