The color bar signal in Figure 5-3 shows excellent amplitude characteristics and no attenuation of colors with respect to the luminance signal.

The CCIR330/5 test pattern requires one of the greatest dynamic ranges, and therefore tests the OPA361-Q1 output voltage swing capability. The scope plot shown in Figure 5-4 has been taken with a 2.8V supply and shows no clipping on the top side of the signal.

The multiburst test patterns have different sine-wave burst sections with the following frequencies: 0.5MHz, 1MHz, 2MHz, 4MHz, 4.8MHz and 5.8MHz with 420mVPP. There is no visible attenuation even at the highest frequencies, which indicates a very flat frequency response of the OPA361-Q1. As shown in Figure 5-5 and Figure 5-6, the top line illustrates the full signal and the bottom line is a more detailed view of the last three sine wave bursts.

The CCIR17 test pattern contains a 2T and a 20T pulse, as shown in Figure 5-6. The 2T pulse is used to check for pulse distortion and reflection, and the 20T pulse is used to check for amplitude and group delay between chrominance and luminance. Neither pulse exhibits any distortion or group delay artifacts.
