Screen Organization
STRESS Screen Group
ACCUMULATED STRESS
The ACCUMULATED STRESS field on this screen and on STRESS: STRESS
FORCE screen are linked. So, if value is changed on this screen, value is changed to
same value on STRESS: STRESS FORCE screen and vice versa.
To change the displayed accumulated stress time, enter the time in this field.
Selecting RESET ACCUM STRESS secondary softkey resets the displayed
accumulated stress time to 0 (zero).
HOLD TIME
In the HOLD TIME, you can set the hold time. After the stress force state starts, the
stress force channels wait the specified hold time, then start forcing stress at the
same time.
For details about hold time, see example figure in “Stress Force Sequence” in
Chapter 3.
FILTER
FILTER field specifies SMU filter to
ON
or
OFF
. If this field is set to
ON
, overshoot
decreases, but settling time takes several ms. If you set dc stress to short stress force
time, set
OFF
in this field if you want the stress signal to be more pulse shaped.
STRESS Status
• Select CONT AT ANY secondary softkey (stress will continue even if an
abnormal status occurs). Abnormal status means the following:
• SMU reaches its compliance setting.
• Current of VSU exceeds ±100 mA.
• SMU or VSU oscillates.
• A/D converter overflow occurs.
• Average current of PGU exceeds ±100 mA.
• Select STOP AT ANY ABNORM secondary softkey (stress will stop if any
abnormal status occurs).
• Select STOP AT COMPLIANCE secondary softkey (stress will stop only if
SMU reaches its compliance setting).
