1. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed.
2. Connect the Type-N cable between the RF Input and the tracking

3. Set the analyzer by pressing the following keys:
FREQUENCY, 50 MHz
FREQUENCY, CF Step, 150 MHz
SPAN, Zero Span
System, Alignments, Auto Align, Off

4. Disconnect the Type-N cable.
5. Zero and calibrate the power meter with the power sensor in log
mode (power reads out in dBm), as described in the power meter
operation manual.
6. Connect the 50 Ω power sensor to the RF OUT 50 Ω on the analyzer.
See Figure 2-63.
7. Set the power meter to relative mode, as described in the power
meter operation manual. Power levels now read out in power level
relative to the power level at 50 MHz.
Perform the next four steps for each measurement value in Table 2-97.
8. Set the center frequency of the analyzer according to the values in
