Creating an Arbitrary Waveform
You can create an arbitrary waveform using the following methods:
Enter individual data points
Draw lines between data points
Create a predefined waveform
Export a waveform from software
Create data points using SCPI commands
The waveform’s frequency and amplitude are influenced by the number of data points and their value
in the waveform. For further information on how the number of data points influence the frequency
and amplitude of a waveform in execution memory, see Setting the Frequency section (on page 32) and
Setting the Amplitude section (on page 33), respectively.
Entering Individual Data Points
The most basic way to program an arbitrary waveform is to enter data points for the waveform, one
data point at a time. While this can become tedious, the auto-increment function helps this process.
To enter individual data points into waveform memory, follow these steps:
1.
Press
WAVE
main key to display the selection menu.
2.
Press F5: ARB to display the arbitrary menu.
3.
Press F4: EDIT to display the Edit menu.
4.
Press F1: POINT to select the point-by-point programming mode.
5.
Press F1: ADRS.
6.
Use the rotary knob or the numerical keypad to enter the address.
7.
Press F2: DATA.
8.
Use the rotary knob or the numerical keypad to enter the value for the data point. Valid
entries range from –8191 to 8191.
9.
Repeat steps 5 through 8 for additional points until you finish creating your arbitrary
waveform.
