The '''Tektronix P6451''' is an 8+1 channel active logic probe designed for use with the [[7D01]], [[7D02]], [[DL502]], [[LA501A]], [[WR501]], [[308]], [[318]], [[338]], and [[8550]]. | |||
It presents nine differential ECL signals back to the input section of the analyzer − 8 data channels, plus a 9<sup>th</sup> channel that is used either as a clock or as a qualifier. | |||

The P6451 has the ability to set different threshold voltages for each of three channel groups − 1-4, 5-8, and the 9th (called 'C' in the manual). | The P6451 has the ability to set different threshold voltages for each of three channel groups − 1-4, 5-8, and the 9th (called 'C' in the manual). | ||
The only active components are two custom hybrid pre-amp/comparator modules containing comparators with FET inputs and differential ECL outputs that can drive terminated 100 Ω lines.

It is also possible to use standard jumper wires with pins, sockets or clips on the other end for connecting inputs. | |||
There are two versions of the P6451: | |||
* Part No. 010-6451-02/-03 has a straight connector, and is intended for 7000-series and TM500 plug-ins (e.g.[[7D02]], [[SA501]]) and [[8550|8550 series]] development systems. | |||
* Part No. 010-6451-05/-07 has a 90° connector and is intended for 300 series analyzers (e.g. [[308]]). The -07 also has additional series resistance in the inputs for damping ringing caused by a lead set. | |||
[[P6458]] is a 4-channel version for the [[SA501]], which works with either model. | |||
