Operating Basics 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. Refer to The Setup Menu Screen in the Reference section of User manual for more information. Main Setup Screen Push the SETUP front panel button to display the main Setup screen. See Figure 2–23. Table 2–13 describes the screen waveform parameter icons.
Operating Basics Table 2-13: Setup screen parameter icons Icon Description Displays the file name of the waveform, pattern, or sequence file loaded for output. Icon Description Displays the noise signal level added. Note: Use the View button to display the loaded waveform. Displays the lowĆpass filter setting through which the waveform is passed. (except option 02) Indicates that the channel output is enabled or disĆ abled. If the switch is shown open, that channel output is disabled.
Operating Basics Composition and Setup of Output Channel Use the Setup menu to set up parameters for each channel as well as the instrument. Set up the file to load, amplitude, and run mode for each channel. Set up the Horizontal, Run Mode, and Trigger for the instrument. Loading a Waveform File to Output Do the following steps to load a waveform file into the Setup screen: 1. Push the Waveform/Sequence bottom menu button. This opens the Waveform/Sequence side menu. 2. Push the Load... side button.
Operating Basics buffer are completely independent. So, you can edit a waveform, pattern, sequence or equation/text while outputting an another waveform or sequence. However, when you push SETUP (front panel) Waveform/Sequence (bottom) Edit (side) to copy the waveform in the waveform memory to the edit buffer, you must save the currently edited waveform, pattern, sequence or equation/text into a file. You can enter the QUICK EDIT mode only from the waveform editor.
Operating Basics Note that the view function always display the waveform in the file that you specified, but not the waveform in the waveform memory. Even when you change the waveform with the editor and update the waveform memory, the view function still displays the waveform before the update unless you do not save the file. Setting Waveform Output Parameters The Setup side menus provide commands for setting and adjusting waveform output parameters.
Operating Basics Table 2-15: Setup output parameter operations (cont.) Bottom button Side button Description Horizontal Clock Sets the clock sample rate from 10 kS/s to 200 MS/s. Clock Src Sets the clock source to either Internal or External. When set to Internal, 10 MHz internal reference clock is used. When set to External, a valid external clock signal is DC to 200 MHz with a voltage level of 0.4 VpkĆpk and up to ±2 V. Clock Ref Sets the reference clock source to either Internal or External.
Operating Basics Saving and Restoring Setup Parameters The waveform or pattern file contains only 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 AWG710 Arbitrary Waveform Generator lets you save setup parameters in a setup file. You can then restore the saved settings for use with waveforms.
