Function
The FB has three function units:
l Trigger check
– Monitoring of the digital trigger source for a valid trigger event
l Processing of the measured signal
– Linking the measurement inputs
– Calculating the time base
– Monitoring of the analog trigger source for a valid trigger event.
l Measuring value memory
– Scaling the ring buffer
– Filing the measured data in the ring buffer
– Saving the measuring points for image generation
