The following sections describe the controls on the SDI HSMC - Video tab.

Pattern Generator

The SDI HSMC has two transmitter channels (CH1 Tx and CH2 Tx) and two receiver

channels (CH1 Rx and CH2 Rx). When a receiver channel has valid video input, the

corresponding transmitter channel transmits the input video stream. When no valid

video input is present, the each transmitter outputs a video pattern based on the

following settings:

■ Pattern—Specifies the test pattern to output to the monitor. The following choices

are available:

■ Color bar—Specifies a video color bar pattern with eight vertical color bars.

(Refer to Table 6–2)

■ Pathological—Specifies a video color bar pattern with two horizontal color

bars that stresses the receive PLL.
