SMBV100A
611 Operating Manual 1407.6062.32 ─ 08
Indicates the ID of an externally connected R&S Instrument or R&S Device.
Return values:
<CDevice> string
Example:
BBIN:CDEV
queries the connected device ID.
Usage: Query only
[:SOURce]:BBIN:CFACtor <CFactor>
This command enters the crest factor of the external baseband signal.
Parameters:
<CFactor> float
Range:
0 to 30
Increment: 0.01
*RST:
0
Default unit: dB
Example: BBIN:CFAC 10
enters a crest factor of 10 dB for the external baseband signal.
[:SOURce<hw>]:BBIN:DIGital:ASETting:STATe <State>
Activates automatic adjustment of the baseband input signal.
The R&S SMBV receives PEP, level and crest factor values directly from the connected
transmitter and recognizes changes automatically.
Parameters:
<State> 0 | 1 | OFF | ON
*RST:
0
Example: BBIN:DIG:ASET:STAT ON
switches on automatic adjustment of the baseband input signal.
[:SOURce]:BBIN:FOFFset <FOffset>
This command enters the frequency offset for the external baseband signal. The offset
affects the signal on the output of the "Baseband" block.
The complex I/Q bandwidth of the shifted useful signal must not exceed 80 MHz in total.
The following applies:
f
offset
-(f
use
/2) => -(80/2) MHz and f
offset
+(f
use
/2) >= +(80/2) MHz
f
use
= the complex useful bandwidth of the I/Q signal before the offset.
f
offset
= frequency offset.
