  • Page 100 Operating basics Basic operations The following steps explain basic waveform creation and other useful functions that are available with ArbExpress. To create a new waveform, use the File menu. Blank sheet opens a blank sheet in the window with 1024 points waveform length. You can change the number of points using Properties...
  • Page 101 12. Calculation results are displayed in the Resultant Waveform pane. This is an example of adding noise to a square waveform. 13. You can remotely control Tektronix AWG/AFG instruments using ArbExpress. From the Communication menu, select AWG/AFG File Transfer & Control... to display the dialog box.
  • Page 102 Operating basics Using CSV format ArbExpress allows you to convert a CSV (Comma Separated Value) format file, which is created by Microsoft Excel, to waveform data that is compatible with waveform data the instrument. Create a CSV file to use with ArbExpress. Enter point or time to this column.
  • Page 103 Operating basics Save the waveform as the .tfw format. Copy the waveform data to a USB memory and load the waveform in the arbitrary function generator. The AFG3000 series instruments output recalled waveform data. This is an example of the oscilloscope screen. Fs represents setting frequency of output waveform.

  • Page 105: Application Examples

    Application Examples This section contains a series of application examples. These simplified examples highlight the features of the instrument and give you ideas for using it to solve your own test problems. Lissajous Patterns Use your AFG3000 series dual-channel model to create a Lissajous pattern and observe the waveforms with an oscilloscope.
  • Page 106 Application Examples Connect the CH1 and CH2 Outputs of the dual-channel instrument and the CH1 and CH2 Inputs of an oscilloscope with BNC cables. Set the waveform parameters as follows: Sine (Continuos) Amplitude: 1 V CH1 Frequency: 400 kHz CH2 Frequency: 500 kHz Set the oscilloscope display format to XY.
