11.3. Adjustment of TG Phase
You can adjust phase and drive ability of high frequency TG pulse (H1, H2, RG, XSHP, XSHD, XRS). You can
acquire a suitable CCD signal by adjusting phase and drive ability, and it can be well sampled. Since these
phases may change with the composition of a substrate, or methods of wiring, please adjust a phase if
needed.
11.3.1. Adjustment method of phase and drive ability
Adjustment of delay
Delay can be changed by the parameter of
Table 11.3-1
. Moreover, as shown in
Table 11.3-2
, a setting value
is changed, and the amount of delay can be adjusted. Please refer to
Fig 11.3-1
about the situation of change.
