1.2.5 PATTERN GENERATION, EXAMPLE 2

To generate a 100 point voltage complex waveform comprised of 1/4 cycle sine wave and 1/4 cycle trian-

gle wave with an amplitude of 10 volt peak to peak riding on 0 volt level, and a total duration of 1 second,

enter the parameters listed in Table 2.

By using combinations of the four basic waveform types, complex waveforms can be generated, and

repeated using the Pattern Execution window (see PAR. 1.2.6) to provide great flexibility in determining the

output.

1.2.6 PATTERN EXECUTION

The Pattern Execution window (Figure 11) allows the program established by the pattern generation win-

dow to be executed. If the Loop Direction is set to UP, the Loop From window establishes the point in the

loop that will start repeating. For example, if the list is 10 points, and Loop From is set to 3, the first 2

points would only be executed once, and the points from 3 to 10 would be repeated the number of times

specified in the Loop Count Window. If Loop Count is set to 0 the program will run continuously until

stopped by the user. The RUN button starts the program. While the program is running the Running indi-

cator is on and the RUN button changes to a STOP button used to halt the program. When the program is

halted, the unit reverts to the settings in effect prior to issuing the RUN command.
