54. Comms Frequency Response (Option BAC or BAH)
Part 2: Measuring Frequency Response, 800 MHz to 1000 MHz,
1700 MHz to 2000 MHz (0 dB, 5 dB, 10 dB, 25 dB, and 40 dB
Attenuation)
Figure 2-75 Comms Frequency Response Test Setup
1. This procedure will be performed several times with various
combinations of input attenuation, resolution bandwidth, and
preamp settings as described in Table 2-109. Make 6 copies of Table
2-110 (7 copies if the analyzer is equipped with the preamp,
Option 1DS). Label each copy with the information listed in Table
2-109.
2. Remove the reference sensor (Channel A sensor) from the power
