Keysight N2780B Series AC/DC Current Probes A wide selection of current probes to meet your applications needs Data Sheet02 Keysight N2780B Series AC/DC Current Probes A wide selection of current probes to meet your applications needs - Data Sheet Hybrid technology for AC and DC measurements Using hybrid technology that includes a Hall-effect sensor and an AC current transformer, the probes provide accurate measurement of DC or AC currents up to 500 Arms (for model N2780B) or DC100 MHz (for model N2783B), without breaking into the circuit. Using split core construction, the probe easily clips on and off of a conductor. Figure 1. N2780B Series current probes with Wide range of applications N2779A power supply The current probes feature broad measurement ranges (up to 500 A), flat frequency response, low noise and low insertion loss that make the probes ideal Various bandwidths: DC to 2 MHz, for current measurements in areas such as measuring steady state or transient 10 MHz, 50 MHz, 100 MHz current of motor drives, switching power supplies, inverters, controllers, sensors, DC and AC measurements disk drives, LCD displays, electronic ballasts and amplifiers. The high signal-to- Superior 1% accuracy and high noise ratio of the N2782B and N2783B makes them ideal for making low-level signal-to-noise ratio current measurements in milliampere ranges. O v e r l o a d - p r o t e c t f un c t i o n prevents probe damage from Accurate current measurement excessive input Direct connection to high- A built-in DEMAG (demagnetize) function allows the removal of any residual impedance 1 M BNC input of magnetism that has built up in the magnetic core due to power on/off switching oscilloscope or excessive input current. In addition, voltage offset or temperature drift on the Demagnetize button to remove probe can be easily corrected by using the zero adjustment control. any residual magnetism that builds up in the magnetic core E xternal power supply (N2779A) lets you connect up to three N278xB current probes to a single power supply Compatible with any oscilloscope with a high-impedance BNC input, the new N2780B Series current probes offer accurate and reliable Figure 2.
