Configuring a Custom Cable
The Configure Custom Cable function allows you to define custom test standards
for up to four custom cables. You can change the following parameters for your
custom configuration:
• Baseline standard for cable definition
• NVP (Nominal Velocity of Propagation)
• Maximum cable length
• Fault threshold for impedance anomalies
• Active pair assignments for cable pairs
• Resistance
• Characteristic impedance test enabled or disabled
• Attenuation test enabled or disabled
• NEXT and NEXT@REMOTE tests enabled or disabled
• RL test enabled or disabled
• ACR and ACR@REMOTE tests enabled or disabled
• PSNEXT and PSNEXT@REMOTE tests enabled or disabled (Model
DSP-2000)
Note
To determine the NVP for a custom cable configuration refer to the
previous section, “NVP Calibration.”
During the configuration process, you can abandon the changes you have made by
pressing ! Abort. To reset a parameter back to the default value, highlight
the parameter; then press @ Set to Default. To reset all of the
parameters back to default values, highlight the test standard on Page 1 of 6 of the
configuration screens; then press @ Set to Default.
