frequency, and record the values in the Spectrum Analyzer Marker (dB) column.
6. Return the signal generator amplitude to −45 dBm, and set the signal generator frequency and the
spectrum analyzer’s center frequency to the next frequency listed in Table 3-9 and repeat the process
from step 2.
7. Repeat steps 2–6 until all of the frequencies have been measured and recorded (to the maximum signal
generator frequency).

Power Level Accuracy Check
Calculate the Actual Power Level
1. Calculate and record the Actual Power Level, in Table 3-9, as the sum of the Power Meter Reading for
−45 dBm and the Spectrum Analyzer Marker (dB) value.
For example:
•Power Meter Reading for −45 dBm at 2.516 MHz = −44.95 dBm
•Spectrum Analyzer Marker (dB) at 2.516 MHz and Power Level Setting at −85 dBm = −40.17 dB
•Actual Power Level at 2.516 MHz and −85 dBm: (−44.95) + (−40.17) = −85.12 dBm
2. Compare the calculated Actual Power Level value to the corresponding lim its.
