Screen Organization
STRESS Screen Group
• NAME of STRESS (optional)
Defines stress name that is used as a reference on STRESS: STRESS SETUP
screen. In this column, enter a desired name by using alphanumeric keys.
When pointer is in field of this column, DELETE ROW softkey is shown in
secondary softkey area: clears all the entries for a unit where the pointer is
located, and disables that unit.

• NAME must be 6 or less alphanumeric characters. First character must be

This field defines channels to be stress force channels or non-stress force
channels. In this field, select:
• SYNC secondary softkey to set channel to stress force channel.
• NSYNC secondary softkey to set channel to non-stress force channel.
The output timing is different for stress force channels and non-stress force
channels:
• Non-stress force channels output the source values in the order specified on
the MEASURE: OUTPUT SEQUENCE screen when state changes from
idle to stress.
• Stress force channels output the stress source values simultaneously when
the stress start trigger is received.
For details about output sequence, refer to “Stress Force Sequence” in Chapter
3.
Restrictions:
• At least one channel must be set to SYNC.
• Up to four channels can be set to SYNC.
• If both PGUs are set to pulsed source (VPULSE), you cannot set one PGU to
SYNC and other PGU to NSYNC. Both must be set to SYNC or both to
NSYNC.
