Five different antennas areavailable for use with the unit depending on the application. There are four horn antennas andone Wave-Stick antenna. The Wave-Stack antenna has several different part numbers whichcorrespond to the different lengths of waveguide that lead to the radiating potion of the Wave-Stick. We tested the 6in Wave-Stick.Unit TestedModel Number: BM702Serial Number: 0/311883.001Antennas:3in horn 21163401004in horn 21130101006in horn 21130001008in horn 2112540100Wave-Stick 3159860600Related Submittal(s) GrantsThere are no other approvals required for this device.

The actual test distance used is noted in the test datasheets. The device’s performance was investigated to 40GHz. The EUT was powered by a DCpower supply for all tests. All other performance tests were made in accordance with theprocedures outlined in Part 90 of CFR 47.Each of the antennas was investigated at the fundamental frequency to determine which was themost efficient radiator – this was the 8in horn antenna. Using the 8in horn antenna, harmonicsand spurious emissions were checked from 7 – 40GHz.Test FacilityCurtis-Straus LLCAll testing for the range 30–40000MHz was performed at Curtis-Straus (A2LA Certificate Number:1627-01). The open area test site used to collect the radiated data is located at 527 Great Road,Littleton, MA 01460. Site “M” was used..

Therefore field strength measurements with a horn antenna were doneinstead. The following is the calculation of the limit in field strength based on the limit in power.ERP = Equivalent Radiated PowerPD = Power DensityV = VoltsFundamental Maximum Measured Output =117.7dBµV/m = 0.767V/m @ 1mPD = (V/m)^2/(resistance of free space [Ω])PD = 0.7672/377PD = 0.00156W/m2ERP = 4πPD*R2ERP = 4π(0.00156)*12ERP = 19.6mW = 0.0196W = PfundEmissions 250% or more outside the fundamental should be attenuated by at least:43dB + 10 log Pfund25.9dBTo calculate the limit of the harmonics:E = 5.5/(distance) x SQRT(Ptot) - Formula for E-field from isotropic antennaPtot = 19.6mW – 25.9dB = 12.92dBm – 25.9dB = -13dBm = -43dBWPtot = 0.00005WE1m = (5.5/1) * SQRT (0.00005)E1m = 0.039V/m = -28.1dBV/m = 91.8dBµV/mE1m = 91.8 dBµµV/mTherefore the limit in field strength at 250% outside of the authorized bandwidth is as follows:E1m = 91.8 dBµµV/m
