Scope This statement of work defines the requirements of a far-field antenna measurement range, which includes (1) One 560 cm (W) x 325 cm (H) x 620 cm (L) Antenna Measurement Anechoic Chamber, detailed requirements refer section B . (2) One Far-field Antenna Measurement System with spinning linear CP measurement capabilities, detailed requirement refer section E & F . (3) One broad-band transmitted antenna, detailed requirements refer section G . B. Antenna Measurement Anechoic Chamber Fully anechoic chamber with dimension 560 cm in width, 325 cm in height and 620 cm in length. The quiet zone of this Chamber shall be greater than Page 9 of 16 WIESON TECHNOLOGIES CO., LTD. 60 cm @ 400MHz~900MHz, 43 cm @2.4 GHz, 31 cm @5.8 GHz,. Contractor should be aware of this anechoic chamber is going to be used for performing far-filed antenna measurement. C. Electrical specifications Frequency Range: 400 MHz to 6 GHz, Quiet zone size: >60 cm @ 400MHz~900MHz, >43 cm @2.4 GHz, >31 cm @5.8 GHz. Quiet zone ripple: < +/- 1.5 dB @500(400)MHz~800MHz, < +/-0.75 dB @800MHz~1.5GHz, < +/- 0.5 dB @1.5GHz~6.0GHz Field Probing Frequency Peak-to-Peak Amplitude Taper (Within specified Quiet Zone Area) Quiet Zone Size (cm) Compliant 0.9 GHz < 0.75 dB 60 Yes 1.575 GHz < 0.5 dB 43 Yes 1.8 GHz < 0.5 dB 43 Yes 2.4 GHz < 0.5 dB 43 Yes 5.8 GHz < 0.5 dB 31 Yes Page 10 of 16 WIESON TECHNOLOGIES CO., LTD. D. Absorbers We shall design and install proper absorbers on the inner walls of the chamber to guarantee the electrical specifications. However, the absorbers height shall be no less than 24" which enables the space in the chamber to be around 438 cm (W) x 203 cm (H) x 513 cm (L). All the absorber used shall meet NRL-8093 fire retardant regulations E. Far-field Antenna Measurement System We shall supply all the hardware and software which are capable of characterizing antenna radiation patterns from 30 KHz to 6 GHz using the existed Agilent 5230A PNA-L or Agilent 8753ES Vector Network Analyzer. The system shall be able to automatically measure and plot single axis amplitude and phase antenna patterns in either Cartesian or polar formats. F. Far-field measurement software The software consists of the control or data acquisition software and the data plotting software. (1) The data acquisition software shall at least be capable of the following functions: *measuring single frequency per cut - single axis (azimuth); system can a…
