The @label parameter must begin with a '@' character. Note that labels when referred
to in a
JUMP_
.. instruction do not have a following colon (':') character. Jumps may be
made backwards or forwards.
The
JMASKZ
and
JMASKNZ
instructions are most useful for testing Channel Status
fields.
Notes on the 'value' parameter:
The value parameter can be expressed in a variety of units depending on what type of
result is being tested. Usually there is a 'user-friendly' unit which requires the use of a
suffix. Omitting the suffix causes the DSA-1's internal 'raw' units to be used:
Time (
MEAS_FS_JITTER, MEAS_DATA_JITTER, MEAS_EYE_NARROW
)
Use units of nanoseconds, with the suffix
'ns'
;
Raw DSA-1 units are multiples of 1/64th of a nanosecond;
JUMP_IF_GREATER( 6.5ns, @bad_jitter )
is equivalent to
JUMP_IF_GREATER( 4160, @bad_jitter )
