Computer model of the impact of increasing the timebase time/division. These select the horizontal speed of the CRT's spot as it creates the trace; this process is commonly referred to as the sweep. In all but the least-costly modern oscilloscopes, the sweep speed is selectable and calibrated in units of time per major graticule division.
The time per division on the display depended upon the sweep's free-running frequency and a horizontal gain control. A synchronized sweep oscilloscope could not display a non-periodic signal because it could not synchronize the sweep generator to that signal. Horizontal circuits were often AC-coupled
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.
A real-time oscilloscope, which also used to be called a “single-shot” scope, captures an entire waveform on each trigger event. This requires the scope to capture a large number of data points in one continuous record. A sequential equivalent-time sampling oscilloscope, sometimes simply called a “sampling scope,” measures the input ...
A time base generator (also timebase or time base) is a special type of function generator, an electronic circuit that generates a varying voltage to produce a particular waveform. Time base generators produce very high frequency sawtooth waves specifically designed to deflect the beam of a cathode ray tube (CRT) smoothly across the face of the ...
The series also included some storage scopes: 7613 (variable persistence, $5,025 in 1983), 7623, 7633 (100-MHz BW, $7,765), and 7834 (400-MHz BW, $11,705). The series also wandered into digital oscilloscope territory. The 7854 waveform processing oscilloscope ($13,750 in 1983) could function as both an analog or a digital oscilloscope with GPIB ...
Allen DuMont became Group General Manager of the DuMont Division, until his death in 1965. [2] All DuMont oscilloscopes in the late 1950s and after the Fairchild acquisition were using the time base trigger and time sweep generator method introduced by Tektronix. The DuMont line of oscilloscopes continued to be produced into the 1980s. [13]
The smallest meaningful increment of time is the Planck time―the time light takes to traverse the Planck distance, many decimal orders of magnitude smaller than a second. [ 1 ] The largest realized amount of time, based on known scientific data, is the age of the universe , about 13.8 billion years—the time since the Big Bang as measured in ...
