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 ilxed 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 fixed marker. Its stimulus and

response values can then be changed using the llxed., marker menu, which is accessed with *e ~~~~~~~~~~~~
