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.
Selecting Test Equipment
Use LMF Options from the Options menu list to select test equipment
automatically (using the autodetect feature) or manually.
Prerequisites
A Serial Connection and a Network Connection tab are provided for
test equipment selection. The Serial Connection tab is used when the
test equipment items are connected directly to the CDMA LMF
computer via a GPIB box (normal setup). The Network Connection tab
is used when the test equipment is to be connected remotely via a
network connection.
Ensure the following has been completed before selecting test
equipment:
 Test equipment is correctly connected and turned on.
 CDMA LMF computer serial port and test equipment are connected to
the GPIB box.
Manually Selecting Test
Equipment in a Serial
Connection Tab
Test equipment can be manually specified before, or after, the test
equipment is connected. CDMA LMF does not check to see if the test
equipment is actually detected for manual specification.
