Amplitude
Sets the level of the RF signal.
The value is offset-free and corresponds to the level at the RF A/RF B connector.
Note: Suppressed values in the status bar
For security concerns or certain operating modes, you can hide the frequency and
level display in the status bar.
●
The display has been disabled for security reasons.
See:
– Annotation Frequency
– Annotation Amplitude
The display is disabled when:
– List mode is running, see Chapter 7.6, "Varying the RF Signal in List or Sweep
Mode", on page 457.
– Digital only signals are generated, see the user manual "R&S SMW-K551 Gen-
eration of Digital "Slow IQ" Signals"
See Chapter 7.3.4.1, "Displayed RF Frequency and Level Values with Downstream
Instruments", on page 440.
Remote command:
[:SOURce<hw>]:POWer:POWer on page 1099
Note: The SCPI command [:SOURce<hw>]:POWer[:LEVel][:IMMediate][:
AMPLitude] sets the level of the "Level" display.
This means, the level containing offset.
Digital Attenuation
Attenuates or raises the level of the internal, digitally modulated I/Q baseband signals,
and thus the level of the RF signal accordingly.
The function allows fast level changes of the internal I/Q signals. You can determine an
attenuation value between -3 dB and +80 dB. The instrument calculates the digital
attenuation to the Level
PEP
and the Level
rms
as follows:
