Figure 9: The RNG tab of the quCNT module.
This tab of the quCNT module can be used as a random number generator if at least
three dierent APDs (channels 0, 1, and 2) are installed in your hardware. You can toggle

between APD 0 and APD 1 is then interpreted as a zero bit and a coincidence event
between APD 0 and 2 as a one bit.
Warning: For the time the RNG mode of the quCNT module
is enabled, there will be no new count rates displayed in the
rst or second tab of this module.
