A dual-beam oscilloscope was a type of oscilloscope once used to compare one signal with another. There were two beams produced in a special type of CRT . Unlike an ordinary "dual-trace" oscilloscope (which time-shared a single electron beam, thus losing about 50% of each signal), a dual-beam oscilloscope simultaneously produced two separate ...
At that time, most test instruments, such as the oscilloscope and logic analyzers in design, and in-circuit test (ICT) in volume manufacturing were external to the chips and circuit boards. They relied upon placing a probe on a chip or a circuit board to obtain test data.
A spectrum analyzer from 2005 A modern real time spectrum analyzer from 2019. A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.
A signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the IF bandwidth of the instrument. It employs digital techniques to extract useful information that is carried by an electrical signal. [1] In common usage the term is related to both spectrum analyzers and vector signal ...
A logic analyzer is similar to an oscilloscope, but for each input signal only provides the logic level without the shape of its analog waveform. A mixed-signal oscilloscope (or MSO) meanwhile has two kinds of inputs: a small number of analog channels (typically two or four), and a larger number of logic channels (typically sixteen).
Logic analyzer. A logic analyzer is an electronic instrument that captures and displays multiple logic signals from a digital system or digital circuit. A logic analyzer may convert the captured data into timing diagrams, protocol decodes, state machine traces, opcodes, or may correlate opcodes with source-level software. Logic analyzers have ...
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
For example, new mainframe-based curve tracer systems can be configured by specifying the number and power level of the Source Measure Units (SMUs) to be plugged into the slots in the back panel of the chassis. This modular design also provides the flexibility to incorporate other types of instrumentation to handle a wider range of applications.
