Snoop Pro Mini 3.0 Release Notes

Released: February 2026

What is new

  • The testing accuracy is improved by reducing the unit-to-unit variance compared to the predecessor
    • Snoop Pro Mini 2.0: ± 1.0 dB typical
    • Snoop Pro Mini 3.0: ± 0.5 dB typical
  • The shielding plates are easier to change because the magnets holding the plate are replaced with less powerful ones.
  • Integrated strobe light
    • Illuminates the tag from below, enabling precise visualization of the tag antenna position and accurate setting of the test start location.
    • Flashes a red light for failed tags.
    • On/Off switches for Strobe and Fail indicator
    • The strobe functionality requires the Station IO cable version 1.2, which limits compatible lane controller versions: lane controller versions 1.1 and 2.0 support the strobe functionality.
    • Snoop Pro Mini 3.0 can be used without the strobe functionality to measure only RF performance.
    • Note: Use of the strobe light is recommended only during production setup and triggering position verification, as certain RFID ICs may be sensitive to high-intensity light.

Backward Compatible

  • Snoop Pro Mini 3.0 is drop-in compatible in RF performance with Snoop Pro Mini 2.0, except in cases where a narrow tag is positioned close to the edge of a large shielding plate opening, Snoop Pro Mini 3.0 exhibits better coupling and higher sensitivity.
  • Mechanically, largely backward compatible with Snoop Pro Mini 2.0.
    • The same shielding plates can be used.
    • Features the same attachment holes in the bottom plate.
    • Note: Due to the integrated strobe functionality, the Strobe RJ45 connector slightly increases the Snoop Pro Mini 3.0’s dimensions compared to the previous version.
