(5) SG generation position setting (valid only during TRIG drive)
The SG pulse (ternary value output of the V2A and V2B pulses) generation position during TRIG drive can
be selected from 2 to 2048H counting from the next HD after the falling edge of the TRIG pulse by the D10
to D0 setting. The SG generation position (H) for each serial setting value is shown below.
(For details, see Chart-4 to Chart-7.)

When high-speed sweep is on, a SG generation prohibited area exists. When this area is designated, the SG
pulse is generated at the position indicated below. When the drive mode during TRIG pulse input is:
DRAFT mode: When the prohibited area 2 to 57H is designated, the SG pulse is generated at 58H.
FINE/TRIGOUT mode: When the prohibited area 2 to 214H is designated, the SG pulse is
VD input is not accepted until 2H after the SG generation position (H), and is accepted from 3H onward.
(Example: When the SG generation position is 58H, VD input is not accepted from 1 to 59H, and is
accepted from 60H onward.)
(6) SUB setting (valid only during TRIG drive)
The number of SUB pulses during TRIG drive can be selected by the D7 to D0 setting. The number of
SUB pulses for each serial setting value is shown below.

When high-speed sweep is off, the number of SUB pulses is two regardless of the drive mode during
TRIG pulse input and the SUB setting value.
When high-speed sweep is on, the maximum number of SUB pulses is as follows according to the drive
mode during TRIG pulse input. Setting values in excess of the maximum number of pulses are fixed to
the maximum number of pulses. (For details, see Chart-4 to Chart-7.)
DRAFT mode: Max. 58 pulses
FINE/TRIGOUT mode: Max. 215 pulses
