Electrical Sampling Modules
Adapter-Characterization
Setup
Install the test setup to characterize the adapter:
Figure 18: Adapter characterization setup
1.
Connect the 10 dB attenuator to the Synthesized signal generator. Connect
the other end of the cable to the 10 dB attenuator.
2.
Connect the other end of the 10 dB attenuator to a 2.4 mm female-to-female
adapter.
3.
Connect the other end of the 2.4 mm female-to-female adapter to the power
sensor.
4.
Connect the other end of the power sensor to the power meter.
Adapter Characterization
Measurements
Follow this procedure to characterize the reference level with the adapters:
1.
Set the signal frequency and the power meter frequency to each of the
frequencies listed in the
Frequency
column of the table. (See Table 5.)
NOTE.
You only need to characterize the reference level up to the maximum
bandwidth of the module under test.
2.
Record the readings on the power meter in the
Reference level with the
adapters dBm
column of the table. (See Table 5.)
3.
Calculate and record the
2.4 mm female-to-female adapter loss dB
in the table
for all frequencies listed as follows (See Table 5.):
((Reference level with adapters dBm) - (Reference level dBm)) /2
