Probing LVDS Signals
LVDS signals are high speed, low swing signals. Improper probing can result in
deceiving results since the probe and/or scope can filter high speed components of
the signal. Using a >1 GHz bandwidth scope (such as the Agilent 86100 or Tektronix
694C) and a high speed differential probe (such as the Tektronix P6247/8 or P6330) is
highly recommended. LVDS drivers are not compatible with 50-Ohm probes.
