A vectorscope is a special type of oscilloscope used in both audio and video applications. [1] Whereas an oscilloscope or waveform monitor normally displays a plot of signal vs. time, a vectorscope displays an X-Y plot of two signals, which can reveal details about the relationship between these two signals.
ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...
A vector signal analyzer operates by first down-converting the signal spectra by using superheterodyne techniques. A portion of the input signal spectrum is down-converted [ broken anchor ] (using a voltage-controlled oscillator and a mixer ) to the center frequency of a band-pass filter .
The display of a spectrum analyzer has frequency displayed on the horizontal axis and the amplitude on the vertical axis. To the casual observer, a spectrum analyzer looks like an oscilloscope, which plots amplitude on the vertical axis but time on the horizontal axis. In fact, some lab instruments can function either as an oscilloscope or a ...
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 vector monitor, vector display, or calligraphic display is a display device used for computer graphics up through the 1970s. It is a type of CRT , similar to that of an early oscilloscope . In a vector display, the image is composed of drawn lines rather than a grid of glowing pixels as in raster graphics .
A Tektronix model 475A portable analog oscilloscope, a typical instrument of the late 1970s Oscilloscope cathode-ray tube, the left square-shaped end would be the blue screen in the upper device when built in. Typical display of an analog oscilloscope measuring a sine wave signal with 10 kHz. From the grid inherent to the screen together with ...
The separate PC provides the display, control interface, disc storage, networking and often the electrical power for the acquisition hardware. The external oscilloscope can transfer data to the computer in two main ways – streaming and block mode. In streaming mode the data is transferred to the PC in a continuous flow without any loss of data.
