Notes to Specifications
1. System specification including contributions from both generator and analyzer. Generator-only and analyzer-only
contributions are typically less.
2. Sample rate (SR) must be

27 kHz for specified performance. Jitter analyzer set for 700 Hz highpass response
per AES3-1992.
3. Digital generator word width must be set to 24 bits for specified performance; shorter word widths may degrade
performance.
4. DSP warping may significantly increase roll-off rate and lower ENBW.
