Model 4200A-SCS Parameter Analyzer Reference Manual
The following setmode modifier parameters are supported for SMU instruments.
modifier
KI_INTGPLC
KI_AVGMODE
KI_DELAY_FACTOR
KI_LIM_INDCTR
KI_LIM_MODE
KI_OUTP_RELAY_STATE
The following SMU modifier parameters are accepted, but do no operations in the 4200A-SCS.
They are included for compatibility so that existing S530 or S600 programs that use setmode can be
ported to the 4200A-SCS without generating errors.

Comment
Specifies the integration time the SMU will use for the
<value>
intgX and sintgX commands. The default devint
(in units of line cycles)
value is 1.0. The valid range is 0.01 to 10.0.
KI_MEASX Controls what kind of readings are taken for avgX calls.
The devint default value is KI_MEASX. When
KI_INTEGRATE
KI_INTEGRATE is specified, the integration time used is
that specified by the KI_INTGPLC setmode call.
<value> This factor scales the internal delay times used by the
SMU. A value larger than one increases the delays; a
value less than one decreases the delays. A minimum
delay is enforced by the SMU.
This command should not be used when setting the
SMU speed to FAST, NORMAL, or QUIET modes; the
delay factor is set internally by these modes, so
changing the value while using one of the predefined
modes corrupts the speed settings or the delay factor.
Any
Controls the measure value that is returned if the SMU is
at its programmed limit. The devint default is
SOURCE_LIMIT (7.0e22).
NOTE: The SMU always returns INST_OVERRANGE
(1.0e22) if it is on a fixed range that is too low for the
signal being measured.
KI_INDICATOR Controls whether the SMU returns an indicator value
when in limit or overrange, or the actual value measured.
KI_VALUE
The default mode after a devint is to return an indicator
value.
KI_OUTP_HIZ Only available if there are no preamplifiers.
KI_OUTP_NORM KI_OUTP_HIZ sets the state to high impedance (open).
KI_OUTP_NORM sets the state to normal (closed, force V
0).
