General Test Setup
Test Modes 1, 2, 5, and 6 require only the Infiniium oscilloscope and the device to
be tested (Device Under Test or DUT). The test setup is described below.
Differential Signal supplied to the Oscilloscope can be achieved either by using
Two Oscilloscope Channels or a Single Differential Probe . The type of
connection accepted can be selected in the Setup tab of the test application.
Two Oscilloscope Channels refers to connecting the differential automotive pair
to the oscilloscope using only SMA cables. Refer to Figure 1-1 for more details.
Single Differential Probe refers to connecting the differential automotive pair to
the Oscilloscope using a single differential probe. Refer to Figure 1-2 for more
details. The only variation would be the Power Level Test that requires a balun.
Any variation from the above definition of differential signaling type is not
recommended.
Test Mode 4 requires the N5395C Ethernet Test Fixture and an Arbitrary
Waveform Generator (AWG). Refer to “Test Mode 4. Transmitter Distortion and
MDI Return Loss” on page 29 for specific setup details.
Test Mode 4 also includes an MDI S-Parameter Test.
Test Mode 5 can also use the N9010B Signal Analyzer. Refer to
“Test Mode 5.
Transmitter Power Spectral Density, Transmitter Power Level and Transmitter
Peak Differential Output Tests” on page 36 for specific setup details.
NOTE
For all tests, use the software supplied with your transmitter PHY to control the
Device Under Test.
