The Even Sec SYNCconnection is required.The Agilent E7495A signal generator is only calibrated down to –80db.In order to achieve accurate FER testing, be sure the RX setup includesat least 40db of attenuation. This will ensure the signal generator willoutput sufficient power to operate in the calibrated range.Set the IP Address as described in Table B-1.Table B-1: Set IP Address on Agilent E7495A test setnStep Action1Use the System Button > Controls >IPAdmin to set an IP address on the E7495A as 128.0.0.49,and Netmask to 255.255.255.128. ConnectionsIt is recommended that you use a hub with BNC and RJ–45 connections.[Suggested models: Netgear model EN104 (4 port) or EN108 (8 port).Do NOT use model numbers ending with “TP”; those have no BNCconnectors.]The LMF will connect to the hub which in turn is connected to the BTSand to the Agilent E7495A.Agilent E7495A to Hub – This is an Ethernet cable, RJ–45 to RJ–45.LMF to Hub – Use one of the following cables to connect the LMF tothe Hub:– Ethernet cable, RJ–45 to RJ–45 (be sure that the LAN card is set foreither AUTO or to use the RJ–45 only).– Coax cable between LAN card and Hub. (Use a “T” on the hub andconnect a cable between the other end of the “T” and the BTS LANconnection).Hub to BTS – Use BNC “T” connector on the hub. [If your hub doesn’thave BNC ports, use a BNC to UTP adapter.]B](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5EJ1.User-Manual-Part-4/User-Guide-430570-Page-28.png)

Thus, only components having losses ≤30 dBshould be measured using this method. For further accuracy, always re-zero the power meterbefore connecting the power sensor to the component being calibrated. After connecting thepower sensor to the component, record the calibrated loss immediately.18 Disconnect all components in the test setup and calibrate each one separately by connecting eachcomponent, one-at-a-time, between the RF OUT ONLY PORT and the power sensor. Record thecalibrated loss value displayed on the power meter.SExample: (A) Test Cable(s) = –1.4 dB(B) 20 dB Attenuator = –20.1 dB(B) Directional Coupler = –29.8 dB19 After all components are calibrated, reassemble all components together and calculate the total testsetup loss by adding up all the individual losses:SExample: Total test setup loss = –1.4 –29.8 –20.1 = –51.3 dB.This calculated value will be used in the next series of tests.20 Under Screen Controls press the TESTS button to display the TESTS (Main Menu) screen.. . . continued on next pageB](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5EJ1.User-Manual-Part-4/User-Guide-430570-Page-59.png)
