N2790A/91A and N2891A high
voltage differential probes
Oscilloscope users often need to
make floating measurements where
neither point of the measurement
is at earth ground. Use N2790A,
N2791A, or N2891A high voltage
differential probes to make safe and
accurate floating measurements
with an oscilloscope. The N2790A,
N2791A, and N2891A high voltage
differential probes allow conventional
earth-grounded Agilent oscilloscope
to be used for floating signal
measurements.
Each 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 small and
large components in tight spaces.
The N2791A and N2891A are
compatible with any oscilloscope
with 1 MΩ BNC input. The N2791A
and N2891A probe 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
Agilent’s AutoProbe interface where
the probe power is supplied by the
Agilent oscilloscope’s probe interface.

1141A 200 MHz differential
probe
The 1141A is a 1x FET differential
probe with 200-MHz bandwidth and
a 3000:1 CMRR. The probe has a
high-input resistance and low-input
capacitance of 7 pF to minimize
circuit loading. The 1141A must be
used with 1142A probe control and
power module, which controls input
coupling modes dc, dc with variable
offset, and dc reject. Two attenuators,
10x and 100x are provided to expand
the linear differential input range to
±30 V. This probe works with any
50-Ω input oscilloscope including
3000 X, 5000, 6000 300 MHz - 1 GHz,
and 7000 Series.
