Power Level Accuracy Check

Chapter 328

Calculate the Actual Power Level

1. Calculate and record the Actual Power Level, in Table 3-3, as the sum of the Power Meter

Reading for

−

15 dBm and the Spectrum Analyzer Marker (dB) value.

For example:

• Power Meter Reading for

−

15 dBm at 2.516 MHz =

−

14.95 dBm

• Spectrum Analyzer Marker (dB) at 2.516 MHz and Power Level Setting at

−

85 dBm =

−

70.17 dB

• Actual Power Level at 2.516 MHz and

−

85 dBm: (

−

14.95) + (

−

70.17) =

−

85.12 dBm

2. Compare the calculated Actual Power Level value to the corresponding limits.
