Modifications None Test Exercise (e.g software description, test signal, etc.) The DUT was placed in continuous transmit mode of operation. Applicable Standards ANSI/TIA 603-C: 2004, FCC CFR 47 Parts 2 and 74, RSS- 123 Issue 1, Rev. 2 Applicant: AZDEN CORPORATION FCC ID: BZB2000XT IC #: 2817B-2000XT MODEL #: 2000XT REPORT: A\AZDEN_BZB\1098AUT12\1098AUT12TestReport.doc Page 6 of 17 TEST PROCEDURES Power Line Conducted Interference: The procedure used was ANSI/TIA 603-C: 2004 using a 50uH LISN. Both lines were observed with the DUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: For a device with a fixed antenna, RF power is measured as ERP as the antenna is permanently attached. The substitution method was used as described in ANSI/TIA-603-C: 2004. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th Harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz , the VBW = 3 MHz, and the span 50 MHz. Radiation Interference: The test procedure used was ANSI/TIA 603-C: 2004 using an Agilent spectrum receiver with preselector. The bandwidth (RBW) of the spectrum receiver was 100 kHz up to 1 GHz and 1 MHz above 1 GHz with an appro…
