Serial Digital Interface Component Test Signal Generator & Receiver SDIT270

A precision source of 4:2:2 component digital test signals, the SDIT270 with its features is the ideal choice for production and development applications.
Main Features:

4:2:2 component test signal at 270 Mbps;
Test Signal 1: Full Field 75% Color Bars (EBU Bars in 625/50, Color Bars in 525/60);
Test Signal 2: Flat Field, Black – PAL and NTSC;
Test Signal 3: SDI pathological – EQ pathological, according to SMPTE RP178, PAL and NTSC;
Test Signal 4: SDI pathological – PLL pathological, according to SMPTE RP178, PAL and NTSC;
Visual indication of the test pattern generator operation – PLL Lock indicator;
PLL Receiver locks at 4 different data rates – 143, 177, 270 and 360 Mbps;
Visual indication of the receiver signal data rate;
No_TRS (Missing Timing Reference Signal TRS) error check – No valid digital video indication;
TRS_Error (New sync position of the TRS) error check – Sync alignment error indication;
Monitor Output for Sync pulse observation or error counting;
