AC/DC Current Probes - 1147A/N2893A AC/DC Current Probes

The 1147A/N2893A is a wide bandwidth,

dc to 50-MHz/100-MHz current probe.

The probe offers a flat frequency response

across the entire dc to 50-MHz/100-MHz

bandwidth, low noise (< -2.5 mArms), and

low circuit insertion loss.

The 1147A/N2893A probe is compatible

with the AutoProbe interface, which com-

pletely configures the oscilloscope for the

probe when used with the Infiniium 9000

Series scope (1 MΩ input). Probe power is

provided by the scope, so there is no need

for an external power supply. The N2893A

uniquely provides an auto demagnetization

and offset elimination feature when used

in conjunction with Infiniium scope. The

1147A and N2893A are not compatible

with Infiniium 80000 and 90000 Series

oscilloscope.
