Making a Measurement
Stress Force
To Set up Stress Condition/Timing
1. Press Stress key in the PAGE CONTROL key group.
2. Select STRESS SETUP primary softkey.
3. In the MODE field of the STRESS MODE area, select:
• DURATION secondary softkey to specify how long to force stress.
• PULSE COUNT secondary softkey to specify how many pulses to output for
force stress (for ac stress only).
4. In the DURATION or PULSE COUNT field, enter the duration or pulse count.
You can select FREE RUN secondary softkey to output stress continuously.
5. In the
STRESS Status
field, select:
• CONT AT ANY secondary softkey to continue forcing the stress even if an
abnormal status occurs.
• STOP AT ANY ABNORM secondary softkey to stop forcing the stress
when any abnormal status occurs.
• STOP AT COMPLIANCE secondary softkey to stop forcing the stress only
when SMU reaches its compliance setting.
STOP AT ANY ABNORM and STOP AT COMPLIANCE secondary softkeys
are displayed only when specified duration is more than 10 s. If you set pulse
count mode, these secondary softkeys are displayed only when
pulse period
´
pulse count is more than 10 s.
Stress stop function is not effective until stress has been forced for 10 s.
In the duration mode, you set time (in seconds) for stress forcing. In the pulse count
mode, you set an integer to specify how many pulses to output for stress forcing.
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.
