Automatically Selecting Test Equipment in Serial Connection Tab

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

examines which test equipment items are actually communicating with

the LMF. Follow the procedure in Table 3-26 to use the auto-detection

feature.

Table 3-26: Selecting Test Equipment Using Auto-Detect

n Step Action

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

LMF Options window appears.

2 If it is not in the forefront, click on the Serial Connection tab.

3 Select the correct serial port in the COMM Port pick list (normally COM1).

4 If it is not selected (no black dot showing), click on the Auto–Detection button.

5 If they are not already displayed in the box labeled GPIB address to search, click in the box and

type 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 F 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. The button will darken until the selection has been committed. A check mark will

appear in the applicable Manual Configuration section check boxes for detected test equipment

items.

7 Click Dismiss to close the LMF Options window.

Detecting Test Equipment when using Agilent E7495A

Check that no other equipment is connected to the LMF. Agilent

E7495A equipment must be connected to the LAN to detect it. Then

perform the procedures described in Appendix F (Specifically, see

Table F-1 on page F-3, Table F-2, and Table F-3 on page F-4).
