The following
setmode
modifier
parameters are supported for SMU instruments.
modifier
value
Comment
KI_INTGPLC
<
value
>
(in units of line cycles)
Specifies the integration time the SMU will use for the
intg
X
and
sintg
X
commands. The default
devint
value is 1.0. The valid range is 0.01 to 10.0.
KI_AVGMODE
KI_MEASX
KI_INTEGRATE
Controls what kind of readings are taken for avgX calls.
The devint default value is
KI_MEASX
. When
KI_INTEGRATE
is specified, the integration time used is
that specified by the
KI_INTGPLC
setmode
call.
KI_DELAY_FACTOR
<
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.
KI_LIM_INDCTR
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_LIM_MODE
KI_INDICATOR
KI_VALUE
Controls whether the SMU returns an indicator value
when in limit or overrange, or the actual value measured.
The default mode after a
devint
is to return an indicator
value.
KI_OUTP_RELAY_STATE
KI_OUTP_HIZ
KI_OUTP_NORM
Only available if there are no preamplifiers.
KI_OUTP_HIZ
sets the state to high impedance (open).
KI_OUTP_NORM
sets the state to normal (closed, force V
0).
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.
