The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
Only Test at Highest Bit Rate
Specify whether to run the Intra-Pair Skew test on only the highest bit rate. The Compliance Test Specification
Rev. 1.1 only requires this test to be run at the highest bit rate, however this option allows you to run this test at
both the High Bit Rate and the Reduced Bit Rate. This only applies when Bitrate(s) to Use For Test is set to
Both. Default is Yes.
3.10 AC Common Mode Noise
Output Level to Test
Specify which output level to use for the AC Common Mode test.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
Pre-emphasis Level to Test
Specify which pre-emphasis level to use for the AC common mode test.
The choices are: 0 – 0 dB, 1 – 3.5 dB, 2 – 6.0 dB or 3 – 9.5 dB or any combination. The default value is 0dB.
3.11 & 3.12 Non-ISI and Total Jitter Measurements
Output Level to Test
Specify which output level to use for the Non-ISI and Total Jitter tests.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
Pre-emphasis Level to Test
Specify which pre-emphasis level to use for the Non-ISI and Total Jitter tests.
The choices are: 0 – 0 dB, 1 – 3.5 dB, 2 – 6.0 dB or 3 – 9.5 dB or any combination. The default value is 0dB.
3.14-3.16 Spread Spectrum Tests
This consists of Main Link Frequency (3.14), SSC Modulation Frequency (3.15) and SSC Modulation Deviation
(3.16).
Output Level to Test
Specify which output level to use for the Spread Spectrum tests.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
