Overview
Description
The AP033 is a wide band differential active probe. The probe features low noise, low input
capacitance, high common mode rejection, and FET-buffered inputs in the probe head. User
selectable attenuation and offset give the probe flexibility to measure a large range of signal
amplitudes. Plug-on attenuator and AC coupling accessories further extend the application range.
Interconnect accessories included allow connection to surface mount and through-hole
components with minimal signal degradation. The input receptacles in the probe head are
compatible with standard 0.025 in. (0.635 mm) square pins. This provides a convenient low cost
method of creating device characterization test fixtures.
The probe is powered directly from a Teledyne LeCroy oscilloscope through the ProBus® interface.
The ProBus interface also allows local control of the probe through the oscilloscope user interface
and remote control through the interface buses, (GPIB, RS-232). The optional ADPPS power supply
allows the AP033 to be used with other instruments such as spectrum analyzers, network
analyzers, and oscilloscopes without ProBus interface.
Applications
The AP033 is ideal for acquiring high speed differential signals such as those found in disk drive
read channels, differential LAN, video, etc. It can also be used with spectrum analyzers to acquire
signals in some RF systems (for example, balanced IF mixers in hand held cellular telephones). The
high impedance characteristics of both inputs allow the probe to be used as a FET probe to make
single-ended measurements in digital systems without introducing a ground loop, as a conventional
FET probe would.
