P6434 Probe Instructions
Nonstandard Probe Channel Assignments (Not Recommended)
The 17 channels to which the module end connects on the logic analyzer cannot
be changed. When mapping signals from your target system to channels on the
logic analyzer, you must keep the probe section, clock, and/or qualifier channels
together as shown in Tables 1 and 2 on page 3.
Each probe connector has 43 pins; pins 39 through 43 are the five ground pins.
Pins 1, 2, 37, and 38 are unused, and it is recommended that they be connected
to ground.
The nonstandard pin assignment was previously used by Tektronix but is no
longer recommended due to incompatibility with other commercial CAD
packages (see Table 7 on page 24).
The pin assignment is counterclockwise with Pin 1 located at the top left, and
pin 2 located directly below it. Pin 20 is located on the bottom right, and pin 21
is located directly above it.

Tables 8 and 9 show the sections and channels and the P6434 probe pins to
which they connect. Tables 8 and 9 also comply with the labeling schemes
shown in Tables 1 and 2 on page 3, except for the 34 channel module on the Pin
38 side of the probe. The Mictor pin numbers are shown for reference only.
NOTE
. Table 2 on page 3 shows the labeling scheme for a 34 or 68 channel
module.
