Agilent 1141A Data Sheet

5

Differential Probes

• 20 MHz to 200 MHz bandwidth

• Switchable attenuation

• Measure up to 600 V CAT III and
1000 V CAT II

Versatile probing for
your differential signals

Use the Agilent N2772A
Differential Probe with any of
the 54600-Series oscilloscopes to
safely measure floating circuits
with the oscilloscope grounded.
With 20 MHz bandwidth and
switchable attenuation of 20:1
and 200:1, it provides the versatil­ity for a broad range of applica­tions including high-voltage
circuits, motor speed controls,
power supply design, and elec­tronic high-power converters.

Each probe comes with 2 sharp
probe tips for use on small
components and in tight places,
2 retractable probe hooks for
connecting to smaller wires and
through-hole components, and
2 alligator clips for use with
larger cables.

This probe requires a 9 V battery
or Agilent N2773A power supply.

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 ±30V. This probe
works with any 50 Ω input oscil­loscope including 54640-Series.
