➢
Press the
CP/ACP STANDARD
softkey.
➢
Select
NADC IS136
from the list of standards and press

softkey.
➢
Set the
FAST ACP
softkey to

.
The R&S FSP performs the power measurement in 5 channels (in the useful
channel and in the two upper and lower adjacent channels).
5. Set the optimum reference level and RF attenuation for the measurement.
➢
Press the
ADJUST REF LEVEL
softkey.
The R&S FSP sets the optimum RF attenuation and the optimum reference
level on the basis of the measured channel power.
6. Select the peak detector and increase the sweep time to 10 s.
➢
Press the
TRACE
key.
➢
Press the
DETECTOR
softkey.
➢
Press the
DETECTOR MAX PEAK
softkey.
➢
Press the
SWEEP
key.
➢
Press the
SWEEP TIME
softkey and enter
10 s
.
The R&S FSP measures the adjacent channel power generated by the burst
edges and the modulation.

trum
The peak power display depends on the selected sweep time. The longer the
sweep time, the higher the probability of measuring the highest peak amplitude of
the signal.
With shorter sweep times, level dips can be seen in the time domain traces.
These level dips come from the burst characteristics of the signal. The numerical
results, however, indicate the peak amplitudes during the measurement in the
corresponding channel.
