CHANNELS Screen Group
• If both PGUs are set to VPULSE, the STBY settings of both PGUs must be
same.
FCTN.
This field defines an output function for SMUs, VSUs, PGUs, and GNDU. When
the pointer is located in this column, allowable output functions appear in the
secondary softkey area. You select a softkey to set an output function.
• SMU or VSU: you can set VAR1, VAR1', VAR2, or CONST.
• PGU or GNDU: you can set CONST.
Restrictions:
• In FCTN column, you cannot set multiple VAR1, VAR1', or VAR2. For
example, you cannot set VAR1 for 2 units.
• If VAR1' is set, you must set VAR1 also.
• If VAR2 is set, you must set VAR1 also.
• The output modes of VAR1 and VAR1' must be same. That is, the MODE setting
for both must be set to a voltage mode, or both must be set to a current mode.
For example, you can set VAR1 to V and VAR1' to VPULSE.
• You cannot set VAR1, VAR1', or VAR2 for sampling measurement. You can set
CONST only.
STBY.
STBY field specifies which channels output source values in the standby state.
• If STBY is set to ON, the unit forces a specified output value when in the
standby state.
• If STBY is blank, the unit outputs 0 V in the standby state (same as when in idle
state).
See “Types of Operation State” in Chapter 3 for more information on the standby
state.
Restrictions:
• If both PGUs are set to VPULSE, the STBY setting of both PGUs must be the
same.
• For STBY=ON channel, SERIES RESISTANCE setting must be 0 ohm.
