Staircase Sweep with Pulsed Bias
Measurement Mode
This mode forces swept voltage or current,
and measures DC voltage or current. A
second channel can be programmed to
output a pulsed bias voltage or current. A
third channel can be synchronized with the
primary sweep channel as an additional
voltage or current sweep source.
Sampling (Time Domain)
Measurement Mode
This mode displays the time sampled
voltage/current data (by SMU) versus
time.
Sampling channels: up to 6
For sampling intervals < 2 ms, the number
of sampling channels is 1
Sampling points: 1 to 10,001/
(number of channels)
Sampling mode: linear
Sampling interval range:
60 μs to 2 ms, 10 μs resolution
2 ms to 65.535 s, 1 ms resolution
Hold time: -30 ms to -100 μs, 100 μs
resolution
Bias hold time: 0 s
Bias Hold Function
This function is used to keep source output
after measurement. Source modules apply
the specified bias between measurements
in a quick test or application test that
defines some classic test setups, or a
repeat measurement. Also, the source
modules change the output value and the
unused modules are disconnected when
the next measurement is started.
Current Offset Cancel
This function subtracts the offset current
from the current measurement
raw data, and returns the result as the
measurement data. It is used to compen-
sate the error factor (offset current) caused
by the measurement
path such as the measurement cables,
manipulators, or probe card.
Other Measurement Characteristics
Measurement Control:
Single, Repeat, Append, and Stop
SMU Setting Capabilities:

Automatic Analysis Function
On a graphics plot, the markers and lines
can be automatically located using the
auto analysis setup. Parameters can be
automatically determined using automatic
analysis, user function, and read out
functions.

can be displayed on the graphics
screen.
Analysis Functions
Up to 20 user-defined analysis func-
tions can be defined using arithmetic
expressions.
Measured data, pre-defined variables
and read out functions can be used in
the computation, and the results can be
displayed on the LCD.
Read Out Functions
These built-in functions are for reading
various values related to the marker,
cursor, or line.
