Chapter 1: Agilent Technologies 16712A 128K Sample Logic Analyzer
The Sampling Tab
Setting the Acquisition Mode
The measurement type affects all other areas of the logic analyzer
setup. It is set under the
Sampling
tab.
If you want the logic analyzer to sample data according to the target
system's clock, select
State
. Each time the clock signal becomes valid,
the analyzer will sample data from the system under test.
If you want the logic analyzer to sample the target system
independently of its clock, select
Timing
. Since in timing mode the
analyzer is clocked by a signal that is not related to the system under
test, timing measurements capture traces of electrical activity over
time. The Agilent Technologies 16712A logic analyzer can be split into
two analyzers, but only one of them may be a timing analyzer.
State Mode
and
Timing Mode
offer different options for the
acquisition mode field in the top left corner under Controls. The
acquisition mode affects the channel width, memory depth, and sample
rate.

Performing Clock Setup (State only)
When you select State Mode, the Clock Setup area appears under the
State Mode Controls in
Sampling
. The Clock Setup contains three
controls and a display area. The clocks you specify here control when
the analyzer samples your data. Ideally, the logic analyzer's state clock
setup should be identical to the target system's clock. Differences
could result in invalid data.
