From T26A, a 50% white signal is input. Burst level is measured at T38. PB chroma video T15A T38 From T15A in PB and SP mode, a chroma signal 490 580 670 mVp-p Output level T26A down-converted from the NTSC chroma noise test signal (NTSC mode) (SP mode, burst 160 mVp-p) and mixed with a 4 MHz 300 mVp-p sine wave is input. From T26A, a 50% white signal is input. Burst level is measured at T38.

Under same conditions as for PVop-38, input chroma level is raised by +6 dB. T46 burst level is measured and compared to PVop-46. Under same conditions as for PVop-38, input chroma level is raised by –6 dB. T46 burst level is measured and compared to PVop-38. Under same conditions as for PVop-38, input chroma level is attenuated and input burst level is measured when chroma output at T46 goes off (compared to standard input 80 mVp-p) T38 measured with spectrum analyzer and compared to PVop-38 in killer condition as described above. Under same conditions as for PVop-38, T38 is measured with spectrum analyzer and 4.43 MHz component is compared to 5.06 MHz component. From T15A, down-converted chroma noise test signal mixed with 4 MHz, 300 mVp-p CW is input. From T26A, 50% white signal is input. –45 ° burst level at T38 is measured and compared to PVop-38 |
