±1 dB, 100 Hz to 20 kHz
Residual Jitter
5 £
2 ns [0.012 UI at 48 kS/s, 0.024 UI at 96 kS/s]
Spurious Jitter Products typically <0.003 UI [–50 dBUI] or 30 dB below
jitter signal, whichever is larger

Chapter 6: Specifications
48 Getting Started with ATS-2
4
System specification including contributions from both analyzer and generator. Valid at
32.0, 44.1, 48.0, 65.536, 88.2, and 96.0 kS/s only. Flatness may degrade at other
sample rates.
5
System specification valid only if (1) the jitter generator amplitude is turned off; (2) the
digital input is
³
1.0 Vpp (XLR) or
³
250 mVpp (BNC); and (3) the analyzer is set for
700 Hz–100 kHz bandwidth.
6
1 kHz ref. Flatness derates above 5 kHz by an additional ±0.02 dB in the 22.4 V, 45 V,
90 V, and 200 V input ranges.
