Modulation Frequency
Last change: 30 June 2014
Version 2
The modulation frequency is set to 10 MHz per default. Other modulation frequencies can be set using the
register ModulationFrequency. Be aware that this also changes the ambiguity range of the camera.
In the register you can either write the frequency in 10 kHz steps or the index. On a read of the register you
get the current selected modulation frequency.
Other frequencies between 1,25Mhz and 20 MHz can be set as well, but as there is no calibration data
available for other frequencies than the above it may result in unpredictable distance values.
The modulation frequency has also impact on the maximum integration time. At 10 MHz the maximum
integration time is 52,6ms. At 20 MHz this maximum is reduced to the half of 26,3ms.
