Functional Tests
BBIQ Input Frequency Response (Option BBA only)
16.Set the RF Signal Generator frequency to 250 kHz
17.Connect the BNC Cable between the RF Signal Generator RF Output and
the I input on the X-Series analyzer, see Figure 18-9
18.Connect the 50 Ohm termination to the I input on the X-Series analyzer,
see Figure 18-9
19.Press Peak Search on the X-Series analyzer. Record the marker amplitude
reading in Table 18-10 for the I Input at 250 kHz.
20.Set the RF Signal Generator to each of the remaining frequencies listed in
Table 1, up to the maximum IQ bandwidth of the X-Series analyzer. At
each frequency, do the following:
a. Press Peak Search
b. Record the marker amplitude reading in Table 18-10 for the I Input
at the current RF Signal Generator frequency
21.Connect the BNC Cable between the RF Signal Generator RF Output and
the Q input on the X-Series analyzer, see Figure 18-10
22.Connect the 50 Ohm termination to the Q input on the X-Series analyzer,
see Figure 18-10
23.Set the RF Signal Generator frequency to 250 kHz.
24.Press Peak Search on the X-Series analyzer. Record the marker amplitude
reading in Table 18-11 for the Q Input at 250 kHz.
25.Set the RF Signal Generator to each of the remaining frequencies listed in
Table 18-11, up to the maximum IQ bandwidth of the X-Series analyzer. At
each frequency, do the following:
Press Peak Search
Record the marker amplitude reading in Table 18-11 for the Q Input at the
current RF Signal Generator frequency
