5 2 CLIENT INFORMATION Company Name Contact Person Laird Bill Steinike Address W66 N220 Commerce Ct. Cedarburg, WI Equipment Under Test (EUT) Information The following information has been supplied by the client Product Name Model Number MAC Address RM024 RM024-P10-M-30 00:50:67:C0:79:D8 2.2 Product Description The RM024 RAMP module is based on Laird's LT2510 core technology, enhanced with a new RF front end for improved sleep, improved link budget and a switchable antenna output. The device uses FHSS air interface protocol. The module has a maximum output power of 7.13 dbm. The antennas used in in testing include, Laird WIC2450-A chip antenna (gain +2 dbi), and Nearson S151-6 PX-2450S dipole antenna (gain +2 dbi). This gives the module an e.i.r.p of 9.13 dbm. Associated models: RM024-P10-C-xx RM024-P10-M-xx RM024-S10-C-xx RM024-S10-M-xx 2.3 Modifications Incorporated for Compliance None noted at time of test 2.4 Deviations and Exclusions from Test Specifications None noted at time of test Page 5 of 16

6 2.5 Performance Criteria (Immunity) Product Specific Criteria: EUT setup during immunity and susceptibility testing: The system was setup to have continuous communication between two RM024 modules through a PC running Laird Configuration/Test Utility. Minimum Performance level specified by manufacturer: The device may have loss of connection to the app while the test is performed. When the stress is removed, the device shall operate as intended, with no loss of function and connect to app. No user intervention on the EUT is permitted. 3 REFERENCES Publication Edition Date ETSI EN V ETSI EN Draft V ETSI EN Draft V Page 6 of 16

13 5.2 Radiated Immunity The EUT is illuminated with uniform electromagnetic radiation by means of a RF generator, power amplifier, and field generating antenna. Description of Measurement Ferrite panels and/or absorbers are placed on the ground between the antenna and EUT to achieve a uniform field area. The UFA is measured with an isotropic probe positioned in a planar grid at the desired test distance. The power required to create a uniform test field strength is stored in a calibration file for each frequency and antenna polarity. The response of the EUT during and after test is observed, recorded, and compared to the defined performance criteria.
