Active Differential Probes

20 MHz to 1.5 GHz bandwidth

Switchable attenuation

Measure up to 600 V CAT III and

1000 V CAT II

N2772A 20 MHz differential

probe

Use the Agilent N2772A differential

probe with any of the 5000, 6000,

or 7000 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 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 5000 and

6000 Series.
