User Macro
The User Macro instruction brings up a list of current
user macros you can insert. Macros are inserted at the current line and
expanded at run time.
If the macro selected has parameters, a second pop-up menu will be
displayed to allow setting of the passed parameter values. Parameters are
passed as 32 bit values and the most significant bits are truncated when the
data is applied to labels with less than 32 bits.
Once inserted, the passed parameters of a macro may be altered by selecting
that macro again and changing the data. A macro can only be removed from
the sequence by using the delete field.
Repeat Loop The Repeat Loop instruction inserts the start and end of a
repeat loop using the current vector row as the data. Once the loop has
been created, vectors can be inserted or copied into the loop to change
the size. A repeat loop will be expanded at run time into individual
vectors. The number of repetitions of the loop (maximum 20000) is set
when the repeat is first inserted into the sequence and can be altered by
selecting the start of the repeat to get the Repeat Count pop-up menu.
Both the start and end of a repeat loop will be removed from the
sequence if either is included in the delete block.
Break The Break instruction causes a break at the current vector. In
single run mode, this instruction halts the sequence and holds the
outputs at the break vector's value. In repetitive run mode, this
instruction pauses the sequence at the current vector momentarily, then
continues. The duration of the pause is dependent on the activity of
other modules in the frame.
Signal IMB The Signal IMB instruction creates a signal for the IMB bus
of the 16500B/C at the current vector, allowing the Agilent 16522A to
trigger other modules in the frame. Multiple signal IMB instructions may
be placed in the sequence, but only the first signal IMB will be executed.
