LeCroy SPARQ-4004E Signal Integrity Network Analyzer
SPARQ is the ideal instrument for characterizing multi-port devices common in signal integrity applications at a fraction of the cost of traditional methods.
It is ideal for:
• Development of measurement-based simulation models
• Design validation
• Compliance testing
• High-performance TDR
• PCB testing
• Portable measurement requirements
High-bandwidth, Multi-port
S-parameters for the Masses S-parameter measurements are most often produced by the vector network analyzer (VNA), a difficult instrument that is beyond many budgets. SPARQ is very affordable and simplifies measurements, making S-parameters accessible to all.
PC-based, Small and Portable
Traditional instruments that produce S-parameters are large and fundamentally stationary. The SPARQ, in contrast, is small, lightweight and portable. It connects to any standard PC through a USB 2.0 interface, allowing SPARQ to run where computing power is easily upgraded.
S-parameters, Quick
VNA measurements begin with the unpleasant and complex task of calibration. This involves multiple connections that can produce misleading results due to operator error. The SPARQ provides calibrated measurements with a single connection to the DUT and offers simple setup choices. Start and complete the entire measurement with a single button press.
Internal Calibration
SPARQ takes a revolutionary approach to calibration by building in calibration standards. This enables measurements to be made eliminates the need for additional expensive electronic calibration (ECAL) modules. Calibration proceeds quickly without user intervention, so one can calibrate often without resorting to the use of out-of-date saved calibrations.
Key Features:
- Provides complete S-parameter measurements
- Measures from DC to 40 GHz
- One-button-press internal OSLT calibration
- Analyzes in both frequency and time domain
- Produces mixed-mode and single-ended simulation- ready S-parameters
- Remove effects from fixtures, connectors and launches using either Time Gating or S-parameter de-embedding
- Inherent TDR/TDT capability and preview modes for quick checks and debugging
- Characterizes crosstalk of multi-lane differential structures
- Available at a fraction of the cost of other network analyzer solutions
