"User Defined" The internally generated clock reference signal is used. The sample
rate is calculated and displayed in the field "Value".
"Digital I/Q
Out" An external clock reference signal is used. The clock signal is directly
fed in via pin CLK2 of the digital output interface (option R&S
SMBV-
K18, Digital Baseband Connectivity). The sample rate is estimated
and displayed in the field "Value".
Note: Estimation works best if the sample rate is close to the user
defined value.
Remote command:
[:SOURce<hw>]:IQ:OUTPut:DIGital:SRATe:SOURce
on page 757
Sample Rate Value - Digital I/Q Output
Sets or displays the sample rate of the digital I/Q output signal, depending on the
selected sample rate "Source".
Remote command:

5.8.3 Signal Output
The level of the output signal is set in the "Signal Output" section. For entering the
value, level type "Peak Level" or "Level" can be selected.
Set Level Via
Selects the level type (peak level/level) that is used to set the signal level. The entry
field is activated in the status bar and the value can be edited directly. Either the "Peak
Level " or the "Level" entry field can be edited in a path.
The level entry fields and the corresponding units are displayed in the status bar.
"Peak Level" The signal level is expressed in terms of a peak envelope power
value (PEP).
"Level" The signal level is expressed in terms of a rms value.
The level always refers to the RMS value of the output signal without
noise, even if the AWGN generator is activated.
Remote command:
[:SOURce<hw>]:IQ:OUTPut:POWer:VIA
on page 756
Peak Level - Digital I/Q Out
The signal level is expressed in terms of a peak envelope power value (peak level).
The level entry fields and the corresponding units are displayed in the status bar. The
level display always refers to both signal components (SQR(I
2
+Q
2
)).
Remote command:

Level - Digital I/Q Out
The signal level is expressed in terms of an rms level value.
