SEN0463 - Geiger counter issue

In the specifications I read: “Signal output: digital output, pull down when a pulse is detected” but in the forum the opposite is confirmed. Which one is it?

 

The supply voltage is specified as “Supply voltage: 3.3V ~ 5V”. Is the pulse amplitude proportional to the supply voltage, or is it - hopefully - a constant 3.3V?

 

What is the length of the pulse in micro-seconds?  Does it depend on the dead-time of the tube? When I change the tube to some other tube with longer or shorter dead-time, does the pulse length change?

1. Yes, the level of the pulse is VCC.
2. The pulse length I think is uncertain, the greater the radiation the shorter the interval must be. The sensor just outputs a low level when it receives ionizing radiation.
