Laplace Instruments Antennas

RF200 Broadband EMC Log Periodic Antenna
A conventional log periodic antenna complete with stand and adapter to enable vertical and horizontal polarization modes, and height adjustment from 1m to 2m

The RF200 is designed to cover the whole range from 30MHz to 1GH in one sweep. No need to change antenna part way through the scan.

CALIBRATION
The RF2xx design is fully calibrated on the 10m OATS site at NPL. This data is included with each antenna. For emissions measurement, the RF200 is used in conjunction with the SA1020 pre-amplifier. This 'head' amplifier improves sensitivity and decouples the output lead from the antenna, avoiding
spurious cable influences on the results.
> One antenna covers complete band C and D
(30MHz - GHz)
> Compact antenna for 700MHz - 4GHz
> Supplied with calibration data
> Excellent sensitivity, ideal for EMC testing
> Vertical and horizontal polarization

COMPREHENSIVE
The RF200 is designed to cover the whole range from 30MHz to 1GH
in one sweep. No need to change antenna part way through the scan.

The RFxx range are specifically designed for general use as EMC emissions measurement antennas. They combine excellent broadband characteristics with high sensitivity and sturdy
construction.
Although primarily used with the Laplace range of analyzers and receivers, they can be used with any other receiver and are supplied with full calibration data so that antenna factors can be entered into
any third party system.

In order to achieve optimum performance stability, the RF200 is designed to work with the SA1020 pre-amplifier, located at the head of the support.
This improves sensitivity and ensures that cable configuration does not affect results.
The RF200 is supplied complete with rigid stand and the RF230 is complete with an all plastic miniature tripod.

RF300 Van Veen Large Loop Antenna
a fully compliant, 3 axis 2m diameter loop antenna, complete with non-metallic stand, current transducers, loop switching system and cables. To enable on-site calibration, a calibration loop is available, manufactured strictly in accordance with CISPR16.
 
  • Kay Features:
  • · This antenna is specified in EN55015 for the measurement of luminaries
  • · CISPR15 and CISPR16 compliant
  • · Includes all 3 axes with PVC frame and all connecting cables
  • · Optional calibration loop as specified in CISPR15/16
  • · Shipped in compact form, ready for assembly on-site
  • · Includes full instructions and all parts required for assembly
  • · Each antenna is individually calibrated and issued with manufacturer's calibration certificate.

RF300C Calibration Loop
A calibration large loop (RF300C) is available as an option if on-site calibration is deemed necessary. The RF300C allows the calibration loop to be used on all three axes and rotated within each as required by the standards.

The RF300C large loop calibration loop is manufactured to comply with CISPR16. Full details of the use of this loop are provided in this standard. This item (RF300C) is available as a separate option to go with the RF300 Large Loop Antenna. The RF300 is supplied fully calibrated but the calibration loop is available to those who wish to check the calibration at regular intervals, and to ensure that the calibration is not affected by the environment.
