Math operation commands
Command Description
kfpabs (on page 13-51)
Takes a user-specified positive or negative value and converts it into a positive
value that is returned to a specified variable.
kfpadd (on page 13-51)
Adds two real numbers and stores the result in a specified variable.
kfpdiv (on page 13-52)
Divides two real numbers and stores the result in a specified variable.
kfpexp (on page 13-53)
Supplies the base of natural logarithms (e) raised to a specified power and stores
the result as a variable.
kfplog (on page 13-53)
Returns the natural logarithm of a real number to the specified variable.
kfpmul (on page 13-54)
Multiplies two real numbers and stores the result as a specified variable.
kfpneg (on page 13-55)
Changes the sign of a value and stores the result as a specified variable.
kfppwr (on page 13-56)
Raises a real number to a specified power and assigns the result to a specified
variable.
kfpsqrt (on page 13-57)
Performs a square root operation on a real number and returns the result to the
specified variable.
kfpsub (on page 13-58)
Subtracts two real numbers and stores their difference in a specified variable.
SMU commands
Command Description
adelay (on page 13-59)
Specifies an array of delay points to use with asweep
X
command calls.
asweepX (on page 13-
59)
Generates a waveform based on a user-defined forcing array (logarithmic sweep or
other custom forcing commands).
avgX (on page 13-62)
Makes a series of measurements and averages the results.
bmeasX (on page 13-63)
Makes a series of readings as quickly as possible. This measurement mode allows
for waveform capture and analysis (within the resolution of the measurement
instrument).
bsweepX (on page 13-
65)
Supplies a series of ascending or descending voltages or currents and shuts down
the source when a trigger condition is encountered.
devclr (on page 13-67)
Sets all sources to a zero state.
devint (on page 13-13)
Sets all sources to a zero state.
forceX (on page 13-69)
Programs a sourcing instrument to generate a voltage or current at a specific level.
getstatus (on page 13-
70)
Returns the operating state of a specified instrument.
intgX (on page 13-73)
Performs voltage or current measurements averaged over a user-defined period
(usually, one AC line cycle).
limitX (on page 13-75)
Allows the programmer to specify a current or voltage limit other than the default
limit of the instrument.
lorangeX (on page 13-
76)
Defines the bottom autorange limit.
measX (on page 13-78)
Allows the measurement of voltage, current, or time.
mpulse (on page 13-80)
Uses a source-measure unit (SMU) to force a voltage pulse and measure both the
voltage and current for exact device loading.
pulseX (on page 13-81)
Directs a SMU to force a voltage or current at a specific level for a predetermined
length of time.
rangeX (on page 13-83)
Selects a range and prevents the selected instrument from autoranging.
rtfary (on page 13-36)
Returns the array of force values used during the subsequent voltage or frequency
sweep.
