-221 Settings conflict; PWM
deviation decreased due to pulse
parameters
The PWM deviation must follow the limitation
concerning the pulse width or duty cycle, edge time,
and period (see Pulse width modulation waveform for
details). The waveform generator will adjust it
automatically.
-221 Settings conflict; frequency
forced duty cycle change
In the square wave function, if you change the
frequency to a value that cannot produce the current
duty cycle, the duty cycle will be automatically
adjusted to the maximum value for the new
frequency.
-221 Settings conflict; marker
forced into sweep span
The marker frequency must be a value between the
start and the stop frequency.
-221 Settings conflict; selected
arb is missing, changing selection
to default
If you delete an arbitrary waveform after storing its
instrument state, you will lose the waveform data and
cannot generate the waveform. The built-in
exponential-rise wave is generated instead.
-221 Settings conflict; offset
changed due to amplitude
When the existing offset voltage does not conform to
the following limitation: |Voffset| + V peak-to-peak / 2
≤ Vmax, it is adjusted automatically to the maximum
DC voltage allowed with the specified amplitude.
-221 Settings conflict; amplitude
changed due to offset
When the existing amplitude does not conform to the
following limitation: |Voffset| + V peak-to-peak / 2
≤
Vmax, it is adjusted automatically to the maximum
value allowed with the specified offset voltage.
-221 Settings conflict; low level
changed due to high level
The high level must always be greater than the low
level. If you specify a high level that is smaller than
the low level, the instrument will adjust the low level
to be 1 mV less than the high level.
-221 Settings conflict; high level
changed due to low level
The high level must always be greater than the low
level. If you specify a low level that is greater than
the high level, the instrument will adjust the high level
to be 1 mV greater than the low level.
-222 Data out of range; value
clipped to upper limit
The specified parameter is out of range and is
adjusted to the maximum value allowed.
-222 Data out of range; value
clipped to lower limit
The specified parameter is out of range and is
adjusted to the minimum value allowed.
-222 Data out of range; pulse edge
time limited by period; value
clipped to upper limit
The specified edge time does not conform within the
existing period and is adjusted to the maximum value
allowed.
-222 Data out of range; pulse width
time limited by period; value
clipped to...
The specified pulse width does not conform to the
following condition and is adjusted to accommodate
the period: Pulse Width
≤ Period – (1.6 x Edge
Time).
-222 Data out of range; pulse duty
cycle limited by period; value
clipped to...
The specified duty cycle does not conform to the
following condition and is adjusted to accommodate
the period: Duty Cycle
≤ (1 – 1.6 x Edge Time /
Period) x 100%.
-222 Data out of range; large
period limits minimum pulse width
The minimum pulse width is larger (for pulse
waveforms with a period larger than 10 s). Refer to
Pulse waveform for details.
-222 Data out of range; pulse edge
time limited by width; value
clipped to...
The specified pulse edge time does not conform to
the following condition, and is adjusted to
accommodate the pulse width: Edge Time
≤ 0.625 x
Pulse Width.
