BBIQ Input Frequency Response (Option BBA only)
Procedure
19.Press Peak Search on the X-Series analyzer. Record the marker amplitude
reading in Table 9-1 for the I Input at 250 kHz.
20.Set the RF Signal Generator to each of the remaining frequencies listed in
Table 9-1, 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 9-1 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 9-3
22.Connect the 50 Ohm termination to the Q input on the X-Series analyzer,
see Figure 9-3
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 9-2 for the Q Input at 250 kHz.
25.Set the RF Signal Generator to each of the remaining frequencies listed in
Table 9-2, 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 9-2 for the Q Input at the
current RF Signal Generator frequency
