To Output a PWM Waveform
You can configure the function generator to output a pulse width
modulated (PWM) waveform. The Keysight 33210A provides PWM for
pulse carrier waveforms, and PWM is the only type of modulation
supported for pulse waveforms. In PWM, the pulse width or duty cycle of
the carrier waveform is varied according to the modulating waveform.
You can specify either a pulse width and width deviation, or a pulse duty
cycle and duty cycle deviation, the deviation to be controlled by the
modulating waveform.
For this example, you will specify a pulse width and pulse width
deviation for a 1 kHz pulse waveform with a 100 Hz sine wave
modulating waveform.
1 Select the carrier waveform parameters.
Press
and then press the
Freq
,
Ampl
,
Offset
,
Width
, and
Edge Time
softkeys to configure the carrier waveform. For this example, select a 1
kHz pulse waveform with an amplitude of 1 Vpp, a zero offset, a pulse
width of 100
µ
s, and an edge time of 50 ns.
2 Select PWM.
Press
(PWM is the only modulation type for
Pulse
). Notice that a
status message "PWM by Sine" is shown in the upper-left corner of the
display.
3 Set the width deviation.
Press the
Width Dev
softkey and set the value to 20
µ
s using the numeric
keypad or the knob and cursor keys.
