Storing a Sequence
Sequences, unlike manual setups, are not stored between power cycles. When power cycling
the instrument, the mode will remain as Sequence mode, the sequence model will be empty
and require reloading from the setup menu.
Each sequenced model can be stored and recalled to and from the internal non-volatile
memory, see
‘Storing and Loading Setup Files’
for more details.
Viewing Sequence Measurement Results
All sequence measurements are recorded in the buffer, see ‘
’ for more details.
By default, the CSV generated will contain the measurements for all the steps up to a maximum
of 100K steps. The file will contain the step (starting on 0) and the iteration, or repeat, starting
on 1.
If
Auto Store
is selected, a CSV file containing the measurements for a single step is generated
between steps.
NOTE
If Measurement control is set to
Constant Level,
Auto Store
will not generate separate CSV files
between steps .
Due to the nature of the sequence mode setups, each step can be set to measure different
measurement types.
For example, step 1 primary measurement = Voltage, step 2 primary measurement = Current.
The SMU records all Voltage, Current, Resistance & Power measurements in the buffer for each
step. The graph will use the primary measurement selected in ‘
to show
the results to avoid mixed data on the same axis.
NOTE
The total number of measurements recorded cannot exceed 100,000. The sequence will
continue to run when the measurement buffer is full, however no measurements will be
recorded.
