03 | Keysight | N2790A 100 MHz, N2791A 25 MHz and N2891A 70 MHz High-voltage Differential Probes - Data Sheet
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 probe’s
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 probe’s power is supplied by the Keysight
oscilloscope’s probe interface.
