8.2.2 Measuring channel power
(Single Channel Power)
SpectrumSpectrum • Measurement • Single-Channel Power
You can determine a wideband value for the measurement values in a
defined frequency range using
Single Channel Power
mode. You can
therefore make channel power measurements.
To open the integration function:
 Press the
Measurement
softkey, then press the
Single Channel Power
softkey.
Figure 37:
Int. Val
: Shows the result of the integration.
NOTE:
The integration function takes all the spectral lines within the integration
range into account, including those which lie within the noise floor. The
result of this evaluation function is therefore very dependent on the intrinsic
noise level and therefore from the selected reference level if the signal
levels present are close to the intrinsic noise level.
Possible entry methods
The type of entry method is selected using the
Entry
softkey:
•
Numerical
: Numerical entry using the number keys and decimal point key
in the keypad.
•
Graphical
: The rotary control knob is used to enter the frequency limits.
