The CS328A excels in providing high-resolution data capture for a variety of applications..

  • Detail
  • Special Features
  • Specification

The Cleverscope CS328A is a versatile oscilloscope designed for precision signal measurement and analysis, with the capability to perform high-resolution measurements across different applications. With sampling configurations of 10, 12, and 14 bits, it can achieve an effective number of bits (ENOB) of up to 14.1, with a signal-to-noise ratio (SNR) of over 86 dB when using moving average filters.

Key features include a dynamic range of over 94 dB in non-averaged mode, and the cross-talk performance remains below 76 dB, making it suitable for both high-speed and low-level signal applications. Additionally, the oscilloscope minimizes ground noise, thanks to a carefully designed acquisition unit construction, including dual ground planes and shielded casings.

The Moving Average Resolution Enhancement further improves the SNR by reducing noise levels, making it ideal for applications requiring precise signal analysis. External and internal noise sources are accounted for, with both handled effectively to preserve the integrity of the measurements.

  • Resolution Options: Available in 10, 12, and 14-bit sampling configurations.

  • Signal to Noise Ratio (SNR): Achieves an effective number of bits (ENOB) up to 14.1 with averaging.

  • Dynamic Range: Offers extensive dynamic range with high sensitivity and noise reduction.

  • Cross Talk Performance: Maintains cross-talk levels of up to 76 dB, ensuring accurate measurements of signals.

  • Ground Noise Minimization: Designed with built-in shielding and optimized construction to minimize ground noise interference.

  • Advanced Averaging: Moving average filtering enhances resolution and reduces noise by up to 21 dB.

  • Wide Bandwidth: Features a 100 MSPS sampling rate and 20 MHz bandwidth for versatile signal analysis.

  • Built-in Spectrum Display: Spectrum analysis capability for comprehensive signal analysis.
