AWG610 Arbitrary Waveform Generator User Manual
Table D-12: Pulse width modulation
File name PWM.WFM Made with waveform editor
Descriptions The waveform editor is used to create a ramp wave of 1000 periods
and a sine wave of 1 period, and these two waveforms are compared
to create the PWM.WFM waveform.
Settings Waveform points: 32000, Clock frequency: 1.0 GHz, Output time: 32 m s
Table D-13: PseudoĆrandom pulse
File name PRBS9.WFM Made with waveform editor
Descriptions An MĆseries pseudoĆrandom signal is created using the waveform
editor's timing display shift register generator function.
Register length = 15
The encoding is NRZ.
Settings Waveform points: 4088 ((2

-1) x 8), Clock frequency: 2.0 GHz,
Output time: 2.044 m s
Table D-14: Waveform for magnetic disk signal
File name DSK.WFM Made with disk application
Descriptions Creates a disk signal pattern with NRZĆI modulation using the disk
application. This signal is created with default parameter settings.
