Test Sequencing - QuadTech 7600 B Instruction Manual

2.6.4.2 Test Sequencing

The 7600 is capable of performing a sequence measurement containing up to six
different test steps. Different measurement parameters and conditions can be defined
for each test in the sequence.
Test sequencing can be selected as Off, On or Edit.
parameters and test conditions to be changed for all six tests. It is important to note that
tests can only be enabled in sequence, for example, one can enable tests 1 through 3
but not tests 1 and 3 only, i.e. it is not possible to skip a test. For optimum measure speed
performance, whenever possible, set test conditions of test 1 to be the same as default
conditions, paragraph 2.5.2.

If Range Hold is turned ON and this is the "first" sequence measurement, for each test the
7600 automatically finds the correct range and completes a measurement (this range is
saved for all future measurements) for that sequence only. It is important that the first
part be "good" for the range hold to select the correct range. To repeat an auto range
selection, turn sequences off and then back on again (making the next measurement taken
the "first" sequence measurement).
Test conditions for each setup are selected as shown above except for the primary
parameter, secondary parameter and binning, these are selected on individual menus as
shown below. To change test conditions on any or all six tests select Prev Test or Next
Test to access test conditions for that test.
