Keysight N2790A High-Voltage Differential Probe

Keysight N2790A High-Voltage Differential Probe – 100 MHz

In today’s power electronics and measurement applications, analyzing high-voltage floating and differential signals requires tools that ensure both safety and accuracy. The Keysight N2790A is purpose-built to meet these demands, making it a trusted choice for engineers in R&D labs, industrial environments, and production testing.

Key Features:

• Wide measurement range: Supports up to 1,400 VDC + peak AC differential and 1,000 V common mode voltage.

• Selectable attenuation: 50:1 or 500:1 for flexible measurement across voltage levels.

• Excellent noise rejection: With CMRR >50 dB at 1 MHz, the probe delivers accurate results even in noisy environments.

• Safety overrange indicator: Alerts users when input signals exceed the probe’s dynamic range.

• 100 MHz bandwidth: Captures fast transients with rise times as low as 3.5 ns, ideal for switching power supply analysis and high-power circuits.

Included Accessories:

• Two browser tips

• Two retractable hook tips

• Two alligator clips

Broad Compatibility:

• Keysight InfiniiVision 3000 X-Series, 4000 X-Series

• InfiniiVision 5000, 6000 (except 100 MHz), 7000 Series (fw ≥5.26.0001)

• Keysight Infiniium S/V/Z/90000 X/90000 Q Series (with N5449A adapter)

• Infiniium 8000, 54830 (fw ≥5.7), Keysight 9000 (fw ≥2.0)

With 100 MHz bandwidth and excellent input impedance, the probe accurately measures fast transients with rise times up to 3.5 ns, making it ideal for modern switching power supplies.

For extreme environments, the N7013A/N7014A extension kits allow operation from –40 °C to +85 °C (70 MHz bandwidth).
