Defining Equations
The following procedure shows how to define, compile, and output a waveform
using an equation to generate a waveform file. You might want to view the
output waveform on an oscilloscope to verify its shape (sine wave) and period
(1 ms).
. Do not use CR (0x0D) as a terminator in your equation file. Use only
LF (0x0A).
1. Define the waveform file. Use the following command
EQUATION:DEFINE "new.equ",#224range(0,1s)<LF>sin(2*pi*x)<LF>
to define an equation file named “new.equ” that produces a one-cycle sine
wave when compiled.
2. Set the number of waveform points. Use the following command
EQUATION:WPOINTS "new.equ",128
to set the number of waveform points to 128 for the "new.equ" equation
file.
3. Compile the new.equ" equation file to generate a waveform file named
new.wfm." Use the following command
EQUATION:COMPILE EXECUTION,"new.equ"
to compile the equation file. A waveform file called "new.wfm" will be
loaded into memory.
4. Select the new.wfm" file for output. Use the following command
WAVEFORM "new.wfm"
to select the new.wfm" file.
5. Turn on the WAVEFORM OUTPUT connector. Use the following command
OUTPUT:STATE ON
to turn on the output. The LED beside the WAVEFORM OUTPUT connector
turns green to show the output is active.
