For example, the Tektronix 7D11 Digital Delay uses a counter architecture. [25] A digital delay may be set from 100 ns to 1 s in 100 ns increments. An analog circuit provides an additional fine delay of 0 to 100 ns. A 5 MHz reference clock drives a phase-locked loop to produce a stable 500 MHz clock. It is this fast clock that is gated by the ...
The 7D11 ($2,915 in 1983) was a digital delay, the 7D15 ($3,020) was a 225 MHz counter/timer, the 7D13 ($1,105) was a multimeter, and the 7D12/M2 ($2,815) was a sample-and-hold with an analog-to-digital converter. More exotic digital plug ins used the mainframe oscilloscope as a mere display unit. The 7D01 and 7D02 were logic analyzer plug ins.
Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing.
In the case of digital oscilloscopes, an analog-to-digital converter (ADC) changes the measured voltages into digital information. The digital storage oscilloscope, or DSO for short, is the standard type of oscilloscope today for the majority of industrial applications, and thanks to the low costs of entry-level oscilloscopes even for hobbyists.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
4-channel stereo multiplexed analog-to-digital converter WM8775SEDS made by Wolfson Microelectronics placed on an X-Fi Fatal1ty Pro sound card AD570 8-bit successive-approximation analog-to-digital converter AD570/AD571 silicon die INTERSIL ICL7107. 3.5 digit (i.e. conversion from analog to a numeric range of 0 to 1999 vs. 3 digit range of 0 to 999, typically used in meters, counters, etc ...
WYPX-TV requested permission from the FCC to shut down their analog signal on channel 55 so that the bandwidth could be used for Qualcomm's MediaFLO service. Qualcomm had made deals with other stations on channel 55, including WLNY-TV in Riverhead, New York , to shut down analog so that they could launch their new multimedia offering on April ...
The time-stretch analog-to-digital converter (TS-ADC), [1] [2] [3] also known as the time-stretch enhanced recorder (TiSER), is an analog-to-digital converter (ADC) system that has the capability of digitizing very high bandwidth signals that cannot be captured by conventional electronic ADCs. [4]
