I am measuring a communications bus with an oscilloscope at various points along the line. I understand that there will be reflections at each stub as well as at the ends of the bus if the impedance doesn't match. I also understand that these reflected signals will add/subtract with the incident signal as well as change its phase. If I am interested in observing the resultant wave, does it matter where my oscilloscope is located in relation to the transmitter or ends of the lines? For example, if I measure a 150-foot bus at 3 locations: 1) Immediately next to the transmitter at one extreme end of the bus 2) In the middle of the bus (at the 75 foot location) 3) At the extreme end of the bus opposite the transmitter Will the waveforms look the same? The symbol rate is 1 MHz. Thanks for any help.
