Performance and troubleshooting
Value changes by feature interdependencies
The conversion between time and clock cycles affects control values. Features for
pixel format, bandwidth, ROI, exposure time, and triggering are related to each
other. Changing values for one feature can change values for another feature. For
example, frame rates can be reduced when
PixelFormat is changed subsequently.
Figure 120 shows the interdependencies.
Effects for the interdependent features
Changing one control's value affects other control's values, such as:
If:
Height value is changed.
Then: Other values may be affected, such as for
AcquisitionFrameRate and
ExposureTime.
We recommend you to consider:
• The more features you adjust, the more current values deviate from previously
set values.
• The same effects that apply to
ExposureTime, also apply to AutoExposure.
• To avoid readjustments, apply settings in the order shown in Figure 120.
Parameter changes in triggered mode
See Ignored triggers on page 290 for more information.
