Operating Basics Multiple Editor Windows The AWG610 Arbitrary Waveform Generator can open and edit up to three waveform and/or pattern files, in any combination. The wave data is displayed in separate windows, with each window stacked vertically on the screen. Multiple editor windows are very useful for creating a new waveform by cutting and pasting waveform data from other files. Figure 2–23 shows an example of three opened editor windows (one pattern and two waveform files).

Operating Basics 2. Select a waveform or pattern file from the Select File list. If necessary, use the Drive... side menu to select the storage drive where the file to load is located. 3. Push the OK side button. The instrument opens a new window for the waveform or pattern data, stacking the windows vertically to fit on the screen. If you attempt to load a sequence, text, or equation file, you will receive an error message. Creating a New Waveform or Pattern in a Multiple Editor Window.

If you have not saved the data after modifications, the message box Save the changes you made? appears. Push Yes, No, or Cancel side button. Setup Overview The Setup screen is where you load and set up the waveform for output. This section gives you an overview of the Setup screen, how to load a file, how to set the signal output parameters, and how to enable signal output.

Operating Basics buffer, you must save the currently edited waveform, pattern, sequence or equation/text into a file. You can enter into the QUICK EDIT mode only from the waveform editor. When you enter into the quick edit mode, the instrument copies the data in the edit buffer into the undo buffer. All the changes you make immediately reflect to the data in the edit buffer, and also to the data in the waveform memory if that data is being loaded to output.
PAGE 75
Operating Basics Editing a Waveform To edit the loaded waveform file, push the Edit... side menu button. The instrument opens the appropriate edit window for the previously loaded file type. If you have not loaded a file in the Setup screen, the instrument displays the message No output data, and you cannot enter into the editor. The editors are described in more detail in the Reference section beginning on page 3–45.

Operating Basics Saving and Restoring Setup Parameters The waveform or pattern file contains only the waveform and clock information. When you load a waveform or pattern file, the output signal will use the current instrument setup parameters. To save you from doing a manual setup procedure each time you load a waveform, the AWG610 Arbitrary Waveform Generator lets you save setup parameters into a setup file. You can then restore the saved settings for use with waveforms.

Capturing Waveforms This section explains how to transfer waveforms from the instruments to the AWG610 Arbitrary Waveform Generator using the GPIB interfaces. The AWG610 Arbitrary Waveform Generator captures the waveform data acquired in oscilloscopes and/or generated in generators over the GPIB interface without control by an external controller. The waveforms captured are automatically converted to waveforms that the AWG610 Arbitrary Waveform Generator can handle.

Waveform Programming Language This section describes the Waveform Programming Language (WPL) syntax, rules, and command descriptions. There are also a number of programming examples at the end of this section. Command Syntax This manual uses the Backus-Naur Form (BNF) notation, shown in Table 3–46, to describe commands.
PAGE 294
Waveform Programming Language UserĆDefined Variables All user-defined variable names must satisfy the following requirements: The first character must be an alphabetical character. The rest of the name must consist of an alphabetical character(s), digit(s), and/or an underscore(s) (_). The maximum number of characters is 16. All characters in excess of 16 are ignored. Variables that have the same first 16 characters will be regarded as identical. Alphabetical characters are case-insensitive.
PAGE 295
Waveform Programming Language Waveform Files Some commands accept a waveform file name enclosed in double quotes. For example: ”sinewave.wfm” . Observe the following rules when using waveform expressions in equations: A quoted string can include any character defined in the 7-bit ASCII character set. A numeric value can be embedded in a string in the following format: “AA”:i:“.WFM” If the value of i equals 10, the string “AA10.WFM” will result.
PAGE 296
Waveform Programming Language In a waveform expression, the data length of the file created and the clock information are determined as follows. If is a marker: If the output file does not already exist, an error will occur. Attributes such as the data length (output file size) and clock information are unchanged. The analog data section does not change. Neither the size or the close variable value is used.
PAGE 297
Command Descriptions The WPL commands are listed in alphabetical order. Mathematical functions and operators are described under the headings Math Functions on page 3–190 and Math Operators on page 3–192.

The first argument is the file to which the strings specified as the second argument and after will be written. The string must be enclosed in double quotation marks. If you desire to use a variable as a string, you must place the colon (:) before and after the variable. For example: ”text”:i:”.

However, this viewer cannot display the sequence. Use the sequence editor to confirm the results. Example 4 The following example shows how to use boolean relational operations between a waveform and its marker data. delete(”MOD01.WFM”) delete(”MOD02.WFM”) “Mod.wfm” = sin (2 * p * scale) ”MOD01.WFM” = ”MOD.

Programming Examples The following text describes what happens in this example: 1. The noise() function generates a noise waveform into the file NOISE.WFM, in which the waveform data are normalized using the norm() function. 2. The extract() function extracts the first 7 data and stores them into the file TEPM1.WFM. 3. The integ() function integrates the 7 data. The data of last point is the amount of 7 point data.

Appendix C: Inspection and Cleaning Inspect and clean the instrument as often as operating conditions require. The collection of dirt can cause instrument overheating and breakdown. Dirt acts as an insulating blanket, preventing efficient heat dissipation. Dirt also provides an electrical conduction path that can cause an instrument failure, especially under high-humidity conditions. To prevent damage avoid the use of chemical cleaning agents that might damage the plastics used in this instrument.
PAGE 426
Appendix C: Inspection and Cleaning Cleaning Procedure Ċ Exterior To avoid injury or death, unplug the power cord from line voltage before cleaning the instrument. To avoid getting moisture inside the instrument during external cleaning, use only enough liquid to dampen the cloth or applicator. 1. Remove loose dust on the outside of the instrument with a lint-free cloth. 2. Remove remaining dirt with a lint free cloth dampened in a general purpose detergent-and-water solution.

Appendix F: Miscellaneous This appendix covers the following items. Sampling theorem Differentiation Integration Convolution Correlation Code Conversion Sampling Theorem When the signal is continuous and the highest frequency component of the signal is f 0, sampling with Tx f0/2 loses none of the data contained in the signal. T is the sampling interval. This theorem is well known as the sampling theorem. If data is created to meet this theorem, the necessary signal can be obtained.
