Current Probes

• Choice of dc-100 kHz and

dc-50 MHz bandwidth

• 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

N2774A offer accurate and reli-

able 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.

N2775A power supply

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 indica-

tor and overload indicator help

ensure proper readings. It con-

nects directly to the scope

through a 2 m coaxial cable with

an insulated BNC.

N2774A 50 MHz Current Probe

The N2774A is a high bandwidth,

active current probe, featuring

flat bandwidth (dc-50 MHz), low

noise (<2.5 mArms) and low cir-

cuit insertion loss. In conjunction

with the power supply (model

N2775A), this probe can be used

with any oscilloscope having a

BNC input. The companion power

supply N2775A (2x 12 Vdc

output) lets you connect two

N2774As to a single power supply.

AutoProbe interface

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

300 MHz - 1 GHz 6000 Series

scope. Probe power is provided by

the scope, so there is no need for

an external power supply.
