You can connect for example the output of a sine wave generator to both CH1 and CH2 input jacks of the oscilloscope and see both traces simultaneously on the screen of the CRO over a wide range of settings of Time per division of the scope.
Vertical mode and normal trigger of the scope are set at dual and CH1.
However, when I connect the output of a tone burst generator to both CH1 and CH2 input jacks of the CRO, if Time/ Div. is set at less than 1 millisecond, then what happens is firstly only the CH1 trace appears on the screen, then secondly only the CH2 trace appears on the screen, and then a repeat of one and then the other trace separately on the screen.
The burst generator is (Siegfried) Linkwitz's cosine burst generator, which is ten half-waves in a burst at whatever audio frequency a sine wave generator at input to the burst generator is set.
It would be more convenient if both traces would appear simultaneously on the screen as I want to use the scope to measure any time delay effected by circuitry inserted between the burst generator and the CH2 input of the scope.
Time/ Div set at less than 1 millisecond is better as I anticipate a delay of about 0.5 ms and possibly less.
The two traces not appearing simultaneously on the screen would be acceptable if both traces start at exactly the same position on the screen. But even so, I am curious as to why the "split" occurs when Time/ Div. is made less than 1 ms.
Thanks for your help with this puzzle where possible,
