The following diagrams illustrate the DRM and how it is deployed in the ice.

Internally, the DRM contains electronics to perform complex triggering to detect the pulse, to digitize the pulse at a gigahertz, to time the pulse to about a nanosecond, and to transmit it to the surface.

The signal is dipole antenna signal is split for digitization and for complex trigger logic that we expect to reduce the number of pulses seen by the antenna from a MHz to ~25 Hz triggers.
