8.1.3 Advanced display Time Step Stimulus Test
The advanced display mode can be
entered
by
clicking
on
the
box
"advanced"
on the left side of the test
screen. This test screen contains additional
information and features. This mode is
available for the current test result as well
as for the stored data.
Figure 37 displays the test result shown in
chapter 8.1.2, figure 38, in the advanced
display format.
During the test, the single measurement
sweeps are stored alternatively in the A-
and B-Buffer. It is possible to display data
within the A- and B-Buffers separately, by
selecting the “A+B” function located at
the left of the test screen. When this is
selected, the averaged data will be
displayed at the bottom and the data
stored within the separate A- and B-
Buffers will be displayed at the top.
The “Filter” function allows you to smooth the curves on the screen. The
cut-off frequencies of the filter are 163 Hz and 1930 Hz.
The boxes for the adjustment of the artifact limit and the amplitude of the
AEP display are located on the upper left part of the screen.
The actual value of the artifact limit is shown under
“Artifact-
limit”
. For example, in figure 39 the actual artifact limit is 20
μ
V. The artifact limit can be adjusted by clicking on the arrow
right of the Artifact-limit box. Values between 5
μ
V and 50
μ
V
are selectable. The display magnitude of the AEP’s (waves) is
shown under
“Amplitude”
. For example, in figure 39 the
actual amplitude is 1.0
μ
V.
The amplitude can be adjusted by clicking on the arrow right of the
Amplitude box. Values between 0.1
μ
V and 1.1
μ
V are selectable.
