Abrégé

Disclosed is a diagnostic device for a seismic probe, the probe including, in an elongate tubular body, an electronic module, a capacitor bank and a spark gap adapted to generate a shock wave in a wellbore, the device including at least one sensor adapted to measure at least one parameter of the shock wave over time. The sensor is fixed to an inner surface of a wall of the tubular body, at a predetermined, non-zero distance from the spark gap in the direction of the electronic module. Also disclosed is a diagnostic method using the signals of the sensor.
