QPHY-10GBase-KR Testing
Test Preparation
Before beginning any test or data acquisition, the oscilloscope should be warmed for at least 20
minutes.
Calibration is automatic under software control and no manual calibration is required. This
procedure will be run again if the temperature of the oscilloscope changes by more than a few
degrees.
QPHY-10GBase-KR Test Configurations
Test configurations include variable settings, limit sets, and test selections. See QPHY-
10GBase-KR Variables for a description of each variable and its default value. See the QPHY-
10GBase-KR Limit Sets for more information about the default test limits.
DEMO Mode
This configuration performs a demonstration of all tests covered in QualiPHY 10GBase-KR
using stored waveforms. The limit set in use is IEEE 802.3ap limits. All variables are set to their
default settings except that Test Mode is set to Use Saved Data, Saved Waveform Path is set to
D:\Waveforms\10GBaseKR\Demo, Demo Mode is set to Yes. The tests performed are:
• Jitter (Tj, Rj, Dj, DCD and Bit Rate)
• Voltage Measurements (Single ended)
• Transition Time Measurements
• Tx Equalization
Run Live with Pauses, Single Ended Inputs on row A
The configuration generates the specification-required measurements and eye diagram as
described in section 72.7 of IEEE 802.3ap-2007. All variables are set to their default settings.
The tests performed are:
• Jitter (Tj, Rj, Dj, DCD and Bit Rate)
• Voltage Measurements (single ended)
• Transition Time Measurements
• Tx Equalization
