Test Mode 5. Transmitter Power Spectral Density (PSD) and
Transmitter Peak Differential Output Tests
Test Setup
The Power Spectral Density (PSD) Test can be run using either a spectrum
analyzer or an oscilloscope. When using the Oscilloscope, refer to “General Test
Setup” on page 14 for testing using oscilloscope.
If you use the N9010B Signal Analyzer, convert the differential output to a
single-ended output using a balun. Use the balun on the N5395C Ethernet Test
Fixture as shown in Figure 1-19 on page 39.
