Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

The first installment of this article series discussed the need to verify SPICE model accuracy and how to measure the open- and closed-loop small-signal AC output impedance of operational amplifier ...

You can purchase test equipment that will allow you to examine the loop gain and loop phase properties of an operating feedback loop and, that purchased equipment will deliver useful results over a ...

It’s impossible to directly measure the stability (gain/phase) characteristics of a device if the device’s control loop lacks an access point to apply a test signal or can’t be broken. For many of ...
