    Products not made by LeCroy are covered solely by the warranty of the original equipment manufacturer. Under the LeCroy warranty, LeCroy will repair or, at its option, replace any product returned within the warranty period to a LeCroy authorized service center.
  • Page 11 — infrequently — minor logic changes. However, be assured the LSA1000 itself is in full order and incorporates the most up-to-date circuitry. LeCroy frequently updates firmware and software during servicing to improve LSA1000 performance, free of charge during warranty.

  • Page 18 Long-memory LSA1000s allow operation at the highest possible sample rate, and over a far longer capture time. The LSA1000’s fidelity in reconstructing the input signal is affected mainly by these three parameters. The bandwidth must be sufficient to allow all the signal components to pass through the signal- conditioning system.

  • Page 19: Capture

    The captured input data signal is transferred to memory for measurement and analysis. Analog–Digital Conversion High-speed LSA1000 performance is made possible by the use of advanced flash ADCs whose vertical resolution guarantee a clear representation of the signal. These ADCs measure the voltage level at evenly spaced intervals and store the digitized value in high-speed dedicated memory.

  • Page 22 In Auto Mode: the LSA1000 automatically captures the signal without waiting for a trigger. NORM In Normal Mode, the LSA1000 will continuously capture the signal as long as a valid trigger is present. If not, the last signal is preserved. SNGL In Single-Shot Mode, the LSA1000 waits for a single trigger to occur, then captures the signal and stops acquiring.

  • Page 23: Measure

    Waveform mathematics can yield final answers instead of raw data. For example, inputs from voltage and current transformers can be multiplied together to calculate power. An important LeCroy LSA1000 feature is the ability to ‘daisy-chain’ math functions: a power trace can be integrated to calculate energy, for instance.

  • Page 24: Analyze

    About the LSA1000 Analyze The LSA1000 has the added ability to process and analyze data on-board. Once the analog signal has been converted into digital data, the data can be analyzed either by the LSA1000’s internal digitizer processor or by an external computer. Most current digitizers have a wide analysis spectrum built-in.

Users can exercise the full functionality of LSA1000 from the host PC using the following easy-to-use software tools. These tools also simplify users' programming development for own specific applications.

Determining Top and Proper determination of the top and base reference lines is Base Lines fundamental for ensuring correct parameter calculations.
  • Page 86 Once top and base are estimated, calculation of the rise and fall Fall Times times is easily done (Fig.1). The 90 % and 10 % threshold levels are automatically determined by the LSA1000, using the amplitude (ampl) parameter. Threshold levels for rise or fall time can also be selected using absolute or relative settings (r@level, fall@level).
  • Page 87 To avoid these bias effects, the instrument uses cyclic parameters, including crms and cmean, that restrict the calculation to an integer number of cycles. Determining Differential The LSA1000 enables accurate differential time measurements between two traces — for example, propagation, setup and hold Time Measurements delays (Fig. C–3).
