Automatically Selecting Test Equipment in a Serial Connection Tab
When using the auto-detection feature to select test equipment, the
CDMA LMF examines which test equipment items are actually
communicating with CDMA LMF. Follow the procedure in Table 3-31
to use the auto-detect feature.
Table 3-31: Selecting Test Equipment Using Auto-Detect
Step Action
1 From the Tools menu, select Options.
The LMF Options window appears.
2 Click on the Serial Connection tab (if not in the forefront).
3 Select the correct serial port in the COMM Port pick list (normally COM1).
4 Click on Auto-Detection (if not enabled).
5 Type in the GPIB addresses in the box labeled GPIB address to search (if not already displayed).
NOTE
Refer to the Setting GPIB addresses section of Appendix F for instructions on verifying or changing
test equipment GPIB addresses, if necessary.
When both a power meter and analyzer are selected, the first item listed in the GPIB addresses to
search box will be used for RF power measurements (i.e., TX calibration). The address for a signal
generator is normally 1, a power meter is normally 13 and the address for a CDMA analyzer is
normally 18. If 1, 13,18 are included in the GPIB addresses to search box, the power meter (13) will
be used for RF power measurements. If the test equipment items are manually selected the CDMA
analyzer is used only if a power meter is not selected.
6 Click Apply. The button will darken until the selection has been committed. A check mark will
appear in the Manual Configuration section for detected test equipment items.
7 Click Dismiss to close the LMF Options window.
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.
Calibrate Test Equipment from the Util menu list is used to calibrate
test equipment item before being used for testing. The test equipment
must be selected before beginning calibration. Follow the procedure in
Table 3-32 to calibrate the test equipment.
Table 3-32: Test Equipment Calibration
