    • 9 Refer to the Onboard signal processing (OSP) section for possible N values (with and without fractional resampling). Non-OSP decimation does not protect the acquired data from undersampling aliasing. Non-OSP decimation and OSP decimation are mutually exclusive.
    • 10 Internal VCXO, unlocked.
    • 11 Refer to your chassis documentation to ensure it meets this requirement.
    • 12 For information about manual adjustment, refer to the Synchronization Repeatability Optimization topic in the NI-TClk Synchronization Help; for additional help with the adjustment process, contact NI technical support at ni.com/support.
    • 13 Assumes 2-byte samples. In Complex data processing mode (only available when using onboard signal processing), each sample is 4 bytes, so this number is halved.
    • 14 Record length refers to the number of samples, or data points, the NI-SCOPE device acquires for each channel in a single acquisition.
    • 15 It is possible to exceed this number if you fetch records while acquiring data. For more information, refer to the NI High-Speed Digitizers Help .
    • 16 Non-OSP decimation does not protect against high-frequency aliasing. Non-OSP decimation and OSP decimation are mutually exclusive.
    • 17 For sample rates less than 9.155 kS/s, use an external sample clock or perform additional software decimation.
    • 18 Fractional resampling not available.
    • 19 Using a decimation rate of 1 (sample rate of 150 MS/s with internal clock) bypasses the filters in the OSP block.
    • 20 Gain <1 attenuates user data
    • 21 (-0.5 × Vertical Range) ≤ Output ≤ (+0.5 × Vertical Range)
    • 22 Undersampling can be used for carrier frequencies >75 MHz.
    • 23 MSK modulation, 270.833 kSymbols/s, 1024 symbols, gaussian, BT = 0.3.
    • 24 In this case, the direct path carrier frequency is 35 MHz using the NI PXIe-5450 as the source.
    • 25 QPSK modulation, 3.84 MSymbols/s, 1024 symbols, root raised cosine, alpha = 0.22.
    • 26 32 QAM modulation, 6.92 MSymbols/s, 1024 symbols, root raised cosine, alpha = 0.15.
    • 27 64 QAM modulation, 20 MSymbols/s, 1024 symbols, root raised cosine, alpha = 0.15.
    • 28 64 QAM modulation, 26.09 MSymbols/s, 1024 symbols, root raised cosine, alpha = 0.15.
    • 29 64 QAM modulation, 34.78 MSymbols/s, 1024 symbols, root raised cosine, alpha = 0.15.
