Probe leads and lead sets
Probe leads are configured into lead sets, which can probe 16 data channels with
ground, one clock channel, and a common ground. A 17-channel probe lead set
(E5383A) is shown in Figure 9.2, along with the replacement part numbers for individual
components in Figure 9.3.
Each probe lead is a 12-inch, twisted-pair cable connected to the probe cable at the
probe housing (see Figure 9.3). The probe tip includes a signal lead, a connector for a
ground lead, and the isolation network.
The signal and ground leads can be connected directly to the target system. This
requires installing 0.63 mm (0.025 inch) square pins, or round pins with a diameter of
between 0.66 mm (0.026 inch) and 0.84 mm (0.033 inch) directly on the board. An IC
test clip can also be used. The same specifications apply for the pin dimensions of the
test clip. (See Figure 9.6 for IC test clips available from commercial sources.)
