Min signal level is 13dB below the nominal minimum PAL signal level of 60dBuV
| Signal path and signal levels | |
|---|---|
| item | signal level (dbuV) at output of item |
| launch | 59 |
| 12dB attenuator | 47 |
| Labgear 22dB amp | 67 |
This is the same combination of equipment as the 59dBuV case, but in this example the loss is before, not after the amplifier. Although at this stage the difference is not great, a slight increase is grain is apparent
