The Video Display Clamp
Product Description
The Tektronix 013-0278-00 Video Display Clamp is an active signal processor
designed to increase your ability to monitor video signals.
Figure 1: The video display clamp
Video signals containing a 60 Hz ripple or a DC offset make it difficult to view
the video signal with an oscilloscope. The Video Display Clamp provides a
stable signal to the oscilloscope by clamping the back porch of the video signal
to ground reference. This does not affect the signal source.
Figure 2 gives an example of how a 60 Hz hum disrupts the capability to view
the video signal. Figure 2 also shows the same signal stabilized by using the
Video Display Clamp. You can see how this enhances your ability to take
measurements of the video signal.
