A setup screen with a series of tabs appears. See Figure 2
.
3 To navigate to a different setup screen, select the corresponding tab at the top of
the screen. For example, to display the Pattern setup screen, select the Pattern
tab.
4 After you finish specifying the test settings, select the Results soft key to return to
the Main screen.
For detailed instructions, refer to the Getting Started manual that shipped with your
instrument, and to
Chapter 2 “Data Communications Testing” and Chapter 3 “Diphase
Testing” in this manual.
Step 2: Performing a self test
After you configure your test, you should verify that the instrument is operating properly
by performing a self test for the interface before connecting to the circuit you are testing.
To perform a self test
1 Configure the test (see “Step 1: Configuring the test” on page 6 ).
The instrument uses the internal synthesizer as the clock source during a self
test; therefore, you do not need to specify a clock source for receive and transmit
timing, and certain settings will automatically be disabled.
2 On the Main screen, select the Loop action tab, then select Self Loop .
3 Verify that ALL RESULTS OK appears in the Summary category.
– If ALL RESULTS OK appears, the self test is successful, and the instrument and the
PIM interface are operating properly.
– If ALL RESULTS OK does not appear, and errors are listed in the Summary category,
there is a problem with the instrument or the PIM interface.
