State Acquisition Mode Field (State, State Compare,
and SPA only)
The State Acquisition Mode field lets you select which clocking mode to use
in the HP 16555A/D logic analyzers. For HP 16554A logic analyzers, 70 MHz
is the only clock speed available. The State Acquisition Mode field identifies
the channel width and memory depth of the selected acquisition mode. In
State Compare mode, some memory depth is used for information needed to
perform a comparison.
70 MHz/500K State (HP 16554A)
The State Acquisition Mode uses both pods in a pod pair. If time or state tags
are turned on, the total memory is split between data acquisition storage and
time or state tag storage. To maintain the full 500 K per channel depth, leave
one pod pair unassigned. State clock speed is 70 MHz.
100 MHz/1M State (HP 16555A)
100 MHz/2M State (HP 16555D)
The State Acquisition Mode uses both pods in a pod pair. If time or state tags
are turned on, the total memory is split between data acquisition storage and
time or state tag storage. To maintain the full 1M per channel depth, leave
one pod pair unassigned. State clock speed is 100 MHz.
