in the dual trace cro the same electron beam is used to generate the two traces that can be deflected from two independent vertical source
The signal trace capability of the conventional CRT can be modified to produce dual image or dual trace display, by means of fast electronic switching of two separate input signals. Channel A and Channel B with preamplifier and delay lines feed their input to an electronic switch that alternately connects the input of the main vertical amplifier to the two signal inputs. The same are displayed with various display modes.
When the display mode selector is in the alternate position, the electronic switch alternately connects vertical amplifier to channel A & B. The switching rate is synchronized to the sweep rate, so that CRT spot traces channel A signal on one sweep and channel B on next. Since these signals have calibrated input attenuator and a vertical position control, the amplitudes of the input signal can be adjusted individually and the two images placed separately on the screen. This mode is useful with fast sweep rates, when the two images appear as one simultaneous and state display.
In chopped mode electronic switch is free running at the rate of 100 to 500 kHz, entirely independent of the frequency of the sweep generator. In this, switch successively connects small segments of A and B waveforms to the main amplifier. At fast chopping rate of 500 kHz, or say 1 microsecond, sweep of each waveform is fed to CRT for display. If the chopping rate is much faster than the sweep rate, the individual segments reconstitute the original A and B waveforms on screen without interruptions in the two images. If sweep rate approaches the chopping rate, the segments' waveforms become visible as individual images and the continuity of image display is lost, which is less picturesque than the alternate mode of position.
The use of polarity inversion switches can display A+B, A-B, B-A, and -A-B modes.
In the X-Y mode the sweep generator disconnects channel B and is connected to the horizontal amplifier. This gives good X-Y measurements with same amplifications. In addition the dual trace CRO can be used as single beam CRO, displaying either A or B as a function of time.
What else can I help you with?
Can you measure current with an oscilloscope?
Oscilloscopes only measure voltage over time. Current cannot be measured with an Oscilloscope directly, but can be measured indirectly. Measure the voltage across a known load and calculate the current.
Why does one trace of the oscilloscope traces have to be inverted to display the voltage and current with the correct phase relationship?
One trace of the oscilloscope traces have to be inverted to display the voltage and current with the correct phase relationship because you are probably connecting to both sides of a small resistor in series with the load. The supply side shows voltage, while the load side shows voltage drop for the load. You are showing differential voltage across the resistor in the second trace and, of course, its negative.If, however, you are using a current probe, perhaps a clamp-on ammeter, I would question if you have it connected correctly.
How do you troubleshoot generator that fails to supply ac voltage?
You first use the schematic diagram in the equipment service manual to understand the flow of the power and signals in the generator. The first thing to check is all of the power supply voltages. If one is missing, the generator can fail in such a way as to produce no output. Then you can use an oscilloscope to trace the problem backwards, from the output connector of the generator to to the source of the signal generation.
How does the anode voltage applied to the cathode ray oscilloscope affects the sensitivity of the CRO?
The anode voltage does not affect the sensitivity of a CRO. The input amplifier and deflection circuit have a greater influence. The Anode voltage will affect the focus and visibility of the trace, in this respect it will affect how you see the result.
Does the bulb light up in a parallel circuit?
The bulb will shine as long as it is still part of a complete circuit. You probably have a diagram for such a circuit. See if you can still trace a path through the battery and one of the bulbs without passing through the other bulb. For comparison, try the same thing with a diagram of a series circuit.
What are the advantages of dual trace over dual beam CRO for multiple trace?
what are the advantages of dual trace oscilloscope
Is the oscilloscope trace movement across the CRT related to time?
Yes
What oscilloscope control moves the trace up and down the screen vertically?
position
Will a dual trace oscilloscope have one set of position control?
Nope - it has controls for each trace. I have a DTO and it has controls to position the trace horizontally for each channel.
Oscilloscope trace of high pitched loud note?
high frequency, high amplitude.
Price of dual trace oscilloscope tektronix 465b?
About $100-$300 depending on condition!
What is the frequency of an oscilloscope trace?
In order to find the frequency of an oscilloscope trace, you must first find the period, which is the time it takes for one oscillation, which can be found by measuring the amount of time from one peak our trough to the next. The frequency is the number of oscillations per second, and can be found by dividing 1 by the period in seconds.
What is the difference between dual trace cro and dual beam cro?
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 is Difference between dual trace oscillosope and dual trace generator?
Oscilloscope is used to display electrical signals on a display. A dual trace oscilloscope can display two signals simultaneously. For a trace generator I think you mean a signal or a function generator which generates electrical waveforms of varying shapes, frequency and amplitude. A dual trace or a function generator in that sense is an equipment capable of generating two independent waveforms at the same time. - Neeraj
Working principle 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.
Which oscilloscope control is used to move the trace up and down the screen vertically?
More than likely, it is the DC Offset.
What does an oscilloscop do?
An oscilloscope takes an electrical input signal and converts it into a visible trace on a screen - ie it converts electricity into light.
