the signal, it makes it nearly impossible to obtain a viewable display of the video
information.
Use the Video Display Clamp to reduce or eliminate this type of interference to
view the video signal.
Viewing the video signals can be accomplished with several methods.
H
Connect a video signal directly to the video display clamp (see Figure 3).
H
Tap into a video signal line with a T-connector to monitor the signal without
causing loading interference to the signal (see Figure 4).
H
Connect a 1X probe directly to the video display clamp to probe video
circuits (see Figure 5). The bandwidth of the video display clamp may be
compromised due to the probes characteristics.
