The graphics display next to the display of the average power informs the user on whether the
measured values are within the GSM tolerance mask.
Measured values within tolerance mask.
Measured values outside tolerance mask.
Tolerance mask not evaluated.
CTSgo will not evaluate tolerances in the module test when the peak power measurement is the only
one active. The expected power for the power measurement and other parameters influencing the
burst analysis can be entered in a dialog which is displayed when the Burst analysis button is pressed.
With the Freeze button, the numeric and the graphics result display are frozen, ie the displayed values
are not updated. Remote control is however not interrupted. This status is terminated with the Continue
button.
The Power ramp button
permits to display a
popup window with the
display of the power
ramp. The graph shows
the power versus the bit
position. The CTS
measures the power
with fourfold oversamp-
ling so that four
measured values
(quarter bits) are
recorded within the time
frame for one bit. Next
to the power ramp that
is shown as a blue
curve, the tolerance
mask is displayed as
red curve. Since no
PCL is known in the
module test, the display
may slightly differ
compared with the
autotest measurement.
If the average power is
not measured in
parallel, the lowest
tolerance lines are not
displayed.
