SDI Signal Input
Figure 4-3 SDI input connectors
Apply the signals that are specified in section 2.3.1, “Video Signal Formats and Standards,”
to INPUT SDI A or B. Press the SDI A/B key to switch the measurement channel.
By factory default, the input format is detected automatically, but you can also set it
manually.
Reference 5.1, “Setting the Input Format”
If you switch the input signal between 3G and SD/HD, the LV 5333 performs a system
configuration and may take about 30 seconds for the switching to finish.
The connectors are terminated internally at 75 Ω, so there is no need to connect terminators
to them. Connect cables with a characteristic impedance of 75 Ω.
