Current Probes

Up to 100 MHz bandwidth and

500 Arms current

Hybrid technology to measure

ac and dc

Compatible with any 1 MΩ

scope input

Accurate current

measurements without

breaking the circuit

Compatible with any scope or voltage

measuring instruments with BNC

input, the 1146A and N2780A Series

current probes offer accurate and

reliable solutions for measuring dc

and ac currents. The probes use a

hybrid technology that includes a

Hall effect sensor, which senses the

dc current and a current transformer,

which senses the ac current, making

it unnecessary to make an electrical

connection to the circuit.

1146A 100 kHz current probe

The 1146A ac/dc current probe

provides accurate display and

measurement of currents from

100 mA to 100 Arms, dc to 100-kHz,

without breaking into the circuit. A

battery level indicator and overload

indicator help ensure proper readings.

It connects directly to the scope

through a 2 m coaxial cable with an

insulated BNC.

N2780A Series current probes with N2779A power supply

1147A 50-MHz current probe

with AutoProbe interface

The 1147A is a wide bandwidth,

dc to 50-MHz current probe. The

probe offers flat frequency response

across the entire dc to 50-MHz

bandwidth, low noise (< –2.5-mArms)

and low circuit insertion loss.

The 1147A probe is compatible

with the AutoProbe interface,

which completely configures the

oscilloscope for the probe when

used with the 5000/7000 Series and

300-MHz - 1-GHz 6000 Series scope.

Probe power is provided by the scope,

so there is no need for an external

power supply.

N2780A/81A/82A/83A

2-MHz/10-MHz/50-MHz/

100-MHz current probe

The N2780A Series current probes

are high bandwidth, active current

probes, featuring flat bandwidth, low

noise (< –2.5-mArms) and low circuit

insertion loss. In conjunction with

the power supply (model N2779A),

this probe can be used with any

oscilloscope having a high-impedance

BNC input. The companion power

supply N2779A (3x 12 Vdc output)

lets you connect three N2779As to a

single power supply.
