Configure Arbitrary Waveform
There are two ways to generate arbitrary waveforms. Users can output an arbitrary waveform selected from the built-in selection of predefined arbitrary waveforms, or create and output a user-defined waveform by specifying point by point arbitrary data using the
EasyWave software. This section will explain how to do both.
Generate Predefined Built-in Waveforms
There are a total of 41 (including sine, square, ramp, pulse, and noise) predefined built-in arbitrary waveforms that can output from the generator. They are divided into four categories: Common waveforms, math waveforms, project waveforms, and
Windowing/trigonometric waveforms.
Common Waveforms
Common waveforms consist of:
StairUp
Upward staircase
StairUD
Math Waveforms
Up and down staircase
StairDn
Trapezia
Downward staircase
Trapezoidal
Math waveforms consist of:
ExpFall
LogFall
Sqrt
Exponential fall
Logarithmic fall
Square root function
Sinc
Dlorentz
Lorentz
Sinc function
D-lorentz function
Lorentz function
Gmonpuls
Gaussian mono pulse
ExpRise
LogRise
X^2
Exponential rise
Logarithmic rise

Window and Trigonometric Waveforms
Quake

Earthquake
Sine with white noise
Window and trigonometric waveforms consist of:
Hamming
Hamming window

Follow the steps below to browse and select a predefined arbitrary waveform.
1. Setup the instrument to access the arbitrary waveform function menu.
2. Select Built-in from the parameter menu and there will be a table on the display area and four categories to select from the parameter menu. Select Common to browse the common waveforms. Select Math to browse the math waveforms. Select
3. After making the selection, use the rotary knob to select the desired predefined waveform.
Project to browse the project waveforms. Select Win/Trig to browse the window and trigonometric waveforms.

4. Once selected, press the Done option from the menu.
5. The generator will return to the main Arb parameter menu and the waveform display area will show the waveform shape of the selected predefined arbitrary waveform. For example, the screenshot below shows the display of the predefined
Cardiac signal.
6. Adjust frequency, amplitude, etc. as needed.
Generate User-Defined Waveforms
The generator has built-in non-volatile memory to store up to 32 user-defined arbitrary waveforms, 24 with a maximum of 16k points and 8 with a maximum of 512k points.
Note: Channel 1 can recall both, 16k point and 512k point waveforms, but is limited to output only 16k point waveforms natively. Recalled 512k point waveforms will be downscaled and interpolated to 16k point waveforms. Channel 2 can recall both, 16k point and 512k point waveforms natively.
To create an arbitrary waveform, users must use the USB interface in the rear panel for PC connectivity to the EasyWave software, which can be downloaded at www.bkprecision.com
.
Note: EasyWave software supports Windows XP/Vista/7/8 (32 bit and 64 bit) only.
