For Power converter development and diagnostics. Following are some examples:
• In MOSFET or IGBT devices as small as TO-220 or TO-247 in case of the N7042A probe.
• In MOSFET or IGBT devices as small as TO-247 or around the terminals of large power
modules in case of the N7040A / N7041A probes.
• In bond wires in power devices
To measure power losses in semiconductors
To monitor currents in small inductors, capacitors, snubber circuits, etc
To measure small AC current on a conductor with high DC current or in the presence of a high DC
magnetic field. An example can be monitoring capacitor ripple.
To measure high frequency sinusoidal, pulsed, or transient currents from power frequency to rf
applications
To measure current in motor drives and in particular power quality measurements in VSD, UPS or
SMPS circuits
To evaluate switching performance of power switches (double pulse tester)
To measure high order harmonics
