Figure 2-10
Instrument information, forcing functions, and voltage sweep function parameters
1
Do not change these parameters, unless you want to customize the ITM — which is beyond the scope of this User’s manual.
2
Dual sweep – with dual sweep enabled, the SMU will sweep from start to stop, and then sweep from stop back to start. When disabled, the SMU will sweep
from start to stop. For details, see Understanding dual sweep on page 2-15.
Figure 2-11
Linear sweep or step, SMU range, Pulse Mode, and SMU current compliance
3
In a list sweep configuration window, you enter a list of discrete voltages or currents, instead of start, stop, and step values. In a current bias or voltage bias
configuration window, you enter a fixed level value, instead of start, stop, and step values.
4
Pulse mode – Select Pulse Mode to provide pulse output for sweep (linear, log and list) and bias forcing functions. For details, see Understanding pulse mode
on page 2-16.
Describes the instrument selected for
this device terminal and the mode of the
test being performed. (Sweeping mode
or Sampling mode — in which data is
recorded vs. time for an applied signal).
Select whether a sweep or
step forcing function acts as
a master (independent) or
slave (tracks the master).
1
Select the present forcing
function.
1
Select Dual Sweep.
2
Select whether a sweep is
linear or logarithmic.
1
For a Linear sweep or step Start is the voltage / current at the start
of the sweep, Stop is the voltage / current at the end of the sweep,
and Step is the voltage / current change between steps.
3
Data
Points — calculated automatically from the Start, Stop, and Step
values — is disabled. For a Log sweep, you specify the Data Points
value. The Step value — calculated automatically — is disabled.
Select the SMU
range to be used
when forcing the
specified voltage
or current. Select
dynamically opti-
mized range
(Auto), single best
range for entire
sweep (Best
Fixed), or manually
specified numeri-
cal range.
Select and configure
Pulse Mode.
4
Select the SMU current compliance for a
voltage sweep or the voltage compliance
for a current sweep.
