R T A Memories R T A Averaging F unctions
T he IE -45 offers powerful Memory Management functions (see manual for details).
B asically, there are nine S cratch Memories, an Average memory and a P referred
C urve memory available via on-screen controls, but spectra captured in these
temporary S cratch Memory slots can be renamed and stored in virtually unlimited
number. T he various averaging functions of the IE -45 constitute one of the most powerful
feature sets in the instrument. S patial averaging is made easier (you don't have to
average one memory with another). Averaging samples can be automatically or
manually collected. T he user can select Arithmetic or P ower averages. S ee the
manual for a complete outline of the IE -45's powerful averaging features.
