Note:
The connected instrument is indicated only, if the connection is properly estab-
lished and signal transmission is active.
SCPI command:
5.9.1.2
Frequency and Phase Offset
A frequency and a phase offset can be added to the baseband signal. Define the param-
eters "BB Input Frequency Offset" and "BB Input Phase Offset" in the "Baseband In/
Out" block menu.
Frequency Offset
Enters the frequency offset for the external baseband signal.
The offset affects the signal on the output of the "Baseband In/Out" block.
It shifts the useful baseband signal in the center frequency.
The complex I/Q bandwidth of the shifted useful signal must not exceed 120 MHz in total
(see also
The following applies:
f
offset
- f
use
/2 >= -120 MHz /2 and f
offset
+ f
use
/2 <= +120 MHz /2
f
use
= the complex useful bandwidth of the I/Q signal before the offset.
f
offset
= frequency offset.
Note:
The bandwidth as shown above applies to the R&S SMBV, equipped with options
R&S SMBV-B10 or R&S SMBV-B50.
Option R&S SMBV-B51 provides a range of -30 MHz ... +30 MHz, i.e. -60 MHz /2 ... +60
MHz /2.
