Modular Oscilloscopes vs. Digitizers

Modular instruments are a powerful option in the test equipment designer's tool kit -- especially in automatic test equipment (ATE) applications that require high channel density and digital programmability. They provide all of the needed test functions, without the added expense and size of benchtop instruments. Modular digitizers are often used in the front end of modular instruments, since analog signals need to be converted into digital form for analysis and processing. ATE designers are often challenged when using modular digitizers, because digitizers are not as capable as benchtop oscilloscopes -- particularly when it comes to breadth of measurement features and functions.
