hello!
dual beam oscilloscope has 2 filament in crt tube that made 2 independ beam.
but tahe dual trace oscope has 1 beam and made 2 channel indicate on screen by high frquency switcher. it mean,one beam alterative swtch between ch1 and ch2 to indicate 2 channel waveform.
excuse me for bad english knowledge!!
bye
The dual-beam analog oscilloscope can display two signal simultaneously, that is dual beam CRT generator and deflects two separate beams.
In a dual beam oscilloscope we are using two separate electron beam for producing different wave forms. But in a dual trace oscilloscope the same beam is used for producing two different wave forms
what are the advantages of dual trace oscilloscope
Dual-trace operation allows you to view two independent signal sources as a dual display on a single CRT. This operation allows an accurate means of making amplitude, phase, time displacement, or frequency comparisons and measurements between two signals. A dual-trace oscilloscope should not be confused with a dual-beam oscilloscope. Dual-beam oscilloscopes produce two separate electron beams on a single scope, which can be individually or jointly controlled. Dual-trace refers to a single beam in a CRT that is shared by two channels.
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
This is the internal circuit that causes the horizontal movement of the electron beam across the screen of the oscilloscope. It can be adjusted to vary the time taken for the beam to move across the screen.
to get high acceleration for the beam.
A beam will be placed horizontally, a column will be placed vertically.
A beam will be placed horizontally, a column will be placed vertically.
so that there is no higher deflection on the screen
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
An inverted beam is a beam whose bottom is the same as the slab. A drop beam is a beam that is put under the structural member it supports.
Beam can take transvesr loading and bar only axial loading
