LAPLACE INSTRUMENTS RF SENSORS & PROBES

Laplace Instruments Sensors/Probes Products

Laplace supplies a range of RF field measurement tools….

• RF sensors for EMC applications

• RF current clamps for EMC applications

 

RF sensors

A range of miniature isotropic sensors connected via fiber optic cable to avoid any interaction with the RF field. This ensures that measurements are of the highest integrity, unaffected by any conductive cables or associated meter body. These Sensors are available for the use with synthesizers as part of an immunity test system in an EMC test chamber.

 

  • • Ideal for use in EMC immunity test chambers
  • • Provides real time feedback for stress level control
  • • Includes fiber optic interface with RS232 and USB outputs
  • • Total and individual axis outputs (Vector summation or X, Y, Z)
  • • Miniature size
  • • 2 versions: battery powered and laser powered.
  • • Battery powered version includes battery charging station. 12 hour operating time before recharging necessary.
  • • Laser powered version for continuous operation. Battery charging not required. Laser is included with the fiber optic interface.
  • • Standard fiber optic cable length is 10m. Longer cables available to order.

Bulk Current Injection clamp (BCI)

Used with BCI and/or EMClamp injection methods for monitoring the injected RF current. IEC61000-4-6 requires that the injected current should not exceed that which would be injected into a 150 ohm impedance. The measuring clamp enables this measurement. Note that eh RFIC-4-6 synthesizer features the monitoring and the associated control function.
