<MeasType>
parameter value
Meas. type Description/Result
1 CPOWer Channel power Power integrated over the sample values defined by
a center frequency and a bandwidth; based on a
defined impedance; the result is given in mW
2 OBWidth Occupied band-
width
From the defined center frequency, symmetric sam-
ple value pairs to the left and right are integrated until
a user-defined percentage of the total power is
reached
3 SBWidth Bandwidth n dB down Bandwidth; the samples to the left and right
of the peak value are analyzed until the n dB threshold
is exceeded; the frequencies at which the threshold is
exceeded define the limits of the requested bandwidth
4 THD Total harmonic dis-
tortion
Power sum of the harmonic waves divided by the
power of the fundamental wave.
