|NI-DCPower (English | Japanese)|
Aperture time is the period during which an ADC reads the voltage or current on a power supply or SMU. Aperture time can be specified in seconds (s) or power line cycles (PLCs). Measurement resolution, measurement speed, and frequency rejection are all functions of aperture time.
|Tip Select longer aperture times to improve measurement resolution; select shorter aperture times to increase the measurement speed.|
Use the niDCPower Configure Aperture Time VI or the niDCPower_ConfigureApertureTime function to set the aperture time of the device. Use the niDCPower Configure Power Line Frequency VI or the niDCPower_ConfigurePowerLineFrequency function to set the power line frequency for a specified channel of the device.
