P6451

The Tektronix P6451 is an 8+1 channel active logic probe designed for use with the 7D01, 7D02, LA501A, WR501, 308, 318, and 338. It presents nine balanced signals back to the input section of the analyzer − 8 data channels, plus a 9^th 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 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. The instrument input would contain differential ECL receivers like the 10115 or 10216.

Input lead sets:

• 012-0747-00 - standard 10-wire 25 cm with pluggable probe tips
• 012-0655-01 - ten individual 40 cm leads
• 012-0655-02 - ten individual 8 cm leads
• 012-0670-00 - ten individual 16 cm leads
• 012-0800-00 - 10-wire 10 cm

Part numbers for the P6451 are 010-6451-03 (straight connector) or 010-6451-05 (90° connector e.g. for 308).
