SEQ Edit1.1 General

1.1 General
The Sequence Edit Software is a program that supports a sequence function of theWF1973/WF1974 MULTIFUNCTION GENERATOR.
This software runs under the Windows 2000 and XP operating systems in a personal computer(PC), and controls transfer of control data, and sequence data on the WF1973/WF1974
MULTIFUNCTION GENERATOR via a USB interface and execution of other operations.
The following are the main functions of this software:• Creating, editing, and saving sequence data
• Transferring sequence data to the WF1973/WF1974• Reading sequence data to the WF1973/WF1974• Transferring arbitrary waveform data to the WF1973/WF1974• Previewing sequence data
• Controlling the sequence run to the WF1973/WF1974• Displaying the progress of the currently running sequence on the monitor
For operation details of the sequence function, see the WF1973/WF1974 Application Instruction
Manual.

1.2 On-line/Off-line
The Sequence Edit Software checks for connected devices at startup.
If a connected device is detected, the software starts in the “on-line” status where devices can becontrolled.
If the specified device is not connected, the software starts in the “off-line” status and does notcommunicate with any device. It is possible to create a device setting file or edit
sequence data even in the “off-line” status.

1.3 Conventions
The following conventions are used in this manual.
• Menu names displayed on the screen, user input strings, and other elements: block letters
enclosed by square brackets ([, ]).
Examples: [Waveform(T)], [s=2*pi;]• Button names displayed on the screen, user’s key operations, and other elements: block
letters enclosed by a box ( ).
Examples: Cancel , OK , Alt• Press one key while holding down another key: Two keys are connected by a plus (+)
symbol. Example: Ctrl + O• Press one key, release it and press another key: Two keys are divided by a comma (,).
Example: Alt , F

3.3 Start and Termination
For how to start the SEQ Edit, click [SEQ_EDIT] in Start − [Program] − [NFTool] −[SEQ_EDIT].
The message in “ Figure 3-1” appears when the software is started for the first time or when thepreviously set device is not connected.
If not a single unit is connected at startup, the software is started in the off-line state.
If a unit is connected, the software starts in the on-line state. However, if several units of the samemodel are connected, the message shown in “ Figure 3-1” is displayed.

Figure 3-1 Message Displayed When Sequence Edit Software Is Started
When OK is clicked, the software is started in the off-line mode. The system setting screen isdisplayed. On the system setting screen, set the serial number of the unit to be set.
“ 5.7 System Settings”
When using the WF1974, the software starts in the on-line state only when it is started for the firsttime. On the system setting screen, change the model setting. During the second and subsequent
startups, an equipment connection check for the model that was used the previous time (WF1973 or
WF1974) is performed.

The software is exited when [File(F)] - [Exit(X)] ( ALT , F , X ) is selected or the Close button
is clicked. At this time, the data that was being edited is saved and is reflected at the next startup.

Setting parameters

You can set each parameter by inputting the desired value directly into the selected cell. The input
values are checked for range appropriateness.
The channel parameter setting area may contain parameters that do not require setting depending on
the type of waveform. "----" is displayed for such parameters and no value can be input.
Selecting [Edit(E)] - [Initialize(A)] can return the selected set values to the defaults.
The items that cannot be selected through direct input are described below.

a) Setup from Combo Boxes
To set a value in [AutoHold], [StepTerm], [StepCode], [Waveform], [Amplitude
Range], or [DutyExtend], click the desired cell and select the value from the combo box asshown in “ Figure 3-3”.

Figure 3-3 Combo Boxesb) Numerical input with on/off setting
To set a value in [StopPhs], [EventBranch], [StateBranch], [JumpTo], or [JumpCnt],
after parameter set on/off from the radio button.
An end phase input example is described below.
Clicking the [StopPhs] cell displays the radio buttons with On (Valid)/Off (Invalid), as shownin “ Figure 3-4”. The stop phase can be enabled or disabled by switching the radio button setting.
If Off is selected, the corresponding cell will gray out and it will not accept any entry. If On isselected, the cell will display the default value.

SEQ Edit3.4 Sequence Edit Area

Clicking here displays the radio buttons withwhich the step stop phase can be enabled or
disabled.

In the case of jump count ([JumpCnt]) only, the setting is that of [Infinity/On] and not the[On/Off] setting. Moreover, when the jump destination ([JumpTo]) setting is Off, the jumpcount setting cannot be done.

c) Operation type setting
In the case of the frequency, amplitude, offset, start phase, and duty, in addition to a value
setting, there is also an operation type setting ([Const], [Keep], [Sweep]).
Clicking a cell in these parameters setting area displays the radio buttons with which theoperational types can be set. The operational type can be enabled or disabled by switching theradio button setting.
Channel parameter setup cells, except some, in this area are color-coded according to theoperational type. The cell color representing each operational type corresponds to one of the
background colors of the radio buttons with which this type can be set.

3.4.3

Copying the sequence data

The sequence data can be copied in either the step control parameters or channel parameters
setting area.
Follow the procedure below to copy the sequence data.
<1> Select the sequence data to be copied, including the operational type setting.
<2> Select [Edit (E)] – [Copy (C)] ( ALT , E , C ) to copy the data.
<3> Select the destination.
<4> Select [Edit (E)] – [Paste (P)] ( ALT , E , P ) to paste the data.
Although data can be selected in cell, line, and same row units, if the format of the selected data
differs from that of the copy destination, paste is not possible. That is, data in one cell orcolumn cannot be copied to a cell or column in another column.
