Electronic 12V transformer to supply a halogen lamp. Amplitude modulated 150 kHz carrier with 100Hz envelope. > Amplitude spectrum with the help of the HRM100 harmonic analysis. The burst fire presents a 1.56Hz modulation of the carrier (50Hz mains voltage). The DC component of the spectrum results from the blower motor in half-wave operation. The extended X-TrigӔ trigger mode detects the 1.56Hz periodicity which is used for synchronisation.Using the plot function the half-wave trms values U > l are plotted over time (lower curve B). Irregular sags of about 8V can be recognised. The momentary...
