Software Startup & Sample Acquisition

The program installation CD-ROM contains both a 16-bit and a 32-bit version of WaveView. The figures in
this document module reflect the 32-bit version, only. Note that the 16-bit version has fewer toolbar
buttons and exhibits minor screen differences.

Startup WaveView

Start WaveView by double-clicking on its icon. WaveView holds user-configured parameters that can be
saved to disk. The default configuration filename is
the working directory for this configuration file. One of the following situations will occur:

•

If the default configuration file is f ound, all the required setup information is extracted from it, and

the application’s main window opens.

•

If the default configuration file is not found, WaveView attempts to connect with WaveBook using

the following default parameters: Printer Port LPT1, Interrupt Level 7, and 4-bit Standard Protocol. If
this fails, the program tries LPT2 and Interrupt Level 5.

•

If connection is established, WaveView’s main window opens.

Note: If connection to the device can not be

established, a WaveView StartUp box
appears with the following options:
Retry, Select Device, Load File, and Exit.

WAVEVIEW.CFG

. When WaveView starts up, it searches

WaveView StartUp Box

WaveView

03-05-02

WaveView, pg. 3

Reference Note:
Refer to the WaveBook User Manual’s Troubleshooting chapter for advice regarding connection
problems.

•

If no user-configuration file is found , or if no communication established, a dialog box prompts you

to choose an actual WaveBook from the device inventory, or to select a simulated device.

Select Device Box

Simulated WaveBook. If the hardware is not available, or if yo u j ust want to practice using the software,

select Simulated Device. The Simulated Device allows you to run vario us software functions with no
hardware concerns.

The Simulated mode is also available from WaveView’s pull-down menu. To select the simulated mode:

1. Choose Select Device from the System pull-down menu.

2. Select Simulated Device from the Available Devices list.

WaveBook Attached. If the WaveBook hardware is connected and switched on, select the applicable
WaveBook device. Then click on the Properties button to view the Device Properties screen (see following
figure).

Devices Properties (example)

After you have selected the device parameters, click Close.
WaveView attempts to find the WaveBook at the specified port. One of the following situations will occur:

•

The hardware is found, the WaveView main window opens.

•

The hardware is not found, a dialog box informs you and provides another chance to select

parameters.

WaveView, pg. 4

03-05-02

WaveView

WaveView interrogates the hardware after it starts up to see what options and expansion modules are
actually connect ed to the WaveBook. The number of channels (shown on the co nfiguration menu)
represents the number of channels actually connected to WaveBook.

Configure Channels

Once WaveView determines the options and expansion modules, the individual channels can be configured,
as described in the text that follows.

If WaveView cannot identify the hardware, and you have verified that the selected hardware
parameters are correct, exit WaveView and then use the “Test Hardware” feature of the
Daq* Configuration control panel. A discussion of System Testing is included in the

System Setup and Power Options chapters of WaveBook Manuals 481-0901 and 489-0901.

Configuring Channels from Wa veView’ s Main Window (Partial View)

•

On/Off - To acquire data with WaveView, channels must be properly connected to signal sources, and
must be enabled (On). Channels can be enabled as follows:

(1) Click in a channel’s On/Off cell, then select "On" from the drop-down menu (that appears

above the range column), or

(2) Double-click in a channel’s On/Off cell to toggle to “On.” Note that the on/off status will

change with each double-click, or

(3) Click on the toolbar’s “On” button (Make All Channels Active) to turn all channels on. Note

that the “Off” button (Make All Channels Inactive) turns all channels off.

•

Label - Channels have default labels, such as CH05. You can change the label by clicking on the cell,
then typing in the new label. Labels must be unique, i.e., each channel must have its own label.
Attempts to use duplicate labels, or use no label will result in a warning message.

•

Readings - Not user configurable. This column displays values of enabled channels.

•

Units - Select a channel’s units in one of two ways.

(1) Click in a channel’s Units cell, then select the desired units from the p ull-down menu.
(2) Double-click in a channel’s Units cell to cycle through the units. Note that when the mX+b

dialog box appears you need to click “OK” to continue cycling.

Note: You can enter user-defined units from the mX+b dialog box, and you can use the mX+b

equation to adjust a channel’s scale and offset. Refer to Units on page 14 for more information
and an example of the mX + b equation being used.

•

Range - Select a channel’s range in one of two ways.

(1) Click in a channel’s Range cell, then select the desired range from the drop-down menu.
(2) Continue to double-click in the applicable channel’s Range cell to cycle through the available

ranges. Stop double-clicking when the desired range is indicated.

Collect and View Data

The following text describes how to collect data for a sample acquisition, and how to view a graphic
representation of the data.

To read and view a graphic representation of WaveBook data, select the Scope option from the View menu
or use the toolbar button. This accesses the WaveView Scope window. Complete the acquisition setup as
follows:

•

Number of Charts. First, the Scope window should be configured to display 4 charts since 4 channels

were previously selected for the acquisition. Select the Number of Charts option from the Charts menu

item. When the flyout appears showing a selection of up to 8 channels for display, click on 4.

•

Arm and Trigger. The system is now set to start collecting data. At this point, you ma y acquire one

acquisition or continuous acquisitions. For this sample acquisition, click the Arm button, then click the

Trigger button.

•

Data Acquisition. The system has now collected 1000 pre-trigger scans and 5000 post-trigger scans.

•

View additional channels (up to 8) simultaneously by changing the entry in the Number of Charts

menu.

•

Change the channels viewed. Use the channel select list box at the right of the waveforms to display

waveforms of other active channels.

•

To scale the waveforms, click on the Scale All Charts button. All 4 waveforms should then be visible.

•

Examine the waveforms at any point along the timeline by using the horizontal scroll-bar.

•

Vary the number of scans displayed by using the Zoom In or Zoom Out buttons.

WaveView, A Detailed Reference

When WaveView starts it interrogates the system hardware to see what options and expansion modules are
actually connected to the WaveBook. Unless you are using WaveView’s simulated mode, the channels
displayed on the WaveView.cfg window correspond to actual connected channels.

WaveView functions are initiated through toolbar buttons and pull-down menu selections. The toolbar

buttons were identified on page 2. An explanation of menu functions, in order of the menu structure, begins

in the "Pull-down Menu Commands" section, below.

WBK17 Note -

If the On/Off column selection indicates multiple 16-bit values, WaveView will make an automatic
selection of which value to display in the Readings column. This automatic selection will be according to
the following rule: the CtrLo value is preferred over the Volts value, and the CtrHi value is preferred over
the CtrLo value.

Unlike the Readings Column, acquisition data will include all selected WBK17 16-bit data channels.
For example, if “Volts and CtrLo and CtrHi” were selected as the “On/Off” value for all 8 channels of a
WBK17, the acquisition data file would contain data from twenty-four 16-bit channels.

Not user configurable. This column displays values for all enabled channels.

The Readings column will show, at most, one 16-bit value associated with the channel.
