while in Vector mode.
2.
Press the
VECTOR
button twice.
3.
Vertically position the baseline to zero IRE (% in PAL).
4.

VARIABLE GAIN
at the top position to 100 IRE (%).
NOTE:
The differential gain reading is the difference in % between the centers of the
peak and the valley of the waveform.
You select the differential phase function by pressing the
