Detecting Test Equipment
When Using Agilent E7495A
Be sure that no other equipment is connected to the LMF. The Agilent
E7495A must be connected to the LAN to detect it. Then perform the
procedures described in Appendix F, Table F-1, Table F-2, and
Table F-3.
Calibrating Test Equipment
The calibrate test equipment function zeros the power measurement level
of the test equipment item that is to be used for TX calibration and audit.
If both a power meter and an analyzer are connected, only the power
meter is zeroed.
The Agilent E4406A transmitter tester does not support
power measurement level zeroing. Refer to the Equipment
Calibration section of Appendix F for E4406A calibration.
