F-2 1X SC4812T–MC BTS Optimization/ATP 5/21/04
DRAFT
The Agilent E7495A signal generator is only calibrated down to –80db.
In order to achieve accurate FER testing, be sure the RX setup includes
at least 40db of attenuation. This will ensure the signal generator will
output sufficient power to operate in the calibrated range.
Set the IP Address as described in Table F-1.
Table F-1: Set IP Address on Agilent E7495A test set
n Step Action
1 Use 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.
Connections
Motorola recommends using 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 BNC
connectors.
The LMF will connect to the hub which in turn is connected to the BTS
and 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 to
the Hub:
– Ethernet cable, RJ–45–to–RJ–45. Be sure the LAN card is set for
either AUTO or to use the RJ–45 only.
– Coax cable between LAN card and Hub. Use a BNC “T” connector
on the hub. If the hub does not have BNC connectors, use a
BNC–to–UTP adapter with the “T” connector. Connect a coaxial
cable between the LAN card and one end of the BNC “T” crossbar.
Hub to BTS – With a BNC “T” connector on the hub, connect a coaxial
cable between the open end of the “T” crossbar and the BTS LAN
connection.
Detecting Test Equipment
Be sure no other equipment is connected to the LMF. The E7495A must
be connected to the LAN, as described above, for the LMF to detect it.
Perform the procedures described in Table F-2.
