Keysight N2790A Differential Voltage ProbeUser GuideIntroductionThe N2790A differential probe allows you to safely measure high-voltagefloating circuits with the oscilloscope grounded. It is ideal for manyapplications such as motor speed controls, power supply designs, andelectronic high-power converters. The N2790A offers sufficient dynamicrange and bandwidth for your application to make the floatingmeasurements found in high-speed power electronic circuits safely andaccurately.With 100 MHz bandwidth, switchable attenuation of 50:1 and 500:1, and amaximum differential voltage input of 1400V (DC + peak AC), it providesthe versatility for a broad range of applications including high-voltagecircuits. The probe is powered by the auto-probe interface.CompatibilityThe N2790A differential probe is compatible with the following Keysightoscilloscopes:• InfiniiVision Series 5000, 6000 (except 100 MHz), and 7000 with version5.2 software or later• Infiniium 9000 (with version 2.00 software or later), 8000 (with version5.61 software or later), and 54830 Series (with version 5.61 software orlater)Inspecting the Probe• Inspect the shipping container for damage.Keep the damaged shipping container or cushioning material until thecontents of the shipment have been checked for completeness and theprobe has been checked mechanically and electrically.• Check the accessories.If the contents are incomplete or damaged, notify your KeysightTechnologies Sales Office.• Inspect the instrument.If there is mechanical damage or defect, or if the probe does notoperate properly or pass calibration tests, notify your KeysightTechnologies Sales Office.
