N2790A

N2790A is a 100MHz 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 1,400V of differential voltage and 1,000V of common mode voltage. Due to its high bandwidth and excellent input-impedance characteristics, the probe can accurately measure up to 3.5nsec of fast transient edges in modern switching power supplies. The probe is compatible with Keysight’s AutoProbe interface with 1Mohm input where the probe’s power is supplied by the Keysight oscilloscope’s probe interface.

• Rise time (calculated) is ≤3.5ns
• User-selectable attenuation settings of 50:1 or 500:1
• Rated to measure differential voltage up to 1,400VDC + peak AC with high CMRR of <gt/>50dB at 1MHz
• Overrange indicator which alerts the user when the probe input exceeds dynamic range of the probe
• AutoProbe interface
• Operating temperature range from -10 to 50°C
