Segmented Memory The HP E1429 digitizer is capable of pre-arm and post-arm readings.
Pre-arm readings are taken after the digitizer is INITiated and before an arm
is received. Post-arm readings are taken after an arm is received. When
multiple reading sequences consist of pre- and post-arm readings, digitizer
memory is partioned into segments (Figure 3-9).
When the reading sequence consists of pre-arm and post-arm readings, the
number of segments is equal to the arm count. The maximum number of
segments (arm count) under these conditions is 128.
