Measurement
The 4155C and 4156C can
perform dc or pulsed force/measure,
and stress force. For dc,
voltage/current sweep and sampling
(time domain) measurements are
available.
Voltage/Current Sweep Measurement Characteristics
Each SMU and VSU can sweep using
VAR1 (primary sweep), VAR2
(subordinate sweep), or VAR1|
(synchronous sweep).
VAR1
Primary sweep controls the staircase (dc
or pulsed) voltage or current sweep.
Maximum number of steps: 1001 for one
VAR1 sweep.
Sweep type: linear or logarithmic
Sweep direction: Single or double sweep
Hold time:
Initial wait time or wait time after
VAR2 is set: 0 to 655.35s with 10ms
resolution
Delay time:
Wait time from VAR1 step to the start
of the measurement: 0 to 65.535s with
100 µs resolution
VAR2
Subordinate linear staircase or linear
pulsed sweep. After primary sweep is
completed, the VAR2 unit output is
incremented.
Maximum number of steps: 128

VAR1
Staircase or pulse sweep synchronized
with the VAR1 sweep. Sweep is made
with a user specified ratio and offset
value. VAR1
VAR1
user specified ratio and “b” is the user
specified offset value.

output is calculated as
|
= a × VAR1 + b, where “a” is the
CONSTANT
A source unit can be set as a constant
voltage or current source depending on
the unit.
PULSE
One of the SMUs can be set as a pulse
source.
Pulse width: 0.5ms to 100ms, 100µs
resolution.
Pulse period:
(5ms to 1s (≥ pulse width + 4ms),
100µs resolution.
SMU pulse setting accuracy
(supplemental information, at fixed range
measurement except multi- channel
measurement):
Width: 0.5% + 50µs
Period: 0.5% + 100µs
Trigger output delay for pulsed
measurement: 0 - 32.7ms with 100µs
resolution (< pulse width).
Sampling (Time Domain) Measurement Characteristics
Displays the time sampled voltage/
current data versus time.
Maximum sampling points: 10,001
(linear)
Sampling mode: linear, log, and
thinned-out
Note: The thinned-out mode is similar to
reverse-log sampling. Sampling
measurement continues by thinning out
older data until the sampling completion
condition is satisfied.
Sampling interval range and resolution:
Linear scale (auto mode):
60µs to 480µs range: 20µs resolution
480µs to 1s range: 80µs resolution
1s to 65.535s range: 2ms resolution
Linear scale (no limit mode), log
scale, and thinned-out modes:
560µs (720µs at thinned-out mode)

be defined.

480µs)
0.5% + 10µs (480µs ≤ sampling

0.5% + 100µs (2ms ≤ sampling
interval)
C-V Measurement Characteristics
Capacitance is calculated value
derived from the following
equation:
dQ
C =
dQ is the charge when dV, the step
voltage, is applied by the SMU;
dQ is derived from the measurement current (amps) and the
integration time (seconds).
Measurement Range:
Measurement range depends on the
current range, integration time, and
step voltage (refer to the chart in
supplemental data).
Capacitance Calculation Accuracy:
Accuracy is dependent on accuracy of the
current measurement and voltage measurement, and the stray capacitance and
leakage current of measurement system etc
(Refer to the chart in supplemental data).
Zero Offset:
Cancels stray capacitance of the fixtures
and test leads.
Leakage Current Compensation:
Cancels the influence of the leakage current to the capacitance measurement.
dV
Stress Force Characteristics
SMU, VSU, and PGU output can be
forced for the user specified period.
Stress time set range:
5000µs to 31,536,000s (365 days)
Resolution:
100µs (500µs≤stress time≤10s)
10ms (10s<stress time≤31,536,000s)
Burst pulse count:
1 - 65,535 (PGU only)
Trigger:
The 4155C and 4156C output a gate
trigger while stress channels are
forcing stress.

Knob Sweep
In the knob sweep mode, sweep range
is controlled instantaneously with the
front-panel rotary knob.
Only the Channel Definition page needs
to be defined.
Standby Mode

programmed to their specified output
value even as other units are reset for
the next measurement.
Other Characteristics
Limited auto-ranging, voltage/current
compliance, power compliance,
automatic sweep abort functions,
self-test, and self-calibration.

The 16440A switches either an SMU

You can expand to 4 channels by adding
an additional 16440A. The channel 1
PGU port provides “PGU OPEN”

by opening a semiconductor relay. The

they cannot be measured.
There is a possibility that the
