ULF instrument

The ULF instrument for measuring electric and magnetic fields in the ULF frequency range is designed for collecting and processing information on 3 components of magnetic field and one component of electric field. The instrument provides the analog and digital processing of the magnetic and electric field signals through the telemetry system (STS).
Three-component magnetic sensor is a component of the instrument KEM (Czech Republic).

Operational modes:

1. Transmission of all 4 components with the rate of 20 kbits/s or 40 kbit/s with the digitizer frequency of 280 Hz.
2. Transmission of one selected component for the telemetry rates 5 or 1.25 kbit/s with the digitizer frequency 70 Hz.
