Manual
Agilent E4406A Transmitter Tester – The E4406A does not support
the power level zeroing calibration performed by the LMF. If this
instrument is to be used for Bay Level Offset calibration and calibration
is attempted with the LMF Calibrate Test Equipment function, the
LMF 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 F 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 F.
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
The E7495A communications test set uses IP over Ethernet connections
for communication rather than the GPIB. For the Agilent E7495A, set
the IP address and complete initial setup as described in Appendix F,
Table F-1.
Selecting Test Equipment
Other Than Agilent E7495A
Open the LMF Options window from the Tools > Options menu list to
select test equipment automatically (using the autodetect feature) or
manually.
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 through a network connection.
