Waveform Manager Pro


Waveform Manager Pro is the ideal tool to compose annotated pictures from waveforms, screen images, and meter measurements taken from your scope, spectrum analyzer or network analyzer. It operates as a powerful stand-alone program, or as a front-end for your favorite word processing, graphics or desktop publishing package.  Waveform Manager will also read and write data to and from circuit analysis tools such as LTSpice / SwCAD III. Whether you're documenting problem signals, preparing service reports for customers, or just printing waveform pictures, Waveform Manager's easy operation combined with complete document archival and high-quality picture transport via drag and drop or the Windows Clipboard will make your chores a pleasure.

Transfer Data to/from your instrument via your PC serial, GPIB or Ethernet port

Waveform manager works with the four types of data most commonly available from your instrument including waveforms, screen images, meter measurements and setups.  Now with V4.0 you can import vector (complex) data, datasets consisting of multiple records and data on logarithmic sample intervals.  All data types can be transferred once on command or refreshed automatically on a schedule, or when the scope triggers.

Display multiple waveforms at once in one or more waveform windows with drag and drop placement together with magnification facilities to easily highlight waveform details.  Options allow you to force disparate waveforms to be displayed on common time scales or magnification settings.

New features in V4.0 include Polar, Smith Chart and 3D rectangular chart views.  2D rectangular views now offer classic scope and spectrum analyzer graticule styles along with numerous options for chart labeling and reference symbols.  Horizontal scales of rectangular charts may be scaled logarithmically or linearly.


3D Data

3D data (multiple records in a single data set) can be displayed in either a 2D or 3D view.  Navigation buttons enable you to move forward and back within the data set.  With a 2D view a single record (the current record) is displayed at any given time.  In a 3D view the current record is the foremost waveform and the number of records displayed behind it can be adjusted up to a maximum of 249.  3D views support a "trackball" mouse interface that behaves as if the view were contained within a sphere and the mouse "touches" the front of the sphere to rotate it as one would rotate a trackball.  Both perspective and orthogonal projections are available.

Measurement and Analysis

Full screen X and Y cursors

Use the cursors built-in to the waveform window to measure time and voltage differences on your waveforms.  12 different measurements make quick work of measuring difficult waveform features.

Up to 4 Markers per Waveform

Add markers to your waveform to denote 3dB points and other points of interest.  Marker information can be displayed in the readout bar along with cursor measurements.

Waveform Parameter Measurements

38 different waveform measurements take the tedium out of your analysis chores.   Measurements include common voltage and time/frequency types such as Peak to Peak and Rise Time.  New signal analysis measurements include SINAD, SFDR and ENOB.

Automotive measurements include Injector Peak Volts, Injector On time, Ignition Peak, Ignition Burn Time and Ignition Burn Voltage.

Many measurements can be gated to restrict the region of measurement to the area between the X cursors.  Thresholds and noise immunity can be set individually on each measurement.

Measurement results can be displayed in the dedicated Measurement Window, or placed in notes, window title bars or even as file labels.

Import/Export Waveforms as Tables

Waveform Manager provides programmable ASCII table export capabilities, making it easy to output your waveform data to spreadsheets or analysis programs.  Export to files or through the clipboard with your choice of CSV or tab delimiting.

File import includes support for LTSpice / SwCAD II plot outputs in all common analysis types, making it easy to compare signals from your scope or analyzer with those you simulate.  You can also send ASCII export data back to the Spice program for use in simulation.

Enhanced Screen Image Support

With version 4.0, colors in all monochrome and 256 color screen images can be modified with point and click ease.  This means that you can customize the colors of the vast majority of screen images available from instruments.

Also new with version 4.0 is support for HPGL plotter graphics.  This enables you to get screen plots from a wide variety of lab instruments that are not explicitly supported by using the program to emulate an HP 7475A plotter.  Epson ESC/P2 and HP PCL emulation is also included.

Waveform Database

User defined data fields together with database indexing and search capabilities enable you to customize the way you save your waveform information.  Define fields to track important customer data right along with you waveforms. If particular fields would be useful when looking up files later, designate them as file labels and they will be listed whenever you later go to open a file.

Clipboard Support/Drag and Drop

Select a display window and press the Copy toolbar button to send a picture of the window to the clipboard. Or drag and drop it directly into another application in either DIB (bitmap) or EMF (metafile) format.

Copy individual waveforms to the clipboard as pictures and data tables.

Screen Grab

Generic screen grab facility works with any instrument that prints screen pictures through a serial or GPIB port to an Epson ESC/P2 or HP PCL III printer. Program converts ESC/P2 and PCL codes to bitmap and displays in Image Window.  Bitmap image data (not ESC/P2 or PCL) can be exported.  ESC/P2 and PCL data can be imported and displayed. 

Program also can emulate an HP 7475 (HPGL) plotter. HPGL is displayed in vector format in the image window.  Pen colors can be specified and changed after plot is acquired.  For GPIB operations 7475 emulator can function in either Talk/Listen or Listen Only mode.  HPGL data import/export is supported.


Automatic Refresh

Transfers waveforms, measurements or screen images from locations you specify, or from all currently displayed locations. Can perform transfers when the scope triggers, or repeatedly with 1s to 24Hr wait time between. Can be used in conjunction with Capture to File for event logging based on trigger events, or for measurement logging. Also can be used with Screen Grab to automatically update display each time a print job is initiated from the instrument.

Capture To File

Saves waveforms transferred from an instrument into separately numbered files based on a seed name you supply. One file is saved after each transfer except for group transfers where waveforms may optionally be saved to separate files. Number of files is adjustable up to 10,000. File formats include WFD, BMP, PNG, JPEG, EMF.

Can also capture designated measurements in multiple columns to a single measurement log "TXT" file each time a waveform or measurement transfer occurs.


Print using any printer that has Windows support. You can suppress the printing of background colors, or convert the entire image to monochrome, for excellent results with laser and dot matrix printers. Using Print Preview you can adjust the size and location of the printed image on the page, and view colors and proportions as they will appear.

Easy Installation

Program identifies the currently connected instrument and automatically configures the serial port for successful communication. All of the user's guide is available in the on-line help.
