Waveform Manager Plus - version 4

ADVANCED WAVEFORM CREATION, EDITING & MANAGEMENT

Version 4 of this highly regarded Windows program includes support for the latest TTi
generators and for LAN interfaces where fitted.
Direct import from CSV files has been added along with improved I/O functions and support
for the latest Windows operating systems.

WAVEFORM BUILDING TOOLS

TOOLKIT

Waveforms can be built in any number of sections using any combination of the following:
Standard waveforms, mathematical expressions, drawn waveforms, uploaded waveforms,
imported waveforms, existing stored waveforms.
Note: Waveform section limits can be defined via moveable cursors which can be dragged or
positioned numerically.

STANDARD WAVEFORMS

The following waveforms are available directly from the Waveforms dialogue box: Sine,
square, triangle, pulse, ramp, sinc [sin(x)/x], gaussian, exponent, noise, and cardiac*.
Note: The mathematical expression for any standard waveform can be examined by opening
the expression editor window.

EXPRESSION EDITOR FUNCTIONS

The following mathematical operators are available within the expression editor: Add,
subtract, multiply, divide, xn, sin, cos, arcsin, arccos, abs, log10, loge, en, square root, floor,
ceiling, random, pulse, in conjunction with constants and waveforms.
Note: The expressions used for each section of a waveform are retained and can be displayed
in a drop-down window.

EXPRESSION LIBRARIES

The mathematical expressions used for waveform creation can be stored in libraries. A default
library is created for each project which includes a number of useful examples including
waveshapes and modulations.

WAVEFORM DRAWING FUNCTIONS

Waveforms can be created or edited using freehand drawing and/or point to point line
drawing.

SMOOTH

Waveforms can be smoothed using a running average filter. Start and end points can be
specified as well as the number of points to average.

WAVEFORM EDITING/CONVERSION

TOOLKIT

All of the waveform building tools previously mentioned can be used to edit existing
waveforms. In addition waveforms can be manipulated directly using the following functions:

RESIZE WAVEFORM

Allows a waveform to be resized horizontally to any length between 4 and 1M horizontal
points.
Note: The vertical resolution of a waveform is automatically adjusted when it is downloaded
to the target. Thus an 8-bit waveform from a DSO will be expanded to 12-bits if it is
downloaded to a 12-bit generator (and vice versa).

WAVEFORM MATHEMATICS

The Waveforms Maths function allows waveforms to be combined and manipulated
independently of the expression editor. Waveforms can be scaled, offset, added, subtracted or
multiplied using dialogue boxes.
Note: Waveforms can also be combined and manipulated within the expression editor giving
access to the full range of mathematical functions.

INPUT/OUTPUT FUNCTIONS

FILE FORMATS

Waveforms can be read from and saved as any of the following formats: WFM (binary), NRM
(normalised data in ASCII), WAV (WaveCAD), ASC (WaveCAD), DSF (Tektronix DSO).

WAVEFORM DOWNLOAD/UPLOAD

Waveforms can be downloaded/uploaded to/from TTi arbitrary generators using either an
RS232, GPIB (IEEE-488), USB or LAN interfaces dependant on which interfaces are fitted to
the target generator.
Where COM ports are used, version 4 allows the use of any port from COM1 to COM256.
On TGA1210x and TGxx11 generators, a Flash memory device can be used for the transfer
instead of the digital interfaces.

DIRECT .CSV IMPORT

A general purpose csv parser is incorporated which allows import of any detected column of
data in a csv (comma separated variables) file.
This is the most widely used format for storing data that can be represented graphically. A
graphical preview is offered before confirmation.

CLIPBOARD FUNCTIONS

Waveforms can be imported to the program and exported from the program using the
Windows Clipboard.
Waveform import uses the “Text” clipboard format (i.e. numeric lists). This enables waveforms
to be imported from spreadsheets such as Excel and from mathematical programs such as
MathCad. Values are automatically normalised and re-scaled.
Waveform export creates multiple clipboard formats of Text (normalised numeric values
between ±1), Bitmap (as per on-screen display) and Picture (metafile retaining waveform
vector properties).
Note: Pictures or bitmaps can be pasted into programs such as Word for documentation
purposes.

DISPLAY AREA AND PRINTING

Multiple waveform windows can be open simultaneously. Each window is fully scaleable.
Variable zoom is provided with panning from a “navigator” sub-window.
Waveform section limits can be defined via moveable cursors which can be dragged or
positioned numerically.
Waveforms can be printed with automatic annotation and scaling.

MANAGEMENT AND UTILITIES

PROJECTS

To maintain good housekeeping, waveforms can be organised into “projects” with separate
directory structures. Each project maintains its own library of expressions. Waveforms and
expressions can be imported and exported from other projects.

INSTRUMENT SETUP

The instrument setup screen enables options for the waveform generator to be set from the
program. Examples of settable options are output amplitude, clock frequency and trigger
source.

HELP

Full on-screen Help is available with a hyperlinked contents table.

OPERATING SYSTEMS

Waveform Manager Plus version 4 is compatible with all version of Windows
from Windows 2000 through to Windows 7, and including 64 bit versions.

* Notes re Cardiac waveforms (version 4.01 onwards) :
Cardiac waveforms can be specified in terms of P, Q, R, S and T wave amplitudes, PR interval and
segment, QRS duration, Ventricular activation time, QT interval and ST segment.
