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.
