Instrument Control Panel
The Instrument Control Panel is selected using the icon ④. 1 or 2 SMUs can be
connected to the Control Panel. Each Instrument will populate one control box
⑤. For details on how to use the Instrument control box, see Instrument
control.
Entering Values
Values entered validate after 1s. This is to allow users to enter a decimal
point.
INSTRUMENT SETUP
Select an Instrument
Firstly, ensure Instrument Control is selected ①.
Select the drop-down box in the Instrument Control Panel ② to show all
instruments available.
If a connected instrument is not shown, see Connect.
The available instruments will be listed under the instrument name e.g.
‘SMU4001’ for the SMU4001 source measure unit. If there is a mode or a
sequence in the editor, you will be asked if you want to keep it or load the
current mode/sequence from the instrument.
Select the instrument ③ to activate the Instrument Control Panel.
The instrument name will now be shown ④, in addition following additional
information will be shown:
- COM port details or IP address
- Serial number
- Sequence mode status
- Active mode
- Active shape
- Buffer status (the status will show green unless it is > 90% full when it will turn red)
A coloured strip will be allocated ⑥ on the left, indicating the product
category.
The instrument can be given a unique name, using the edit box ⑦.
The meter digits show live readings when they are available (if off
measurements are turned off, they will not be shown).
NOTE
The channel output state will match the instrument when connected, this may be
on or off depending on the setup.
To disconnect an instrument, select the connected instrument from the drop-
down box. This will reset the Instrument Control Panel back to the default
state. If an instrument is connected and communication is lost, a ‘Comms
Error’ will show ⑧. Check connections and reconnect as shown above. The mode
or sequence in the editor will stay. This allows you to edit a mode or
sequence off-line before reconnection (or connecting to another instrument)
and applying it.
Instrument control
To run the setup, use the Run and Stop ① buttons.
If the instrument is in a mode that uses the source, the source level and
limit are shown in ②.
The live primary and secondary results are shown in ③ unless the output is
off, and off measurements are disabled.
Instrument menu
To access the Instrument Menu, select the Menu button ④. This menu contains
settings and functions such as O V P, limits, ranges etc. These are instrument
specific and will vary depending on the instrument connected.
Each block of settings is contained within a tree view ⑤, the selected setting
on the left ⑥ defines the available parameters ⑦ on the right. If no parameter
is available, the action has no numeric value option.
NOTE
By default, only the commands for the active mode are visible, to access the
commands for all the other modes un-tick ⑧. If the command to change the mode
is sent and the “Filter by active mode” is ticked the tree will refresh to
show the commands for the new mode.
Selecting a command will display the description and an example (referenced
from the Programming Manual). Commands that have string parameters with fixed
options, will be shown in a dropdown list. Commands with numeric parameters
will allow the user to enter a value in a text box.
Commands where the numeric parameter has units will also have a dropdown list
of the allowed units. Units are optional, where they are omitted, the base
units will be used e.g. V, A, W, Ω or s.
Press Send ⑨ to send the formatted set command ⑩. Alternatively, right-click
to execute the example.
Press Query ⑪ to send the formatted query command ⑫. The response will be
shown in the “Response” box.
NOTE
All commands are in the tree for reference. However, some cannot be executed,
these commands would be used to either to send / receive files to / from the
SMU or would return large amounts of binary or ASCII data.
SETTINGS
The settings tab provides an interactive display of the settings for an SMU,
it also allows setups to be created without an SMU connected.
The following options are available:
Model: Select the model that the setup will be created for e.g. SMU4001. This
is only available when an instrument is not connected.
NOTE
Setups are model specific, e.g. A setup created for an SMU4001 will not run on
an SMU4201. However, Setups and Sequences can be converted from one model to
another using Test Bridge whilst the instrument is not connected.
Mode: Select the mode of the setup. This can be any of the following: SV
Mode, SC Mode, LC Mode, LR Mode, LP Mode, MV Mode, MC Mode, MR Mode, MHR Mode
or Sequence.
Selecting a mode will show the editor for the mode.
Easy Setup: Open the Easy Setup window, see Easy Setup Window for more
details.
Open File: Load a setup (.stp) or sequence (.seq) from a file into the
editor.
Save As: Save the setup or a sequence to a file.
NOTE
Save As and Apply will not be available if the setup or sequence have errors.
When a setup or sequence that contains list is saved, a folder containing the
file with the same name as the setup or sequence (for the list .CSV files)
will also be saved to the chosen location.
Expand All: Show (expand) or hide all hidden sections of a setup or
sequence in the editor The following options are available once an instrument
is connected, data has been collected or parameters have been changed:
Read: Manually read the buffer for the connected SMU, only if it contains
data.
Cancel: Cancel all changes and reload the active setup or sequence from
the instrument.
NOTE
If the setup or sequence contains a list and is then cancelled, lists will not
be loaded.
Apply: Send the setup or sequence to the instrument.
Easy Setup Window
The Easy Setup menu contains a number of pre-configured setups, providing
instant configuration for basic operational use of the SMU. Select the setup
from the dropdown list ①.
A brief description of the selected mode and mode specific options will become
available ②, if no options are available only the description will appear.
Enter the required values and select OK ③ to activate the mode with the set
options, selecting Cancel ④ will close the window and no changes will be
applied.
Mode Editor (Manual Setup)
The Mode Editor contains options for the source and measurement operating
functionality. Once a mode has been selected, mode specific options will
become available. For sequence mode See Sequence Mode Editor.
The Mode Editor is grouped into sections (as appear on the SMU GUI – Manual
Setup):
Overall: General settings for the selected mode.
Source/Sink/Measure: The shape, control, limits and protection.

③.
NOTE
Changes will be shown in the Mode Editor. To apply the latest changes to the
SMU, press the Apply button in the Settings section.
List Source Shape
The list source shape editor has the following additional
options:
Import: Import a list of levels from a CSV file. If the CSV file contains
multiple columns, a pop-up will appear with the option to select the column to
import.
Export: Export the present list of levels to a CSV file.
Build: Open the Arb generator, this allows a custom list to be created,
see Arb Generator.
Clear: Remove all points from the list.
Sequence Mode Editor
The Sequence Mode Editor allows for the setup and configuration of multiple
steps to form a sequence. This is created using user stored configuration
setups that are loaded into the sequence model to create a base for the
additional actions. The Sequence Mode Editor has the following options:
DIO Config: Open the DIO Config window, used to configure
the DIO pins.
Add: Add a new step to the end of the sequence, up to a maximum of 25.
Duplicate: Duplicates the selected step, adds the step to the end of the
sequence.
Insert: Insert a new step before the selected step.
Delete: Delete the selected step
Step Order: Drag and drop the steps in the list box to re-order them.
To start building a sequence, Add a step. The steps are shown in order going
across the window from left to right. See Sequence Step Editor for details of
how to edit a step.
Sequence Step Editor
The sequence step editor allows the following:
- Build/load a setup
- Set delays
- Repeat and jump to and from steps
- Create multiple triggered events
- Set output statuses
The Sequence Step Editor provides the options to edit the step of a sequence.
Each step must have a setup added, a default setup has been added to get
started. only one configuration setup can be added to each step.
The top of the sequence shows an overview of the step and what order things
will happen. Selecting an item in the overview will show more settings for
that item below.
See the SMU4000 Series Instruction Manual details on what can be set, this can
be found at: www.aimtti.co.uk/support
Selecting the mode box ① will show the mode editor ②. It is
possible to set the name of the mode and thestep.
Easy Setup: Open the Easy Setup window, see Easy Setup Window for more
details.
Load: Load a setup (.stp) from a file into the editor.
Save As: Save the setup to a file.
Arb Generator
The Arb generator provides the tools to create a custom list of points that
can be loaded as a list into a setup. A range of built-in step options are
available, including: sine wave, square wave, triangle wave, ramp, and step.
To add a step to the arb, select a shape from the options in the step
selection ①.
Each shape has a unique pop-up window that gives the editable parameters for
that shape:
Each step has the option to Insert, Add or Cancel:
Insert- Place the step BEFORE the selected step.
Add- Place the step AFTER the last step.
Cancel- Return to the sequence without making any changes.
There is also an option to name the step.
Steps are listed on the left-hand side ②, these can be selected and the
following actions can be applied using the tools ③:
Edit: Edit the selected step. Opens the edit window.
Duplicate: Duplicates the selected step and opens the edit window.
Delete: Delete the selected step.
Save: Save an arb as a .CSV or .ARB file.
NOTE
Arb files allow you to edit the arb steps later. Saving as a CSV file will not
allow you to edit the arb, you will only be able to load the points into a
list.
Load: Load an .ARB file.
If the Arb Generator was opened from the list editor clicking OK will return
the arb as a list of points to the list editor. You will be asked if you want
to replace the current list or append the new points to the current list.
RESULTS
The results section is split into 3 tabs: Data, Table and Graph
Data
The Data tab shows the values in a dataset that have been loaded from the
instrument or a file, these are loaded from the Loaded Datasets ① panel, click
to select the required dataset or right click to rename or remove it.
Table/Graph
The data shown in the table tab shows the data selected in the
Datasets section ② of the graph configuration panel, this is the data used to
configure the graph.
Graph Configuration
There are two types of graph: One Dataset and Two Datasets, each with their
own settings.
One Dataset
Allows the plotting of data from multiple datasets. Choose the X and Y
parameters, axis type (linear or log) and any grouping ③. For each dataset
tick to show on the primary and/or secondary y axis ④.
Grouping is for use with results from a sequence ⑤. Grouping can be done on
change of step or change of repeat. Split will insert a break in the data but
leave the data in the same series. New Series will create a new series for
each group.
Graph Features- One Dataset
Datasets, Parameters and Graph Types
To show data on the graph, select the tick box of the required dataset ①. A
graphical representation of the selected data will be shown, based on the
graphs default settings.
The X ②, Y1 ③ & Y2 ④ graph axes types can
be changed using the Parameter settings ⑤.
To show alternative parameter types from the loaded data, select an option
from the drop-down box. The options are Voltage, Current , Power or
Resistance, the X axis also include the options of Elapsed Time and Absolute
Time.
Each graph axis type can be displayed in
either a Linear or Log (logarithmic) format using the Type settings ⑥.
There are two Y Axis options:
Y Axis-1 (Right)
Y Axis-2 (Left)
When both are selected for a single dataset ⑦ the data will be shown on one
graph. Each variation of data shown is assigned a colour ⑧.
Grouping
Grouping is designed to be used with measurement data collected from the SMU
when in Sequence Mode, the recorded measurement data must contain steps and/or
repeats for grouping to work.
Grouping allows you to split a dataset when a step repeats or changes. Steps
and/or repeat grouping can be viewed as None, Split or New Series.
NOTE
If X axis is set to Elapsed time, the time will reset at the start of each
series. See example ③ (below).
Step grouping must be set before repeat grouping settings are availiable.
Grouping by Step- These examples show a sequence with 3 steps and no
repeats:
- None – Entire dataset is shown as a continous line of data.
- Split – Each step within the dataset is split into individual steps on the X Axis.
- New Series – Each step within the dataset is shown as a new series on the X Axis.
Grouping by Repeat- These examples show a sequence with 3 steps and 4 repeats:
- None – Entire dataset is shown as a continous line of data.
- Split/Split- Each step and repeat within the dataset is split into individual steps and repeats on the X Axis.
- New Series/Split- Each step within the dataset is shown as a new series on the X Axis. Each repeat within the dataset is split within the series.
- New Series/New Series- Each step and repeatwithin the dataset is shown as a new series on the X Axis.
Two Datasets
This graph allows you to plot data from one dataset against data from a
second. To allow the application to match the data you need to select the
parameter on which the datasets should be joined and any tolerance in the
joining ①.
NOTE
Take care when joining datasets together that contain multiple steps or
repeats, such that parameters with the same value are matched correctly. E.g.
data from a sequence with multiple steps and / or repeats with similar data
may not join as expected.
When joining two datasets you need to select which parameters should be used,
they can be any of the following: Index, Absolute Time, Relative Time, Voltage
(V), Current (A), Power (W) or Resistance (Ohms). A tolerance can also be set
, this is the range of values that can be matched between the two datasets.
For example, if you were measuring currents on two SMUs where the set voltage
is being swept in the same sweep and you want to compare the values, the
voltages being measured would be very similar but not exactly the same,
setting the tolerance to half the step size would allow the two datasets to be
connected and allow you to plot current 1 against current 2. Once the datasets
are joined you can plot and group parameters in the same way as you can in the
“One Dataset” graph with one addition, when grouping the y axis dataset is
used unless you tick the “Use X Axis” tick box ②.
Graph View
The View menu can be used to show or hide graph 1 or 2, if one graph is hidden
the remaining one will fill the graph display area. If both graphs are
visible, the size can be adjusted using the central splitter bar.
Show Values – Click and drag the mouse across the graph ①
to show the details ② of that specific point in the logged data. This can be
dragged along the entire data line to show any point within the log.
