turns off the delta marker mode, so that the values displayed
for the active marker are absolute values.
establishes marker 1 as a reference. The active marker stimulus
and response values are then shown relative to this delta
reference. Once marker 1 hasbeen selected as the delta
reference, the softkey label $ ,i&? ': i 1:: is underlined in this
menu, and the marker menu is returned to the screen. In the
graticule.
makes marker 2 the delta reference. Active marker stimulus
and response values are then shown relative to this reference.
makes marker 3 the delta reference.
makes marker 4 the delta reference.
makes marker 5 the delta reference.
sets a user-specified fixed reference marker. The stimulus and
response values of the reference can be set arbitrarily, and can
be anywhere in the display area. Unlike markers 1 to 5, the
fixed marker need not be on the trace. The fixed marker is
indicated by a small triangle A, and the active marker stimulus
and response values are shown relative to this point. The
notation "AREF=A" is displayed at the top right comer of the
graticule.
Pressing this softkey turns on the tied marker. Its stimulus and
response values can then be changgl usin# the ffxed marker
set to the current active marker position, using the ~~~~
