Signal Multiplier: Transmitter Output or Receiver Amplification?

Software

Hi everyone,

I have a question about the Signal Multiplier configuration parameter. Specifically, I’m trying to understand whether the Signal Multiplier affects the signal output of the transmitter (e.g., laser diode) or if it refers to the amplification of the signal on the receiver side (e.g., photodetector/amplifier).

From my experience, signal multipliers are often associated with receiver-side amplification. However, the documentation mentions that increasing the Signal Multiplier imposes limitations on the azimuth window, which seems to imply adjustments on the transmitter side—for example, reducing laser activity to manage power and thermal behavior.

Could someone clarify if this parameter is indeed related to the transmitter, or am I missing something here?

Thanks in advance for your help!

Great question! You are absolutely spot on with your deduction.

The Signal Multiplier parameter acts on the transmitter side. When you increase the signal multiplier (e.g., to 2x or 3x), the sensor achieves a higher Signal-to-Noise Ratio (SNR) and extended range by firing 2x or 3x as many laser pulses as baseline. Because firing more laser pulses increases both power consumption and thermal load, the sensor must reduce the active firing area to stay within its safe operational limits. This is exactly why increasing the Signal Multiplier imposes restrictions on the azimuth window.

Your understanding of the power and thermal management behavior was perfectly correct!

I hope this helps.
