To Set Up Stress Source Channels - Agilent Technologies 4156b User Manual

To Set up Stress Source Channels

1. Press Stress key in the PAGE CONTROL key group.
2. Select CHANNEL DEF primary softkey.
3. In the MODE field of desired unit in CHANNELS area, select:
• V secondary softkey for dc voltage stress forcing mode (SMU, VSU, and
PGU).
• I secondary softkey for dc current stress forcing mode (SMU).
• VPULSE secondary softkey for ac voltage stress forcing mode (PGU).
• COMMON secondary softkey for circuit common (SMU and GNDU).
4. In the NAME field of desired unit in the CHANNELS area, enter the stress
channel name.
5. In the FCTN field of units that will be stress force channels, select SYNC
secondary softkey.
The stress channel name is only used for reference on the STRESS SETUP screen,
not on any results screen. So, you can omit the name if desired.
In the FCTN column, you can set up to four units to SYNC. At least one unit must
be set to SYNC in the FCTN column. The SYNC (stress force) units all start forcing
stress at the same time. The NSYNC (non-stress force units) channels start forcing
stress in sequence when state changes to stress force state. For this timing, see
"Stress Force Sequence" in Chapter 3.
If the row of a unit does not have settings, the unit is not used.
To disable a unit
In the row of the unit, select the DELETE ROW secondary softkey. The settings in
the row are deleted.
To set up non-stress output channels
Perform the following procedure.
1. Perform first 3 steps described above.
2. In the FCTN field, select NSYNC secondary softkey.
If you use two PGUs as pulsed sources (VPULSE), both must be SYNC or both
NSYNC.
