This instrument is also known as an induction magnetometer, pulsation magnetometer, or micropulsation receiver. It is described in Engebretson et al., "A conjugate study of Pc 3-4 pulsations at cusp latitudes: Is there a clock angle effect?", J. Geophys. Res., Vol. 105, pp. 15965-15980, 2000.

Below, a postnoon ULF spectrogram indicates a distinct group of Pc-1 bursts from 14 to 16 UT (12 to 14 MLT) possibly associated with a dayside FTE.
