[: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.
Parameters:
float
-40 to +40
0.01Hz

<Foffset>
Range:
Increment:
*RST:
Default unit:
BBIN:FOFF 2 MHz
sets a frequency offset of 2 MHz.
Example:
[:SOURce<hw>]:BBIN:GIMBalance <Gimbalance>
This command enters a gain to the Q component of the external baseband signal.
Parameters:
float
-3.0dB to +3.0dB
0.01dB
0dB
dB
<Gimbalance>
Range:
Increment:
*RST:
Default unit:
BBIN:GIMB -1.0dB
amplifies the Q component of the external input signal with -1.0
dB.
Example:
[:SOURce]:BBIN:IQSWap[:STATe] <State>
This command swaps the I and Q channel if set to ON.
Parameters:
0|1|OFF|ON
OFF
<State>
*RST:
BBIN:IQSW ON
swaps the I and Q channel of the external baseband signal.
