LeCroy AP011 Current Probe
The Probe is in excellent condition.
The AP011 allows the
oscilloscope to measure current flowing through a conductor. The AP011 is
based on a combination of Hall effect and transformer technology which
allows measurements to be made on DC, AC and impulse currents. It is rugged
in design and uses a split-core transformer to allow the probe head to be
clamped around a conductor that remains in circuit.
ProBus interface, the AP011 probe becomes an integral part of the
oscilloscope. The probe is automatically detected with full calibration and
control achieved from the on-screen menu system. No external power supplies
or amplifiers are required.
control is possible over GPIB or RS-232-C interfaces.
scaling factors and unit conversions are automatically applied.
wide range of oscilloscope software analysis functions and parameter
measurements is compatible and handles mixed-unit conversion.
compatibility ensures full integration of the AP011 features into the
oscilloscope. The probe is fully operational whenever it is attached to the
instrument. There is no need for external amplifiers or power supplies. All
controls are menu-driven from the oscilloscope screen, avoiding the need for
accessing probe-mounted controls which can be particularly difficult and
dangerous in some applications.
calibration of the probe is achieved by using the auto-zero feature. This
should be done whenever the probe is first connected, subjected to wide
temperature variations, re-oriented with respect to the earth's magnetic
field, or subjected to overload conditions. The auto-zero operation on the
AP011 is performed automatically by pressing the 'AUTO ZERO' menu button in
the associated channel menu.
Measurement Unit Conversion
conversion and calibration ensure correct interpretation of data and avoid
the painstaking task of recording and applying conversion and scaling
acquired from the AP011 are automatically calibrated and adjusted to be
scaled in ampere units. A wide range of functions can be applied to current
waveforms. Advanced functions such as FFTs and statistical analysis are
available as optional firmware packages.
and measurements recognize ampere vertical scales and adjust the resulting
waveform or calculation units, including mixed unit conversions.
