IDS peak 2.8.0 / uEye+ firmware 3.33

This chapter contains the descriptions of all supported features from the PWM Control category.

The PWM (pulse-width modulation) is a module that generates pulses inside the camera. These pulses can be the source for different purposes, e.g.:

•LineSource for flash control

•TriggerSource for a freerun-like image capture mode

With PWMTriggerSource and PWMTriggerActivation you can define, which internal signal enables and disables the PWM. E.g. if you choose "AcquisitionActive", the PWM signal is generated from AcquisitionStart until the image acquisition is stopped. If you choose "ExposureActive", the PWM is only generated during image exposure.

The PWMFrequency defines the number of pulses per second (Hz). PWMDutyCycle controls the percentage of the pulse that is "HIGH".
