Snoop Pro Mini 3.0 Release Notes

Released: February 2026

What is new

Improved testing accuracy

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

Easier shielding plate change

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.
