Audio Precision 2700 Series User Manual

Digital Signal Generator
Available only in the SYS-2720 and SYS-2722 configurations. The 2700 series
digital generator consists of a DSP signal generator, hardware impairment generators
and processing (for example, variable risetime and induced jitter), and digital output
stages supporting the most popular formats.
Except for arbitrary and Pass Thru waveforms, the embedded output signals and the
digitally generated analog output signals are independently selectable and concurrently
available. If both digital and analog outputs are selecting arbitrary waveform, it must
be the same one. If Pass Thru waveforms are selected for both analog and digital
generators, they must be at the same sample rate.
