AP015 Data Sheet
Fully Integrated System
ProBus compatibility ensures full integration of the AP015 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. Full Remote control is possible over GPIB or
RS-232-C interfaces.
Auto-Zero Adjustment
Optimal 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, or subjected to overload conditions. The auto-zero
operation on the AP015 is performed automatically by pressing the "AUTO
ZERO" menu button in the associated channel menu (see Figure 1).
Automatic Measurement Unit Conversion
Automatic unit conversion and calibration ensures correct interpretation of data
and avoids the painstaking task of recording and applying conversion and
scaling factors.
All waveforms acquired from the AP015 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 FFT and
statistical analysis are available as optional firmware packages.
All functions
and measurements recognize ampere vertical scales and adjust the resulting
waveform or calculation units, including mixed unit conversions.
Degauss Function
Optimal use of a current probe implies the utilization of a backing current to
eliminate core saturation by applying an alternating field that is reduced in
amplitude over time from an initial high value (i.e., AC powered). This function is
automatically performed by pressing the "DEGAUSS" menu button in the
associated channel menu (see Figure 1)

measured with the AP015.
Overheating Detection
The AP015 is equipped with an automatic overheating detection circuit which
generates a warning message displayed on the oscilloscope screen to avoid
damaging the probe.
Probe Unlock Detection
This avoid carrying out wrong measurements, with the probe head ground
connection badly locked. The probe send to the scope an interrupt and displays
a warning message on the oscilloscope screen at any time, if the probe head is
not well closed.
