# How are GR detectors powered?

## USB

GR detectors are powered directly via a USB connection.

It is recommended that you use the power cable supplied by Kromek with the length of 1m to preserve data quality.

Make sure to leave 60 seconds before taking measurements to allow for the high voltage ramp up.
