The term discrete comes from the realm of programmable logic controllers (PLCs) used in industrial control systems, and it has an advantage over a more general term such as digital in that it specifically implies a single signal or circuit intended for use as an interface to some external device. Chapter 13 covers analog interface concepts and components. The opposite of discrete is analog, the realm of indefinite variable values. The infrared motion sensor is either active, or it isn’t. The microwave oven is powered on, or it isn’t. This is probably the most common, and useful, type of interface encountered in digital electronics. It also touches on topics such as buffers, logic-level translation, and current sink and sourcing considerations.Ī discrete interface involves a single signal, typically binary in nature. This chapter covers the basics of using a discrete signal on a single logic I/O port to sense and control things in the physical world.

Additionally, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals.Practical Electronics: Components and Techniques (2015) Chapter 12. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data the result is a perfectly matched probe and gauge for enhanced performance. The easy to use keypad on the Surveyor Thickness Gauge allows operator interface whilst the bright LCD display can be used in all light conditions. The gauge can be used for metal, GRP or plastic measurement and it automatically switches modes and settings depending on the type of probe fitted. The user has a choice of Multiple Echo, Echo to Echo or Single Echo to cover all requirements. The Multigauge 5650 Surveyor Thickness Gauge is a simple, robust ultrasonic thickness gauge designed specifically for ship and small craft surveyors, but can also be used in applications where different measurement modes are required.

Included with the SpW-10X Router ASIC Evaluation Kit is a power brick and a full user manual highlighting test points and switches. To ensure authenticity, various input and output signals are not buffered, enabling the user to closely monitor the behaviour of the ASIC. However, inside the unit each signal from the ASIC is brought out to a standard 0.1” pitch header to allow an easy connection to a logic analyser or oscilloscope. With 8 SpaceWire ports on the front, two parallel FIFO ports and a time-code interface on the back much of the evaluation work can be performed without opening the unit. The Evaluation Kit is ready to work “out-the-box” and can save months of development whilst reducing risk and costs. Also known as the AT7910E, the SpW-10X Router ASIC is the most versatile, configurable, and easiest to use radiation tolerant SpaceWire routing device available.
The SpW-10X Router ASIC Evaluation Kit is designed to provide the user with an easy platform to evaluate the SpW10-X Router ASIC from Atmel.
