10Base-T Harmonic Content
18 10Base-T Harmonic Content
ANSI Section 1411.10.03
18.1 Test Purpose
To verify the harmonic content at the transmitter output.
18.2 Specification
When the UUT is driven by an all ones Manchester signal, each harmonic measured at the output of
the transmitter shall be at least 27 dB below the fundamental frequency.
18.3 Test Equipment
• Spectrum Analyzer
• CAT 5 twisted pair cable (under 2 inches in length)
• BNC cable, with 50-ohm characteristic impedance
18.4 Test Fixtures
Balun Test Fixture with 200 MHz or greater bandwidth (Appendix D.5)
18.5 Test Procedure
1. Insert CAT 5 cable into transmitter side of Balun fixture and connect Balun to Spectrum
Analyzer (or Network Analyzer) through a BNC cable as shown in Figure 18-1.
