Electrical Sampling Modules
7. Record amplitude reading readout and use the value as AMPLITUDE (Volts)
in the step that follows.
8. Convert Volts to dBm as follows:
Vp=(AMPLITUDE/2)
V
RMS
=Vp/SQRT (2)
P1=V
RMS
*V
RMS
/50
dBm=10*log(P1/0.001)
9. Record dBm in the Measured level column of the table. (See Table 8.)
10. Repeat steps 2 through 9 for all frequencies listed in the Frequency column
of the table. (See Table 8.)
11. Calculate the DUT response as the difference between the Measured level
column and the Reference RF level column in the table (See Table 8.) as:
(Measured level) - (Reference RF level)
Record the calculation results in the DUT Response column of the table. (See
Table 8.)
12. Calculate all frequencies listed in the Frequency column of the table. (See
Table 8.)
13. Find the maximum and minimum power points in the DUT Response column
of the table. (See Table 8.)
14. The maximum power minus the power at 50 MHz should be less than +3.0 dB.
The minimum power minus the power at 50 MHz should be greater than
–3.0 dB. The speci
fi cation is ±3.0 dB referenced to 50 MHz.
15. Repeat the Setup and Test sections for all bandwidth settings that are valid for
the module under test.
16. Repeat the Setup and Test sections for channel 2.
17. Disconnect the test setup.
