The EUT was manufactured and tested by BEI Electronics LLC located in Quincy, IL. 2.2 Purpose The test series, using the required measurements of 47 CFR 2.1055, was performed to certify that the EUT meets the FCC 47 CFR 73.1545 Carrier frequency departure tolerances requirement. 2.3 Deviations, Additions and Exclusions There were no deviations, additions to, or exclusions from the test specification during this test series. 2.4 Laboratory Conditions The ambient temperature at the time of the test was 22 °C and the relative humidity was 48% 3 APPLICABLE DOCUMENTS The following documents of the exact issue designated form part of this document to the extent specified herein:  FCC 47 CFR 73.1545 “Carrier frequency departure tolerances.”, dated 10-1- 12  FCC 47 CFR 2.1055 “Measurements required: Frequency Stability.”, dated 10- 1-09 4 EUT SETUP AND OPERATION 4.1 General Description The EUT is a 500W FM Broadcast Transmitter, Part No. STXe 500. A block diagram of the EUT setup is shown as Figure 1. 4.1.1 Power Input The EUT obtained 115V 60Hz single-phase power via a 3 wire, 1.8 meter long, unshielded power cord. 4.1.2 Peripheral Equipment A BEI Electronics LLC XPi 10esp GPS locked 10MHz output was used as the timing reference for the Hewlett Packard HP5316B Universal Frequency Counter to acquire accurate frequency readings. Page 5 of 9 4.1.3 Interconnect Cables The EUTs signal input and output ports were filled as follows: EUT Port Cable 1 PPS IN Not Connected 10MHz IN Not Connected Ethernet Connected to a Netgear FS576 Ethernet Switch, via a 7.62 meter long CAT 5 cable COM IN Not Connected COM OUT Not Connected EXC RF OUT Connected to a HP 5316B Universal Counter, via a 1 meter long coaxial cable PA RF IN Not Connected AES1 Not Connected LEFT Not Connected RIGHT Not Connected SCA2 Not Connected 19kHz OUT Not Connected SCA1 Not Connected RDS Not Connected RF OUT Not Connected 4.1.4 Grounding The EUT was grounded only through the ground wire of its input power cord Page 6 of 9 4.2 Operational Mode For all tests the EUT and all peripheral equipment were energized. The EUT audio source was set to Composite with no external audio connection. The EUT was set to transmit a 100.0 MHz unmodulated carrier signal. The EXC RF Out port was connected to a HP 5316B Universal Counter for frequency measurement. 4.3 EUT Modifications No modifications were required for compliance with the FCC requirements. 5 TEST INSTRUMENTATION 5.1 Test Instrumentation The test instrumentation and auxiliary equipment used du…
