Cable Calibration – Manual cable calibration procedures using the HP

8921A and Advantest R3465 communications system analyzers are

provided in the Manual Cable Calibration section of Appendix F, if

needed.

GPIB Addresses

GPIB addresses can range from 1 through 30. The LMF will accept any

address in that range, but the numbers entered in the LMF Options

window GPIB address box must match the addresses of the test

equipment. Motorola recommends using 1 for a CDMA signal generator,

13 for a power meter, and 18 for a communications system analyzer. To

verify and, if necessary, change the GPIB addresses of the test

equipment, refer to the Setting GPIB Addresses section of Appendix F.

IP Addresses

For the Agilent E7495A Communications Test Set, set the IP address

and complete initial setup as described in Appendix F (Specifically, see

Table F-1 on page F-3).

Selecting Test Equipment

Serial Connection and Network Connection tabs are provided in the

LMF Options window to specify the test equipment connection method.

The Serial Connection tab is used when the test equipment items are

connected directly to the LMF computer through a GPIB box (normal

setup). The Network Connection tab is used when the test equipment is

to be connected remotely via a network connection or the Agilent

E7495A Communications Test Set is used. Refer to Appendix F

(Specifically, see Table F-1 on page F-3).

Prerequisites

Ensure the following prerequisites have been met before proceeding:

S Test equipment is correctly connected and turned on.

S GPIB addresses set in the test equipment have been verified as correct

using the applicable procedures in Appendix F. (GPIB not applicable

with Agilent E7495A)

S LMF computer serial port and test equipment are connected to the

GPIB box. (GPIB not applicable with Agilent E7495A)

Selecting Test Equipment

Test equipment may be selected either manually with operator input or

automatically using the LMF autodetect feature.
