SENT SPC is a half-duplex variation of SENT that uses Master Trigger Pulses to let one controller request data from multiple automotive sensors on a shared wire.
Dr. Eric Bogatin answers common ground bounce questions covering dI/dt, quiet-low measurements, return path discontinuities, via placement, TDR, and differential probing.
Understanding when to use a TDR, WavePulser 40iX, or VNA depends on bandwidth, rise time, port count, and whether you need time-domain impedance or frequency-domain S-parameters.
