High precision acquisition modules offer 24-bit resolution

The SAM40 provides up to 24 input channels for low frequency (sensor signal) acquisition and analysis. It connects to a 4- or 8- channel Teledyne LeCroy 12-bit resolution high definition oscilloscope (HD4096 HDOs and MDAs) to provide Analogue+Digital+Sensor (up to 8+16+24 channel) acquisitions.

This capability is ideal for system debug and analysis of deeply embedded, electromechanical, and mechatronic designs in the medical, mil/aero, motors and drives, power, appliance, Internet of Things (IoT), vehicle/automotive and other applications.

All channels have 24-bit resolution (stored in 32-bit floating point format) with ~0.05% total accuracy. Built-in filters with settings as low as 100Hz further reduce noise. Adjustable gain ranges (1mV to 10V/div) accurately acquire a wide range of signal levels.

The SAM40 connects to the supported Teledyne LeCroy oscilloscope with a USB2.0 cable for data transfer and control/trigger commands, and BNC cables for clock/timebase synchronisation.

No programming or complex setups are required.

More than 65 different SI and English system physical units are supported for length, mass, temperature, angle, velocity, acceleration, volume, force/ weight, pressure, electrical, magnetic, energy and rotating machine quantities. Math and measurements applied to rescaled waveforms correctly read and convert to new units as required.

The oscilloscope math, measure, analysis, pass/fail and option packages utilize the sensor inputs the same as any other channel.

The SAM40 sensor acquisition module simply and quickly interfaces to a supported Teledyne LeCroy 12-bit high definition oscilloscope (HDO). It acquires very low speed (40kHz bandwidth) sensor and other signals and the HDO acquires higher speed analog, digital and serial data signals.

The HDO cross-triggers the SAM40, and the SAM40 sends acquisition data to the HDO for time-synchronized display with the high bandwidth HDO analog and digital channels.

Engineers commonly use multiple instruments to debug and validate complex deeply embedded control systems, mechatronics, and electro-mechanical systems.

Multiple instruments report different information on different displays and in different formats.

An HDO with a sensor acquisition module cost-effectively replaces multiple instruments with one consolidated view of system performance. The Teledyne LeCroy deep toolbox can be leveraged to perform math, measurements, pass/fail and other analysis on all acquired data, or apply an application package to gain even faster time to insight.

The most basic system available combines a 350 MHz, 500 MHz, or 1 GHz 12-bit resolution, 4 channel oscilloscope (HDO4000A or HDO6000A Series) with a SAM40-8 eight channel acquisition module.

This triples the number of available inputs for a very modest price, and preserves high bandwidth oscilloscope inputs for the most important uses, or provides capability to view more high bandwidth signals than would have previously been possible without the SAM40.

16- and 24-channel acquisition modules may also be used. MSO oscilloscope models further add 16 digital logic input channels.
