Use the N2790A 100-MHz high-voltage differential probe to make safe and accurate floating measurements with an oscilloscope. The N2790A probe allows conventional earth-grounded Keysight oscilloscopes to be used for floating signal measurements of up to 1,400 V of differential voltage and 1,000 V of common mode voltage.
Thanks to its high bandwidth and excellent input-impedance characteristics, the probe can accurately measure up to 3.5 nsec of fast transient edges in modern switching power supplies.
The probe is compatible with Keysight’s AutoProbe interface with 1 Mohm input where the probe’s power is supplied by the Keysight oscilloscope’s probe interface.
When probing differential signals inside of environmental chambers at extreme temperatures, Keysight offers the N7013A extreme temperature extension kit. The N7014A is compatible with the N2790A with a de-rated bandwidth of 70 MHz. The 70 cm long differential cable set and accessories can operate in temperatures ranging from -40 degrees to +85 degree Celsius.
