Clamp-On Current, 20 Hz - 50 kHz
Models EM-6980 and EM-6981 are capable of measuring signals and noise superimposed on power currents up to 300 A from DC to 400 Hz. Intermodulation effects on the current probe outputs are also negligible. The EM-6980 and EM-6981 can be connected to a conventional oscilloscope, voltmeter or interference analyzer by means of a coaxial cable, such as Electro-Metrics EM-1106 or EM-1305 (not included with probe). Each current probe is calibrated for transfer conductance in a circuit having a 50 ohm resistive load. A serialized transfer impedance chart is supplied with each probe.
