Page 29 While all of the modules in a merged set can use their clock inputs independently if needed, it must be remembered that there are a maximum of four clock inputs on a 136 channel wide module. P6960 and P6980 High-Density Logic Analyzer Probes Instruction Manual...
Page 30 To see the importance of this reminder we will once again use a microprocessor system as an example. Tektronix logic analyzer processor has a 32 bit address bus and a 64 bit data bus. The data bus is split into four 16 bit subgroups that have independent source synchronous clocks.

Page 37 Reference Physical Attachment Requirements for the P6960 and P6980 Probes. The P6960 High-Density Probe and P6980 High-Density Differential Probe interconnects are designed to accommodate PCB thickness ranging from 1.27 mm to 6.35 mm (0.050 in to 0.250 in). To accommodate this range, there are two wire lengths in the design: H For board thicknesses of 0.050 in to 0.120 in, use the standard wire that is...
Page 38 Figure 16: High-Density and High-Density Differential probe load model The differential load for the P6960 clock input and the P6980 probe can be modeled by attaching the single line model to each side (+ and - -) of the differential signal. The + and - - sides of the differential signal are well insulated in the probe head up to and including the differential input stage.
Page 39 NOTE. Tektronix recommends using immersion gold surface finish for best performance. Tektronix also recommends that the probe attachment holes float or remain unconnected to a ground plane. This prevents overheating the ground plane and promotes quicker soldering of the retention posts to your PCB. The probe retention posts are designed to allow you to solder the retention posts from either side of your PCB.
