Accurate Current Measurements
Without Breaking the Circuit
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, making it ideal for
general-purpose, high-frequency
current probing in lab and bench
environments. This probe is the
best choice for measuring steady
state or transient current of
motor drives, switching power
supplies, inverters, controllers,
disk drives, LCD displays, and
current amplifiers driving induc-
tive loads.
The probe’s hybrid technology
includes a Hall Effect device to
sense the dc current and a cur-
rent transformer to sense the ac
current, making an electrical con-
nection to the circuit unneces-
sary. Using split core construc-
tion, the probe easily clips on and
off of a conductor up to 5 mm in
diameter.

A Degauss function allows the
removal of any residual magnet-
ism that has built up in the mag-
netic core due to power on/off
switching or excessive input. In
addition, voltage offset or temper-
ature drift on the probe can be
easily corrected by using the zero
adjustment dial.

The 1147A is compatible with the
AutoProbe interface, which com-
pletely configures the oscillo-
scope for the probe. Probe power
is provided by the scope, so there
is no need for an external amplifi-
er or power supply. A snap-on
BNC connector simplifies con-
necting the probe to the scope.
