– If you select an arbitrary waveform as the modulating waveshape (“USER”), the
waveform is automatically limited to 4K points. Extra waveform points are
removed using decimation.
PWM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
PWM:INTernal:FREQuency? [MINimum|MAXimum]
Set the frequency of the modulating waveform. Used only when the Internal
modulation source is selected (PWM:SOUR INT command). Select from 2 mHz to
20 kHz. The default is 10 Hz. MIN = 2 mHz. MAX = 20 kHz. The :FREQ? query
returns the internal modulating frequency in hertz.
PWM:DEViation {<deviation in seconds>|MINimum|MAXimum}
PWM:DEViation? [MINimum|MAXimum]
Set the pulse width deviation in seconds. This value represents the variation in
width (in seconds) from the pulse width of the carrier pulse waveform. The default
is 10 μs. MIN = 0 s. MAX = 500 s (limited by the period, minimum pulse width, and
edge time). The :DEV? query returns the pulse width deviation in seconds.
– The pulse width deviation cannot exceed the current pulse width.
– The pulse width deviation is also limited by the minimum pulse width (Wmin):
Width Deviation <
Pulse Width – Wmin
and
Width Deviation <
Period – Pulse Width – Wmin
where:
Wmin = 40 ns for period <
10 s.
Wmin = 200 ns for period > 10 s, but <
100 s.
Wmin = 2 µs for period > 100 s, but <
1000 s.
NOTE
Arbitrary waveforms are optionally available with the 33210A (Option 002). To
