As the circular area is limited in space and for ground
reasons, as far as the signal lines are concerned, you have
to decide either for digital only or analog only signal lines
within a single group/segment each. Note, that you can
only have analog signal lines in some of the groups
depending on your test system configuration and your test
head filling (see“Test System Configuration” on page 70).
For the pogo pad assignment of the segments see the
description of the prob card in “Probe Card-Pogo Pad
Assignment” on page 107.
To know, which group connects to which card cage in the
test head see “DUT Board Mechanical Considerations” on
page 61.
