Probe power: Difference between revisions

Revision as of 12:10, 21 January 2019

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

The 513 provides +225 V, +6.3 V, and a variable supply producing +15 V to +150 V, on a 4-pin connector.
The 517 and 128 provide +120 V and +6.3 V for Type P500CF cathode-follower probes.
The 1S1, 3S1 and 3S76 provide +100 V and −12.2 V for Type P6032 cathode-follower probes.
The 4S1 provides +100 V, −12.6 V, and −25.2 V.
The N provides +100 V and 6.3V AC for Type P6025 cathode-follower probes.
The 015-0073-00 has a 3-pin probe power connector (Sealectro 55-850-0018-98(?)), the 454/454A a pair of these, providing +12.5 V and −12.5 V for probes P6045, 282, ...
7000-series scopes (not all models), 475, 485, the 1101 probe power supply, and the 2707 tracking generator provide +15 V, +5 V, and −15 V through a LEMO S-series connector.
TekProbe BNC, TekProbe SMA and TekConnect are proprietary probe-scope interfaces that combine signal and probe power as well as control (e.g. offset voltage), and provide the scope with information about the type of probe connected.
