Probe power
Many Tektronix instruments provide power for active probes. There have been several distinct versions of probe power.

The first Tektronix instrument to provide probe power was the 513. It provides +225VDC, +6.3VDC, and a variable supply producing +15VDC to +150VDC.
Second Generation
Third Generation
The 3S1 provides +100VDC and -12.2VDC.
Fourth Generation
7000-series scopes provide +15VDC, +5VDC, and -15VDC.
Fifth Generation
TekProbe is a proprietary probe-scope interface that combines signal and probe power and provides the scope with information about the what type of probe is connected.
