Multiplier
After the signal is processed by the PreDivider, it is sent to the Multiplier. The Multiplier multiplies
the signal by an integer to increase its signal frequency, and then the signal is sent to the
PostDivider.
Parameter can be set as rising or falling edge. If a rising edge is set, each rising edge of the signal
coming from the PreDivider will be locked to match the signal of the rising edge, and vice versa.
During this process, make sure do not increase signal frequency via too larger multipliers to avoid
trigger signal frequency beyond the max. line rate of the camera. Even if a smaller multiplier is
selected, an excessively high frequency may be generated in the frequency adjustment, exceeding
the max. line rate of the camera.

PostDivider
PostDivider reduces signal frequency via an integer factor, and uses the newly generated frequency
signal as the camera's trigger signal.
Follow steps below to set frequency converter control.
Steps:
1. Click Frequency Converter Control, and select specific line or Encoder Module Out as Input
Source according to actual demands.
2. Set Rising Edge or Falling Edge as Signal Alignment according to actual demands.
3. Set PreDivider, Multiplier and PostDivider.

Parameters of trigger line rate and resulting trigger line rate may differ by camera models.

Trigger Line Rate: It refers to the external trigger raw line rate after filtering, and it only
involves external trigger signals.
