A and stores them in a buffer.

Details
The
smu
X
.measure
Y
andstep()
function makes a measurement and then sets the source to
sourceValue
. Usage of the
smu
X
.measureivandstep()
function is similar, but makes two
measurements simultaneously; one for current (
i
) and one for voltage (
v
).
Measurements are in the following units of measure:
v
= volts,
i
= amperes,
r
= ohms,
p
= watts.
The specified source value should be appropriate for the selected source function. For example, if the
source voltage function is selected, then
sourceValue
is expected to be a new voltage level.
Both source and measure autorange must be disabled before using this function. This function cannot
be used if source high capacitance mode is enabled (high capacitance mode requires autoranging to
be enabled).
This function is provided for very fast execution of source-measure loops. The measurement is made
before the source is stepped. Before using this function, and before any loop this function may be
used in, set the source value to its initial level.
