T est Set Calibr ation Chapter 3: LMF Oper ation
Calibration Procedures Included
Automatic
Procedures included in this section use the LMF automated calibration routines to determine
path losses of the supported communications analyzer , power meter , associated test cables,
adapters, and (if used) antenna switch that make up the overall calibrated test equipment set .
A fter calibration, the gain/loss offset values are stored in a test measurement offset file on
the LMF computer .
Manual
Agilent E4406A T ransmitter T ester - 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 T est Equipment function, the
LMF will return a status window failure message stating that zeroing power is not supported
by the E4406A. Refer to Appendix D T est Equipment Preparation for instructions on using
the instrument’s self -alignment (calibration) function prior to performing Bay Level Offset
calibration.
P ower Meters - Manual power meter calibration procedures to be performed prior to
automated calibration are included in Appendix D T est Equipment Preparation .
Cable Calibration - Manual cable calibration procedures using the Advantest R3465
communications system analyzer are provided in Appendix D T est Equipment Preparation ,
if needed.
Prerequisites
Ensure the following prerequisites have been met before proceeding:
• T est equipment is correctly connected and turned on.
• T est equipment addressing is set as required for the connection type being used (GPIB,
Serial, Network)
Calibrate Test Equipment Function (Except Agilent E4406A and
Anritsu MT8212B)
The Calibrate T est Equipment function zeros the power measurement level of the test
equipment item to be used for TX calibration and audit. If both a power meter and an analyzer
are connected, only the power meter is zeroed.
