1147A 50 MHz Current Probe
Introduction
The 1147A is a wide- band, DC to 50 MHz, active current probe.
The probe features low noise and low circuit insertion loss. The
intelligent interface makes the probe ideal for use with the
InfiniiVision and Infiniium products using the AutoProbe interface.
This unique probe interface makes current measurements as
simple as those made with the active voltage probes.
The 1147A has two operating regions that provide a wide, flat
frequency response. In the DC to low frequency AC region, the
probe operation is based on the negative feedback of the amplifier
system that includes the thin film Hall element as a detector. In
the high frequency region, the probe operates as a current
transformer.
The 1147A is ideal for acquiring high transient time signals such
as those found in Motor Controllers, in Switching Power Supplies,
and in Current Amplifiers driving inductive loads.
In order to use this product effectively and to ensure a long
operational life, read this User's Guide carefully and retain it for
future reference.
