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
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.
