7.8 CDMA IF Filter Analysis Function
7-90
{CDMA GATE START [ ]}: Sets the start time of the CDMA IF filter gate.
{CDMA GATE STOP [ ]} : Sets the stop time of the CDMA IF filter gate.
{GATE SHAPE [ ]} : Calls the CDMA IF filter gate shape menu (see ).

Each channel can be set individually.
{MAXIMUM} : Specifies the 4-term Blackman-Harris type. The
maximum attenuation can be obtained.
{WIDE} : Specifies the 3-term Blackman-Harris type.
{NORMAL} : Specifies the 2-term Hamming type.
{MINIMUM} : Specifies the rectangular type.
{CDMA IF} : Specifies a type which is optimized for the CDMA IF
filter.
CDMA IF filter magnitude menu
{CDMA FILTER ANALYSIS [ ]}: Turns the magnitude analysis function ON or OFF.
When this function is turned ON, the following
analysis results are displayed:
Note: This function cannot be used with the filter analysis of marker analysis function
or the statistical analysis function.
C. F : Displays the center frequency between the pass bandwidth specified by
the loss from the peak value.
B. W : Displays the pass bandwidth.
I. L : Displays the insertion loss (the peak value).
RPL : The difference between the peak and lowest local minimum values.
ATTN1 : Displays the guaranteed attenuation. The range calculated by
comparing the points where the addition to and the subtraction from the
CF of ATTN FREQ1 intersects the trace. These points are then used to
calculate range between them and the I.L. The shorter of these two
ranges is designated as ATTN1.
ATTN2 : Displays the guaranteed attenuation. The range calculated by
comparing the points where the addition to and the subtraction from the
CF of ATTN FREQ2 intersects the trace. These points are then used to
calculate range between them and the I.L. The shorter of these two
ranges is designated as ATTN2.
P. L : When the phase analysis function (CDMA IF filter analysis) is ON, the
phase linearity is calculated and the result is displayed.
{WIDTH VALUE} : Specifies the bandwidth to be searched using the
loss (X dB) from the peak value.
{ATTN FREQ1} : Specifies the first frequency for the guaranteed
attenuation measurement. The guaranteed
attenuation is not measured when this frequency is
set to 0 (zero) (as the guaranteed attenuation
