This is called a "dual trace" oscilloscope. The switch worked to display 2 or 4 separate electrical signals on the screen. This required little duplication and added only a small amount to the cost. This is the technique used in all the dual and four-trace plug-ins such as the CA, 1A1, 1A2, Type M and 1A4.
It can be an external input, one of the vertical channels of a dual or multiple-trace oscilloscope, or the AC line (mains) frequency. Another switch enables or disables auto trigger mode, or selects single sweep, if provided in the oscilloscope. Either a spring-return switch position or a pushbutton arms single sweeps.
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 ...
BC-403-C oscilloscope. A key innovation in the SCR-270 was a transmit-receive (TR) switch. The SCR-268 searchlight control radar, which shared much technology with the SCR-270, used separate antennas for transmit and receive, For maximum antenna gain at a given size it is desirable to use the same antenna for both functions. One obstacle is the ...
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.
A Tektronix TDS210 digital oscilloscope. A digital storage oscilloscope (DSO) is an oscilloscope which stores and analyses the input signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides. [1]
The BK Precision model 4078 Dual Channel Arbitrary Waveform Generator uses direct digital synthesis to generate waveforms up to 400,000 points HAMEG HMF 2550 digital AWG under an oscilloscope displaying the generated waveform. An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.
This so-called I–V (current versus voltage) data is either directly displayed on an oscilloscope screen, or recorded to a data file for later processing and graphing with a computer. [1] Configuration includes the maximum voltage applied, the polarity of the voltage applied (including the automatic application of both positive and negative ...
