HOR_MAGNIFY, HMAG
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 closest
legal value.
If the specified factor is too large for any of the
expanded traces (depending on their current
source), it is reduced to an acceptable value and
only then applied to the traces. The VAB bit (bit 2)
in the STB register 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.
COMMAND SYNTAX
<exp_trace>: Hor_MAGnify <factor>
<exp_trace>: = {TA, TB, TC, TD}
<factor> : = 1 to 2,000,000 The range of <factor> is
related to the current timebase and the range of the
timebase.
QUERY SYNTAX
<exp_trace> : Hor_MAGnify?
RESPONSE FORMAT
<exp_trace>: Hor_MAGnify <factor>
EXAMPLE
The following instruction horizontally magnifies
Trace A (TA) by a factor of 5:
