continuous data stream. This means that it does not apply to a downloaded PRAM file type (covered later in this chapter).

In parallel mode, for a 256QAM modulation scheme, Custom has the capability to reach a data rate of up to 400 Mbps. The FIR filter width is what determines the data rate. The following table shows the maximum data rate for each modulation type. Because the signal generator’s maximum symbol rate is 50 Msps, a modulation scheme that has only 1 bit per symbol is always processed in serial mode.

The only external effect of the parallel mode is in the EVENT 1 output signal. In serial and parallel mode, the signal generator outputs a narrow pulse at the EVENT 1 connector. But in parallel mode, the output pulse width increases by a factor of bits- per- symbol wide, as shown in the following figure.
