CHAPTER 5: Quick Check
5. Quick Check
Quick Check is an abbreviated Autotest, designed to be completed in less
than 10 seconds. It’s used for quick installation checks.
Quick Check performs these tests on twisted-pair cables: Wire Map, Near-
End Crosstalk (NEXT) at both ends for Two-Way testing, Attenuation,
ACR, and Length. These additional tests may be added to the Quick Check
suite of tests by defining a Custom Cable standard: Impedance,
Propagation Delay/Delay Skew, Power Sum NEXT, Cable Grading, and
Resistance.
NEXT and Attenuation tests take measurements at a reduced number of
test points covering the entire frequency range. For this reason, Quick
Check is not a cable certification test;
the results cannot be saved
.
5.1 Running Quick Check
1. Connect one end of the cable to the main unit and the other end to
the remote unit.
2. Set the remote unit’s dial to REMOTE.
3. Set the main unit’s dial to Quick
√
. The test begins automatically.
(Press the arrow keys to change the cable test standard.)
4. Press Start (F1) to re-start Quick Check. Press VIEW (F3) to review
Quick Check test results.
5.2 Viewing Quick Check Results
Viewing the results of Quick Check is the same as for Autotest, except that
they cannot be saved. Refer to

ESULTS
A PASS* or FAIL* result (PASS or FAIL with an asterisk) indicates that a
measured NEXT or attenuation value is close enough to the Test Standard
that it is within the SCAN-LAN VI’s measurement uncertainty. As a result,
the PASS or FAIL judgment is uncertain, and therefore the SCAN-LAN VI
cannot determine with confidence whether the link conforms to the Test
Standard.
