Unless otherwise specified, the following conditions apply when each measurement is made.
1. VIF, SIF blocks: No signal
2. C input: No. signal
3. Sync input: A horizontal/vertical composite sync signal
PAL: 43IRE, horizontal sync signal (15.625kHz) and vertical sync signal (50kHz)
NTSC: 40IRE, horizontal sync signal (15.734264kHz) and vertical sync signal (59.94kHz)
Note: No burst signal, chroma signal shall exist below the pedestal level.
