f) Press the "Adjust Settings" softkey.
The settings for the frequency span, the bandwidth (RBW and VBW) and the
detector are automatically set to the optimum values required for the measure-
ment.

bandwidth.
6. Stabilize the measurement result by increasing the sweep time.
In the "Ch Power ACLR" menu, press the "Sweep Time" softkey and enter 1 s.
The trace becomes much smoother because of the RMS detector and the channel
power measurement display is much more stable.
6.4.5.3 Measuring Phase Noise
The R&S ESR has an easy-to-use marker function for phase noise measurements.
This marker function indicates the phase noise of an RF oscillator at any carrier in dBc
in a bandwidth of 1 Hz.
