Electrical Sampling Modules
6.
Perform the following substeps for all frequencies listed in the
Frequency
column of the following table:
a.
Calculate the Adapter Loss as the difference between the
Reference level
(with adapters)
column and the
Reference level (no adapters)
column in
the following table:
Adapter Loss = (Ref level with adapters) - (Ref level no adapters)
b.
Record the calculation results in the
Adapter Loss
column of the following
table.
c.
Calculate the module response using the values in the
Measured level
column and the
Reference level
column in the following table as:
Module Response = (Measured level) – (Ref level with no ad
Adapter Loss/2)
Module Response = (Measured level) – (Ref level with ad Adapter
Loss/2)(Measuredlevel)
−
(Re
fl
evelwithadapters) + (AdapterLoss) ÷ 2
d.
Record the calculation results in the
Response
column in the following
table.
7.
Find the maximum and minimum power points between the 50 MHz and
65 GHz points in the
Response
column as shown in the following table.

Only perform checks up to the maximum bandwidth of the module under test.
8.
Note the power at 50 MHz calculated as the module response recorded in the
table of the procedure
Analog Bandwidth to 50 GHz.
(See Table 8.) You will
use the 50 MHz power in the next step.
9.
Find the maximum power and minimum power in the
Response
column of
the table. (See Table 9.) Check that the following statements are true (the
speci
fi
cation is ±3.0 dB referenced to the 50 MHz):
The maximum power minus the 50 MHz power is less than +3.0 dB.
The minimum power minus the 50 MHz power is greater than –3.0 dB.
10.
Repeat the Setup and Test sections for all bandwidth settings.
