Front-Panel Menu Operation Introduction
For this example, you will specify a pulse width and pulse width deviation for a 1 kHz pulse waveform with a 5Hz sine
wave modulating waveform.
1. Select the carrier waveform parameters.
Press Waveforms and then press Pulse. Use the Frequency, Amplitude, Offset, Pulse Width and Edge
Times softkeys to configure the carrier waveform. For this example, select a 1 kHz pulse waveform with an ampli-
tude of 1 Vpp, zero offset, a pulse width of 100 µs, and an edge time of 50 ns (both leading and trailing).
2. Select PWM.
Press Modulate and choose Type, then PWM. Then press the first softkey (Modulate) to turn modulation on.
Notice the status message "PWM Modulated by Sine" in the upper-left corner of the display.
3. Set the width deviation.
Press the Width Dev softkey and set the value to 20 µs using the numeric keypad or the knob and cursor keys.
4. Set the modulating frequency.
Press the PWM Freq softkey and then set the value to 5 Hz using the numeric keypad or the knob and cursor
keys.
5. Select the modulating waveform shape.
Press Shape to select the modulating waveform's shape. For this example, select a sine wave.
