The Tektronix 6451 is an 8 channel active logic probe designed for use with the 7D01, 7D02, WR501, 308, 318, and 338. It presents 9 balanced signals back to the input section of the analyzer; 8 channels, plus a 9th used either for the clock or as a qualifier. It has the ability to set 3 different threshold voltages, channels 1-4, 5-8, and the 9th (called 'C' in the manual). The only active components are two custom hybrid pre-amp/comparator modules.
