PRELIMINARY

Manual

Agilent E4406A Transmitter Tester – The E4406A does not support

the power level zeroing calibration performed by the WinLMF. If this

instrument is to be used for Bay Level Offset calibration and calibration

is attempted with the WinLMF Calibrate Test Equipment function, the

WinLMF will return a status window failure message stating that zeroing

power is not supported by the E4406A. Refer to the Equipment

Calibration section of Appendix B for instructions on using the

instrument’s self–alignment (calibration) function prior to performing

Bay Level Offset calibration.

Power Meters – Manual power meter calibration procedures to be

performed prior to automated calibration are included in the Equipment

Calibration section of Appendix B .

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 B, if

needed.

GPIB Addresses

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

any address in that range, but the numbers entered in the WinLMF

Options window GPIB address boxes (Table 6-23 and Table 6-24) must

match the addresses set in 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 B.

Selecting Test Equipment

Serial Connection and Network Connection tabs are provided in the

WinLMF 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 WinLMF 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.

Prerequisites

Be sure the following have been completed before selecting test

equipment:

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 B.

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

GPIB box.
