NVP Calibration
The Determine Cable NVP function allows you to determine the NVP (nominal
velocity of propagation) for a known length of cable and save the value for
additional measurements of unknown lengths of the same type of cable. The
calibrated NVP value applies only to the selected test standard. You can also enter
a known NVP value or use the Set to Default softkey to set the NVP to
the default value, which is the NVP for a typical sample of the selected cable type.
To determine a cable’s NVP value, proceed as follows:
Notes
To determine a cable’s NVP, you should use a cable at least 15m
(50 ft) long. The recommended length is 30m (100 ft).
NVP is determined for the cable pair with the shortest electrical
delay.
1. Turn the rotary switch to SPECIAL FUNCTIONS.
2. Use D to highlight Determine Cable NVP.
3. Press E.
4. As prompted by the display, connect a known length of the appropriate cable
to the test tool. On Model DSP-2000, connect the cable to the CABLE TEST
jack.
5. Verify that no cables are connected to the unused cable connector or DB9
connector on the test tool.
6. Press T.
7. Use D or U to change the displayed length to the known length of the
attached cable. As you adjust the length measurement, the NVP value changes
automatically. The range for NVP values is 50.0% to 99.9%.
8. When the displayed length matches the known length of the cable, press S
to store the new NVP value and return to the main Special Functions menu.
To exit the screen without saving the new NVP value, press e.
If the message CABLE FAULT DETECTED appears, verify that the selected
cable type is correct, check the cable for proper pin connections, or calibrate with
a different cable.
