N2790A Keysight

N2790A 100 MHz, N2791A 25 MHz and N2891A 70 MHz High-Voltage Differential Probes Introduction Oscilloscope users often need to make floating measurements where neither point of the measurement is at earth ground. Use the N2790A, N2791A or N2891A high-voltage differential probe to make safe and accurate floating measurements with an oscilloscope. The N2790A, N2791A and N2891A high- voltage differential probes allow conventional earth-grounded Keysight Technologies, Inc. oscilloscopes to be used for floating signal measurements. Find us at www.keysight.com Page 1 With a differential amplifier in the probe head, the N2790A is rated to measure differential voltage up to 1,400 VDC + peak AC with high CMRR (common mode rejection ratio) of > 50 dB at 1 MHz. The N2791A and N2891A can measure differential voltage up to 700 V and 7 kV differential or common mode respectively. The N2790A, N2791A and N2891A differential probe offers sufficient dynamic range and bandwidth for your application to make the floating measurements found in power electronics circuits safely and accurately. The N2790A, N2791A and N2891A differential probe offers user selectable attenuation settings that make it highly versatile, allowing it to be used for a broad range of applications. The probe comes with probe tip accessories for use with both small or large components in tight places. The N2790A and N2891A also have an overrange indicator which alerts the user when the probe input exceeds the dynamic range of the probe. The N2791A and N2891A are compatible with any oscilloscope with 1 Mohm BNC input. The N2791A and N2891A probes power is supplied by included 4x AA batteries or USB host port of the scope or PC via a supplied USB power cable. The N2790A is compatible with the Keysight Technologies, Inc. AutoProbe interface where the probes power is supplied by the Keysight oscilloscopes probe interface. Figure 1.
