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.
C4FM, OQPSK,
4FSK
2bps–100Mbps 2bps–50Mbps 2bps–25Mbps
IS95 OQPSK,

128QAM 7bps–350Mbps 7bps–175Mbps 7bps–87.5Mbps
256QAM 8bps–400Mbps 8bps–200Mbps 8bps–100Mbps
Modulation Type Bit Rate Range for Internal Data (bit rate = symbol rate x bits per symbol)
20 ns
32QAM (5 bits per symbol)
100 ns
10 Msps
10.000001 Msps
bit rate = bits per symbol x symbol rate
NOTE: The pulse widths values are only for example purposes. The actual width may vary from the above values.
