Selecting the Channels (PSO-102 Only)
You can view either channel A, B, or both in either the top or bottom
window. You can also set your Optical Sampling Oscilloscope to
automatically detect which channel is active and display it accordingly.
To select the channel to display:
1. From the main window, select the Setup menu, then View.
2. Select which channel configuration you want to view.
You can also display a balanced signal, A-B or B-A. It is almost
mandatory in DPSK and DQPSK receivers to perform balanced
detection. Here we can do the balanced detection in software and
visualize a balanced detected eye diagram with very high bandwidth.
