Real–Time Commands
Custom Subsystem–Option 431([:SOURce]:RADio:CUSTom)
residual phase present in the signal, the DAC Over–Range Protection feature
will automatically prevent DAC over-range errors from occurring by scaling the
signal down by 1/square root of 2.
Key Entry

:BBT

[:SOURce]:RADio:CUSTom:BBT <val>
[:SOURce]:RADio:CUSTom:BBT?
This command changes the bandwidth-multiplied-by-bit-time (BbT) filter
parameter.
The filter BbT value can be set to the maximum level (1) or in between the
minimum level (0.100) and maximum level by using fractional numeric values
(0.101–0.999).

:BRATe

[:SOURce]:RADio:CUSTom:BRATe <val>
[:SOURce]:RADio:CUSTom:BRATe?
This command sets the bit rate in bits per second (bps–Mbps). The maximum
bit rate depends on the modulation type as shown in the following tables.
The IQ digital data stream is shaped by a FIR filter.
To change the modulation type, refer to
When the bit rate is changed, the signal generator reconfigures the baseband
generator. The time required to reconfigure the baseband generator is
inversely proportional to the bit rate: lower bit rates require more time.
