Command/Query

DESCRIPTION

The HOR_MAGNIFY command horizontally expands the selected
expansion trace by a specified factor. Magnification factors not within

the range of permissible values will be rounded off to the nearest legal
value.

The VAB bit (bit 2) in the STB register (see table on page 225) is set
when a factor outside the legal range is specified.

The HOR_MAGNIFY? query returns the current magnification
factor for the specified expansion function.
