What are the details related to using the N6030A arbitrary waveform generator predistortion?

The built-in predistortion scales the data to guarantee that you never get a DAC over-range condition. Typically, it gives up 2-3 dB of range. This is important because less power out of the N6030A means less leveled output power from the PSG with Option 065. Making sure that the N6030A uses the full range of the DAC ensures that the PSG can provide a minimum leveled output signal of 0 dBm! Higher leveled output power of 5-10 dBm (depending on the signal and the RF frequency) is achievable.
