KEN# W05
# Indicates the channel is asserted low.
Channel Qual 0:3 is not attached to the probe adapter by default. You may
connect this channel to other signals of interest.
CPU To Mictor Connections
To probe the microprocessor you will need to make connections between the
CPU and the Mictor pins of the P6434 Mass Termination Probe. Refer to the
P6434 Mass Termination Probe manual, Tektronix part number 070-9793-xx, for
more information on mechanical specifications. Tables 1–15 through 1–17 show
the CPU pin to Mictor pin connections.
Tektronix uses a counterclockwise pin assignment. Pin 1 is located at the top left,
and pin 2 is located directly below it. Pin 20 is located on the bottom right, and
pin 21 is located directly above it.
AMP uses an odd side-even side pin assignment. Pin-1 is located at the top left,
and pin 3 is located directly below it. Pin 2 is located on the top right, and pin 4
is located directly below it (see Figure 1–8).
NOTE . When designing Mictor connectors into your system under test, always
follow the Tektronix pin assignment.
