    (www.microchip.com). LOW-FREQUENCY BODE PLOT MEASUREMENTS The dsPIC33CH512MP506 device, along with an additional on-board circuitry, allows Bode plot measurements to be performed without the need for an isolation transformer. The transformer might still be required if the injected signal tends to be at a very low frequency (for instance, in case of Power Factor Correction (PFC) applications).
