CQ Auto Test
The cable qualification auto test function allows you to automatically run
tests used in pre-qualification, installation, and maintenance of different
circuit types from POTS to VDSL2. Auto tests include a range of different
tests that compare measured results against stored threshold values to
provide pass or fail results. The results are displayed in both text and
graphical format.
The following tests can be included in the CQ auto test function:
³
AC/DC voltage and current
³
Resistance
³
Capacitance
³
Isolation
³
Load coil detection
³
Power influence
³
Voice frequency (VF) longitudinal
balance
³
Voice frequency (VF) noise
³
Voice frequency (VF) impulse noise
³
Voice Frequency (VF) receive tone
³
Wideband (WB) receive tone
³
Wideband (WB) longitudinal balance
³
Power spectral density (PSD) noise
³
Attenuation
³
Wideband (WB) impulse noise
³
Time domain reflectometry (TDR)
