Probe power

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

• The 513 provides +225VDC, +6.3VDC, and a variable supply producing +15VDC to +150VDC.

• The 517 and 128 provide +120VDC and +6.3VDC.

• The 3S1 provides +100VDC and -12.2VDC.

• The 4S1 provides +100VDC, -12.6VDC, and -25.2VDC.

• 7000-series scopes provide +15VDC, +5VDC, and -15VDC.

• 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.
