The '''Tekprobe BNC'''interface is used in 1990s Tektronix equipment to interface active probes to oscilloscopes. | The '''Tekprobe BNC''' interface was introduced in 1986 and is widely used in 1990s Tektronix equipment to interface active probes (e.g. the [[P6243]]) to oscilloscopes. | ||
It is a downward-compatible successor to the [[BNC connector with readout ring]] used in earlier instruments like the [[7000 series scopes]]. | |||
It consists of a plain [[BNC connector]] that allows traditional BNC based connections such as from passive probes. | It consists of a plain [[BNC connector]] that allows traditional BNC based connections such as from passive probes. (See [[Patent US 4708661A]].) | ||

simple resistive readout pins | The two larger pad areas match the simple [[BNC connector with readout ring|resistive readout pins]], with division factors encoded as resistance to ground, although TekProbe BNC-era instruments accept values that earlier instruments did not. | ||
The smaller pads carry +15 V, +5 V, −5 V and −15 V power, an offset voltage (-1 V to +1 V) supplied and controlled by the mainframe, and a clock/data signal pair for serial communication between the mainframe and "smart" probes. | |||
