In this, the electronic switch alternates between channels A and B, letting each through for one cycle of the horizontal sweep. There are two common operating modes for the electronic switch, called alternate and chop and these are selected from the instrument's front panel. After pre-amplification the two channels meet at an electronic switch, this has the ability to pass one channel at a time into the vertical amplifier, via the delay line. ![]() Therefore the amplitude of each input, as viewed on the oscilloscope, can be individually controlled. There are two separate vertical input channels A, B and these use separate attenuator and preamplifier stages. ![]() ![]() How do you differentiate between dual beam and dual trace oscilloscope?
