Automatically Selecting Test Equipment in the Serial Connection Tab

When using the auto-detection feature to select test equipment, the LMF

determines which test equipment items are actually communicating with

LMF. Follow the procedure in Table 3-29 to use the auto-detection

feature.

Table 3-29: Selecting Test Equipment Using Auto-Detect

Step Action

1 In the LMF window menu bar, click Tools and select Options... from the pull-down menu.

- The LMF Options window appears.

in the GPIB addresses for the test equipment to be used, separating each address with commas and no

spaces. (Refer to the Setting GPIB Addresses section of Appendix NO TAG for instructions on

verifying and/or changing test equipment GPIB addresses.)

NOTE

During the GPIB address search for a test equipment item to perform RF power measurements (that is,

for TX calibration), the LMF will select the first item it finds with the capability to perform the

measurement. If, for example, the address sequence 13,18,1 is included in the GPIB addresses to

search box, the power meter (GPIB address 13) will be used for RF power measurements. If the

address sequence 18,13,1 is included, the LMF will use the communications system analyzer (GPIB

address 18) for power measurements.

6 Click Apply.
