2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. If you are using a test clip, touch any of the
ground pins on the clip to discharge stored static electricity from it.
CAUTION.
Failure to place the SUT on a horizontal surface before connecting the
test clip might permanently damage the pins on the microprocessor.
3. Place the SUT on a horizontal static-free surface.
4. Use Table 1–2 to connect the channel probes to R3051, R3052 and R3081
signal pins on the test clip or in the SUT.
Use leadsets to connect at least one ground lead from each channel probe and
the ground lead from each clock probe to ground pins on your test clip.
NOTE
. Since the probe adapter multiplexes address A31-A4 and data D31-D4 (as
the A_D31-A_D4 signals), the D3:7-0, D2:7-0, D1:7-0 and D0:7-4 channel
probes do not need to be connected.
These channels are not considered to be extra channels, even though they are not
connected. Do not use them to make connections to other signals in your SUT.
