3.1 Setting the Parameters
3-5
Example:
Suppose that the following parameters are set for this unit:
Output Level : −10 dBm
Digital Mod : On
System : Noise1
Noise Bandwidth : 7.68 MHz
Calculated Bandwidth : 3.84 MHz
From Formula (1),
Power within the calculated bandwidth
= RF output level + Calculated level
= −10 dBm + (−3.45 dB)
= −13.45 dBm
Therefore, the power within the calculated
bandwidth for the RF output is –13.45 dBm.
The power –13.45 dBm is displayed at “(Ab-
solute)”.
